BOATSetc

The Marblehead (M) class is probably the most exciting to sail with its moderate size and light weight combined with high manoevrability and stability. Essentially a box rule with minimal constraints. A modern M will usually be made almost entirely of carbon fibre - hull, foils, spars and fittings.

The class was the first to adopt hi tech construction in the early 90s and development since then has been limited. This permits almost all boats built since then to be compete well in modern fleets.

The class is quite often referred to as the "Formula One" of radio sailing.

BOATSetc is your source for high performance pre-preg carbon RC sail boats. We can provide hulls, kits through to ready to sail boats.

If the famous design of Marc Pomarede succeeds the already successful Tramontane, this boat beats all records at the moment and is on the top of the list internationally and nationally. Based on paper plans, it was our task to develop the complete production process from digitization to mold production. The aim was to make the boat as cheap as possible, but without sacrificing quality. After making numerous prototypes, we are now able to produce boats in reasonable time.

  • moulded in pre-preg carbon
  • weight of about 320 grams with openings trimmed
  • natural black carbon finish
  • centre deck with deck level pot recess & foredeck built in
  • fin box and mast tube moulding built in
  • foredeck cut outs and hatch opening for access to rc are formed
  • witness marks for setting out positions of fittings
  • hulls are left with the surface as moulded
  • bow bulkhead is low density epoxy filler
  • stern is already closed

The Nioutram is available as a kit from about 1.490€  (incl Tax plus shipping)

Quark is the current design of our technology partner SAILSetc. Suitable for use with swing rigs or traditional rigs, QUARK is capable of performing well across the wind speed range. Characteristic of SAILSetc designed boats is their ability to perform for sailors of all skill ranges and in a wide range of conditions. Not only can they give excellent results for some of the best sailors (there were three QUARKs in the top 6 places at the 2014 world championship) but they can also give better results for sailors lower down the finishing results. This is partly due to their reliability imparted by the build quality and partly due to the handling qualities imparted by their fundamental and detail design.

  • recesses for the snap in/out rigging screw system

The Quark is available as a kit from about 1.950€  (incl Tax plus shipping)

IRSA Marblehead Class

The IRSA Marblehead (M) class is probably the most exciting to sail with its moderate size and light weight combined with high manoevrability and stability. Essentially a box rule with minimal constraints. A modern M will usually be made almost entirely of carbon fibre – hull, foils, spars and fittings. 

DSC 0571-001

The class was the first to adopt hi tech construction in the early 90s and  development since then has been limited. This permits almost all boats built since then to be compete well in modern fleets.

The class is quite often referred to as the “Formula One” of radio sailing.

The Marblehead class is managed by its own International Class Association, the IMCA. Please visit the class website at  www.marbleheadclass.org

The M or Marblehead Class, sometimes called the "50/800", is a remote-controlled high performance development class. It's original concept in the 1930's was to produce the largest model that would conveniently fit in the standard American car of the time. The class has been highly developed over the years to produce a high performance model that can be sailed in a wide range of conditions, assuming the owner has the appropriate rigs. Boats are available from several suppliers who can provide them from basic kit form to fully assembled.

The Marblehead class (M) is probably the most exciting to sail with its minimal rule structure and modern construction techniques a modern M will usually be made of carbon fibre and kevlar with full carbon rigs. The rules do allow for most boats from the mid 90’s onward to be modernised and still hold their own in current fleets.

NEWS 2024 Season Racing Schedule Coming Soon American Marblehead Class Website   1930 Model Yachting booklet          

rc marblehead yacht

Birthplace of the "Marblehead Class" and home to the new " American Marblehead Class" . If it's a Marblehead we sail them!

We also have a large fleet of CR 914 s sailing as well as Dragon boats ... and International, AMYA Ms .

Anyone interested in learning about, watching, or participating in the sailing of these yachts check out our 2019 schedule under the "Racing Information" tab to see our schedule.

In the schedule you'll see three designations for Marbleheads.

