Dart Hawk is a 18 ′ 0 ″ / 5.5 m catamaran sailboat designed by Reg White and Yves Loday and built by Dart Sailboats starting in 1996.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

The Dart Hawk was designed to the Formula 18 rule (written by the designer). Spinnaker: 21m2.

Formula 18, the sports catamaran for development

Formula 18 (or F18) is a class of sport catamarans defined in a "boxing rule". This rule sets eligibility criteria (max/min) such as width, length, weight, sail area, mast height and materials to be used .

The class measurement certificates for the boats in the class can be consulted online at www.f18.fr, they allow everyone to check that the material offered conforms to the description given by the class. This approval, a sort of quality control for the practitioner, is carried out by a national network of measurers who ensure the certification of new equipment whether it comes from a shipyard or an amateur builder.

Formula 18, sale and second-hand market

There are second-hand Formula 18s for every budget, from the thrill ride to the superb opportunities to tease the podiums. Main brands and models on the market: Nacra, Goodall, Hobie Wild Cat, Cirrus (BCM), Bimare, Mattia, Diam, Alado, Shockwave...

Let customers speak for us

Just brilliant, exactly what I needed and good quality. Fits perfectly. Fast delivery and usual great service. Thank you, highly recommended

I use this tape to repair waterproof jackets and it is as strong and waterproof as many other alternatives and much cheaper :)

This cover fits easily over the boat with masts and boom placed on a set of spar holders. There is a neat velco opening to bring out a bowline to secure to the trolley.

A new innovation surprise is having clips on both sides of the cover. You can unclip from whichever side you are on.

Sailing Chandlery have listened to feedback from a previous purchase of the older design. Remains to be seen how it weathers, how breathable and water-proof it all is, but looking v smart from new.

Probably the most comfortable visor I’ve worn. I put it to the test in Dubai last week, it never budged, and wasn’t too tight or hot. The little clip gives added reassurance that you won’t loose it. I’m very pleased with the purchase.

There’s a reason I keep on buying these. My last pair lasted 4 years of use, sailing almost every weekend. They last and when you consider the cost and use, it probably works out to be the equivalent of buying a really cheap pair once every 6-12 months. Why buy twice? Very comfortable and supportive.

What more can be said, easy to fit and do the job

Very happy with the Kingfisher braid on braid, very easy to splice.

Great top, fits perfectly. I’m purchased a size 10 and is true to size.

I am very happy with my products . The advice on the kicking strap replacement rope was very helpful. Love thee we colour and material of the Velcro strap. Thank you 🙏

Needed floating cleats to secure a freestanding mast middle of RIB. Ideal adjustable guy system created using these.

As expected at a good price with fast delivery

This is a top quality rope, a bit stiffer on hands than polyester braind on braid but much lighter for the same breaking load, I bought it for sheets on a light air sail. It is perfect for the job.

Massive thanks to Andrew and team. The boat was immaculate, stiff hull and package of new kit. Asked whether we could collect the boat between Christmas and New Year en-route to an event and the Sailing Chandlery team couldn’t have done more to help. Thank you.

Thanks they look great but I haven’t put them on yet!

Dart Hawk 18 F1 Catamaran

This is a Dart Hawk Catermaran sail number 858.  5.5M long. It is being sold by Teignmouth Yacht Club. It was donated to the club to raise funds for a new safety boat. It was brought into the country by its previous owner from Switzerland.

As far as we know it was sailed on a fresh water lake. The sails are as new. They look and feel as though they have never been used. The running rigging is all top quality Harken and also looks unused. The boat is in excellent all round condition with only a few minor signs of wear.

The boat has not been on the water since it was brought into this country. There is no Trailer or launching trolley with this boat. Bidders are advised to look the boat over. This can be done by arrangement. I have more pics if required.

We can help with delivery. The boat was transported here dismantled. The only parts we have not found are the jib and spinnaker sheets. Payment should be £100 deposit by whatever means and the balance on collection which can be cash or direct transfer to the club. More info from phoneOn 17-Feb-17 at 08:56:53 GMT, seller added the following information: In answer to a question about signs of wear are - Small area of gelcoat damage on top rear of one hull, easily repared.

Very small area of gelcoat damage to the side of one bow again very minor Some very small chips to laeding edge of rudders  Small dent at bottom of mast These defect are most likely caused during transport and or storage as the boat clearly has had little use.

For the first time Rosatom Fuel Division supplied fresh nuclear fuel to the world’s only floating nuclear cogeneration plant in the Arctic

The fuel was supplied to the northernmost town of Russia along the Northern Sea Route.

The first in the history of the power plant refueling, that is, the replacement of spent nuclear fuel with fresh one, is planned to begin before 2024. The manufacturer of nuclear fuel for all Russian nuclear icebreakers, as well as the Akademik Lomonosov FNPP, is Machinery Manufacturing Plant, Joint-Stock Company (MSZ JSC), a company of Rosatom Fuel Company TVEL that is based in Elektrostal, Moscow Region.