AM American Marblehead Class (encompasses all years)

M is for more modern designs @1990 designs and up.

VM is for Vintage Marbleheads , designs up to @1972. It has two divisions, Traditional and High Flye r.

AM stands for the new American Marblehead which encourages any Marblehead from any era to sail together and be scored according to it's division. Marbleheads from all eras, whether home built or professionally built all share two basic traits. They measure 50 inches long and are allowed 800 square inches of sail.

If you've got a boat 50 inches long bring it to the pond and let our group see what you have.

Come on down and join us!

Marblehead T50

The Marblehead T50 is one of the newer additions to the Tippecanoe family of beautiful model sailboats! Designed by Will Lesh, the Marblehead T50 is specifically made to race in the highly competitive Marblehead (50/800) class . The Marblehead T50’s concept is based on the more traditional T50 Racing Sloop and T50 Carbon Fiber Racing Sloop . Then, everything has been taken to the extreme for the optimum in speed and performance.

rc marblehead yacht

The Marblehead T50’s  super powerful, tall rig (in fact, the rig alone is over seven feet high!) is outfitted with sleek, fast mylar racing sails. A super light-weight carbon fiber and kevlar hull, sophisticated and strong high-performance sail servo, and the high tensile stainless steel single-strand rigging wire also help to increase power and to keep the Marblehead T50 extremely light.

rc marblehead yacht

The hull, including all the RC gear and batteries, weighs a mere 1 pound 11 ounces! To support the very tall ‘A’ rig, the keel bulb is seven pounds.

The Marblehead T50 is the ultimate in Marblehead Class racing! If you are looking for a boat which also sails beautifully and is made with less of an emphasis on weight reduction and class racing, you may want to also consider the T50 Racing Sloop. The T50 Racing Sloop’s build process is moderately complex, but not difficult, while the Marblehead T50’s building process is  complex with considerable detail.

If you have questions about which boat is right for you, feel free to email or call us:

 ::  Building Marblehead - Bill Bradley from New Zealand has commenced building a GOTHIC Marblehead from the board of Frank Russell. This design is a development of Franks IOM design GOTH of which Bill has already built a few. Frank generously provides the plans as a free download

Anyone wanting to contact Bill Bradley can email him at    [email protected]

We will follow the build as Bill progresses through the various stages. Bill had this to say about the build:

"I am just getting the frames set up on the base to build the plug. I am intending to build off the plug instead of making a mould as I am experimenting with the cloth layup. Initialy am using a 200g carbon weave with an 80g e glass over for sanding. Am looking at building 4 hulls as there are 4 interested parties including myself."

                            

 

- Bill is now making the deck - see photo's and his words below:

m almost ready to take off the first hull have just f/glassed the deck which will need sanding. carbon. nce the hull is taken off, it can be held in the same cradle and positions of mast, fin can be squared off down to c/line of hull. m intending to have the hull and deck in 3 pieces, ie hull, foredeck and flat rear deck. he bow, stern and bulkhead be made out of 3mm marine ply.  " - Bill has completed the plug and is making his final decision on the cloth to use - he says


- Bill has decided on the cloths he will use and has laid up the deck - he writes:

ave made a descision on the materials, although on the expensive side I think they will be the right ones. I have gone with a 125g E glass cloth first, followed by a layer of 155g k1 twill weave carbon, finished off with a fine weave 77g  Fglass for sanding. As can be seen in the photos I have added to the plug a small raised area towards the stern as the exit point for the steering arm from the servo. All going well I will remove the deck from the plug tomorrow and do the same for the hull over the weekend. Points to remember when cutting the carbon clothe always use masking tape on the clothe and then cut on he centre of the tape.

    - Hi guys, I've done it, my first carbon Boat, and not without a few mistakes, mainly in the cutting of the cloth. If you are setting up to cover a plug allow a good 100 mm longer than the length of the hull. It is amazing how much extra is required as the cloth follows the curve of the hull from bow to stern. I always like to trim the cloth on the plug when still green and before removing, as you can get a very true straight line for the gunwhale. However be carefull with the blade you are using and the angle of the line you are cutting on, you can over cut and lose some of your hull or deck. The next test for me is to remove the hull from the plug, I am not going to do this for a day or two until the carbon has hardened some more. Might be a week or two before my next email as i have not got the finbox yet - Bill has had a setback with glassing, but has been honest enough to explain it, which is something we can all learn from - He explains: not fit with my philosophy of keeping costs down and make it simple.          - Bill has sent 2 emails - see below glued in 2 x 10mm x 2mm cedar strips to form the gunwhale, I have a carbon rod from the foredeck down to the bottom of the hull to take the loadings on the forestay, the fin box has been trimmed and a carbon skirt at deck level has been fixed in place to to fix the deck down on to so as  not to let the water in. I have fixed the ainsheet post, drilled a hole for the rudder tube, and put extra timbers (cedar) at the stern for the deck block and the backstay eye. Have also got blocks either side to take the eyes for the rigging turnbuckles. I have installed two deck timbers to hold the hull at its correct width at deck level, one mid foredeck and one just aft of the mainsht post.As can be seen from the photos I am in the process of installing a mast ram on the raised foredeck, the mast ram in its tube will be on the top of the fin so as to connect with mast above the bearing race at the top of the gooseneck (am doing this as I go so will show details next time. Am thinking that I might run the sheet to the foredeck position for the jib thru a tube in the bulkhead thru to the foredeck . This will help to keep the sheet away from the winch. Also not shown in the photos I have glued a small plastic container on the side of the fin case angled up at 45 degrees to take the battery  The container is a 185ml pill container with its top cut off and is positioned just foreward of the circular hatch so as the battery simply drops in. At the bottom of the container I have drilled a hole so as moisture can exit. All up without the bulb and any fittings other than what I have glued to the hull it weighs 790grams. - Bill is getting close to completion, with a couple of alterations - he writes: ave had a major alteration, I have removed the mast ram fin as I am now installing on the mast stump a standard fix to the face of the mast ball bearing race gooseneck similar to ioms. This will enable me to have the ram in a tube under the foredeck. Bill


- Bill has just about got everything finished - Just the electrics to fit and using the rig off his Dibley Marblehead, he will soon be ready for the maiden voyage.

- Bill writes: "

- Bill writes his final thoughts on the build:

post, thr one circular 100mm dia hatch. After thoughts have been, a wire surround to prevent the mast ram from falling out and a push button switch activated thru the sticky back on the edge of the cut out in the deck. "

History of the Marblehead Class

rc marblehead yacht

Young skippers on the rocks besides Redd’s Pond, Marblehead, late 1890s.

rc marblehead yacht

A flotilla of 450s on Redd’s Pond in the late 1920s.

The Marblehead club was always a bit of a maverick in model yachting circles because it was large enough (70 members in 1930) to support classes of its own. Throughout the 1920s a very popular local class was the one originally suggested by the full-scale designer L. Francis Herreshoff : 450 in 2 of sail area and no other restrictions.

The plans shown here are for a design by C.W. Sweet. LWL 30.5 in, LOA 39 in, Displacement a mere 4.5 lb.

The 450 class, like other classes with no hull restrictions, lead to long, handsome “greyhound” shapes with extreme overhangs.

rc marblehead yacht

One of the first M Class boats, by Roy Clough.

In 1930 Roy Clough, then commodore of the club, proposed a new class of larger boats. The first published reference we have is from Model Yachting for Oct–Nov 1930:

The 450 class has been so popular, with so many boats racing in it at Marblehead, that a larger sail area class has been started there. These boats must be 50 inches on deck. At first it was proposed to carry 700 sq. in. of sail, but after trying one out with 795 the question as to whether the sail shall be increased to 900 or 1000 sq. in. is to be brought up at a meeting of the club.