The FNPP includes two KLT-40S reactors of the icebreaking type. Unlike convenient ground-based large reactors (that require partial replacement of fuel rods once every 12-18 months), in the case of these reactors, the refueling takes place once every few years and includes unloading of the entire reactor core and loading of fresh fuel into the reactor.

The cores of KLT-40 reactors of the Akademik Lomonosov floating power unit have a number of advantages compared to the reference ones: a cassette core was used for the first time in the history of the unit, which made it possible to increase the fuel energy resource to 3-3.5 years between refuelings, and also reduce the fuel component of the electricity cost by one and a half times. The FNPP operating experience formed the basis for the designs of reactors for nuclear icebreakers of the newest series 22220. Three such icebreakers have been launched by now.

For the first time the power units of the Akademik Lomonosov floating nuclear power plant were connected to the grid in December 2019, and put into commercial operation in May 2020. The supply of nuclear fuel from Elektrostal to Pevek and its loading into the second reactor is planned for 2024. The total power of the Akademik Lomonosov FNPP, supplied to the coastal grid of Pevek without thermal energy consumption on shore, is about 76 MW, being about 44 MW in the maximum thermal power supply mode. The FNPP generated 194 million kWh according to the results of 2023. The population of Pevek is just a little more than 4 thousand, while the FNPP has a potential for supplying electricity to a city with a population of up to 100 thousand people. After the FNPP commissioning two goals were achieved. These include first of all the replacement of the retiring capacities of the Bilibino NPP, which has been operating since 1974, as well as the Chaunskaya TPP, which has already been operating for more than 70 years. Secondly, energy is supplied to the main mining companies in western Chukotka in the Chaun-Bilibino energy hub a large ore and metal cluster, including gold mining companies and projects related to the development of the Baimsk ore zone. In September 2023, a 110 kilovolt power transmission line with a length of 490 kilometers was put into operation, connecting the towns of Pevek and Bilibino. The line increased the reliability of energy supply from the FNPP to both Bilibino consumers and mining companies, the largest of which is the Baimsky GOK. The comprehensive development of the Russian Arctic is a national strategic priority. To increase the NSR traffic is of paramount importance for accomplishment of the tasks set in the field of cargo shipping. This logistics corridor is being developed due regular freight voyages, construction of new nuclear-powered icebreakers and modernization of the relevant infrastructure. Rosatom companies are actively involved in this work. Rosatom Fuel Company TVEL (Rosatom Fuel Division) includes companies fabricating nuclear fuel, converting and enriching uranium, manufacturing gas centrifuges, conducting researches and producing designs. As the only nuclear fuel supplier to Russian NPPs, TVEL supplies fuel for a total of 75 power reactors in 15 countries, for research reactors in nine countries, as well as for propulsion reactors of the Russian nuclear fleet. Every sixth power reactor in the world runs on TVEL fuel. Rosatom Fuel Division is the world’s largest producer of enriched uranium and the leader on the global stable isotope market. The Fuel Division is actively developing new businesses in chemistry, metallurgy, energy storage technologies, 3D printing, digital products, and decommissioning of nuclear facilities. TVEL also includes Rosatom integrators for additive technologies and electricity storage systems. Rosenergoatom, Joint-Stock Company is part of Rosatom Electric Power Division and one of the largest companies in the industry acting as an operator of nuclear power plants. It includes, as its branches, 11 operating NPPs, including the FNPP, the Scientific and Technical Center for Emergency Operations at NPPs, Design and Engineering as well as Technological companies. In total, 37 power units with a total installed capacity of over 29.5 GW are in operation at 11 nuclear power plants in Russia. Machinery Manufacturing Plant, Joint-Stock Company (MSZ JSC, Elektrostal) is one of the world’s largest manufacturers of fuel for nuclear power plants. The company produces fuel assemblies for VVER-440, VVER-1000, RBMK-1000, BN-600,800, VK-50, EGP-6; powders and fuel pellets intended for supply to foreign customers. It also produces nuclear fuel for research reactors. The plant belongs to the TVEL Fuel Company of Rosatom.

Rosatom obtained a license for the first land-based SMR in Russia

On April 21, Rosenergoatom obtained a license issued by Rostekhnadzor to construct the Yakutsk land-based SMR in the Ust-Yansky District of the Republic of Sakha (Yakutia).

ROSATOM and FEDC agree to cooperate in the construction of Russia's first onshore SNPP

ROSATOM and FEDC have signed a cooperation agreement to build Russia's first onshore SNPP in Yakutia.

Rosatom develops nuclear fuel for modernized floating power units

Rosatom has completed the development of nuclear fuel for the RITM-200S small modular reactor designed for the upgraded floating power units.