The result, of course, was that the sail area was settled at 800 in 2 , and the single most popular class in the history of model yachting was launched. Called variously the “Marblehead,” “50/800,” or “M” class, it had at one time over 1000 registered boats. The class became a national class in the US in 1932 and an international class in 1937. There were many reasons for its popularity: the size of the boat made for a good sailing model in all kinds of weather and was still (by design, it was rumored) small enough to fit in the back seat of a car. The simplicity of the rules contrasted with the other classes of the day, which required extensive measurement to determine whether a boat was legal.

In 1936, Roy Clough wrote how the Class was inspired:

I would now like to tell you how this class came into existence. The idea of building a boat of this size came to me suddenly one Sunday morning when my club was racing the old 450 square inch sail area class. Looking out on the pond, I was all at once conscious that although the class was limited to 450 square inches of sail we had a real ‘mongrel’ class of boats. Boats of all sizes, from 30 to 45 inches long; regular keels, fin keels, overhanging rudders, and boats anywhere from five to ten inches wide all belonged in the same class! I went home that Sunday morning and drew my dream boat in profile and sail plan on an old barn door. Different members of the club came to see it and were very favorable, so after drawing it up on paper and then building the boat, the interest began to increase, and soon there were twelve boats being built from that plan, each with a few individual changes. From that time on, our membership began to increase, and we had to hire larger quarters. New clubs seemed to spring up overnight, and things started to boom for the Marblehead class. Later the design was officially adopted by the Model Yacht Racing Association of America, and the greatest model yacht building boom ever seen in this country was under way. Clubs and trophies began to appear as if by magic, and at the present time the most sought-after trophy is the ‘Marblehead Perpetual Challenge Cup’ which was won this year by the Jersey City Model Yacht Club. The Heisler Cup, which was given by Mr. Charles Heisler of Rensselaer, N.Y., is another beautiful prize. This cup is held by the Red Bank Model Yacht Club. Another trophy, a sterling silver bowl, which was won last year by Mr. Frank Goodwin of the Marblehead Yacht Club, is the Chester I. Campbell Cup, which was given by the estate of the late Chester I. Campbell. The winner of this cup holds it for one year and also receives a replica to keep. There are also large regattas held each year by other clubs at which there will be from 50 to 60 models. One of these events is the National Championship Races of the Marblehead 50/800 class, which will be held this year in Warinanco, New Jersey. Little did anyone who saw the first profile drawing on the old barn door think that it was to be the forerunner of the largest model yacht class in the world today. And now, to make the joy of 50/800 fans complete, I have this week received notice from the Model Sailing Club, a department of the German Sailing Club, that the Marblehead 50/800 class has been accepted in Germany because they ‘…believe that this class will render very nice and useful boats with a simple formula which are not difficult to build and which besides the reason of their small size are handy …’ An accompanying notice gave word that they are to hold an International Race at Hamburg at the end of the Olympic Games. One of the two yacht classes selected for the race is the Marblehead 50/800, and this country will be invited to send two boats to the competition. Eight other countries have also been invited to participate. From the small beginning on the old barn door has come the most popular class of yachts the world has ever known; after blanketing our country, it has spread to foreign lands, and is still growing.

In 1932, the Marblehead club issued a challenge for M class boats, and Cypher was the successful defender. She is typical of “first generation” M boats in that she has a fair amount of overhang at bow and stern and thus retains a “yacht-like” appearance. This was all to change rapidly under the pressure of competition.

Cheerio I .

rc marblehead yacht

John Black and Cheerio I on the dock at Hamburg in 1936.

John Black’s Cheerio I won the first international M class race held in Berlin in conjunction with 1936 Olympics. The design is interesting in that it attempts to maximize waterline length and still maintain a shape reminiscent of her bigger sisters.

Cheerio later became famous with the publication of Black’s 1939 textbook Yachting with Models , and many copies of her were made. By that time, however, the design was no longer competitive; the snub nosed, vane-steered, high-rigged boats had come on the scene.

A. R. Lassel’s Sun-Kiss dominated the races of the 1940s. She was an example of what could be called the “third generation” of M boats. All pretense of “yacht-like” lines is gone, and the waterline length is carried as far as the rules will allow.

Here is her designer’s description, which accompanied the publication of her plans in Model Yachting Monthly for September of 1945:

The “Sun-Kiss” design shown in the MYM supplement stems from “Faithful” and “Gurgles”, The 1937 and the 1941 National M-Class champions, and from “Roschana”, runner-up in 1937. Ted Thorsen re-drew the lines of these yachts to conform to those of warships having a speed that produces the constant 1 in the speed-length formula. Hence, an M-Class yacht should make 2.04 naut. miles per hour when a 500′ warship makes 22.5.
She is not giving away any potentialities due to water-line length, has powerful sections and a flat chine line. Her lateral plane is more than adequate, so that, if wetted area be considered more important than dynamic balance, the width of the skeg may be reduced. On the “Sunmaid”, the last year’s National Champion, the skeg is a mere strut. The keels of Paul Collet’s “Sunmaid” and How’d Curry’s “Sunapee” weigh 13 lbs. and J. McKinney’s “Vagabond” and Dr. Peal’s models from this design weigh 13.5.
The design of the keel is the result of an observed phenomenon in towing 50-inch models of different keel designs at about twice the normal speed. When the junction of the keel with the hull was rather thick, and the yacht towed with a decided heel, the resistance as compared with that of the upright position, shot up eight-fold. The only visual difference was a short but steep secondary wave in the way of the keel. The obligation, then, became the elimination of this secondary wave; the seal-flipper keel as shown on “Sun-Kiss” represents an effort in that direction. The scope of the sliding rig is sufficient within the range of 0 to 18 mile winds.

Sun-Kiss was a West Coast boat and was raced on artificial ponds that were deep and generally right on the shore where the wind blew straight, hard, and often. Back in Marblehead itself, the boats raced on historic Redd’s Pond: a natural venue of great beauty, the occasional submerged rock, and notoriously fickle winds. J. Selmer-Larson’s Broom V , a contemporary of Sun-Kiss , shows how this difference in environment affected the design. Note the shallower draft and hull shape tailored to lighter airs than those of California and Washington state.

Arrow III .

Ains Ballantyne was a New Zealander who took his love of sailing to his adopted country and designed and skippered many successful boats on Redd’s Pond. He was a pioneer in vane gear design as well. This boat represents a synthesis of the West Coast “seal flipper” school and the shallower draft boats of Selmer-Larson. The rig, though conservative in height, reflected a deeper understanding of the optimum ratio of jib to mainsail.

Ted Houk of Seattle was one of the most innovative designers in the class; his Humptulips strongly influenced the design of Sun-Kiss . In 1949 he came up with Rip Tide , which may be the pinnacle of design of the free-sailing era of M boats. The deeper draft takes advantage of the West Coast ponds and permits the carrying of full sails in anything less than gale winds. Note the elegant hull shape, with its hollow (concave) entry transitioning to a flat, semi-planing floor in the aft sections. The construction was equally impressive for a wooden boat: 18.5 pounds displacement, 13.5 of it in the lead keel.

Warrior I .

Because there was no general-circulation journal covering model yachting in the 1950s and 1960s, we have an almost complete lack of plans from that period. (This unfortunately poor-quality scan is from a copy of builder’s plans.) By 1971 we do know that there were two organizations competing for the right to sanction international model yachting races in the United States: the Model Yacht Racing Association of America, which focused on free-sailing boats, and the then-upstart American Model Yacht Racing Association, which promoted radio control. In 1971 each of them held championships, and Stan Goodwin of Marblehead won both with this boat. As a single design which triumphed both in free-sail and radio control, Warrior I marks a fitting transition from the Vintage to the Modern Era.
