Review of Ross 930

Basic specs..

The boat is typically equipped with an inboard Yanmar 1GM10 diesel engine at 9.0 hp (6 kW), which gives a max speed about 5.2 knots.

Sailing characteristics

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Ross 930 is 2.19, indicating that this boat would not be accepted to participate in ocean races.

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 6.9 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Ross 930 is about 153 kg/cm, alternatively 856 lbs/inch. Meaning: if you load 153 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 856 lbs cargo on the boat it will sink 1 inch.

Sailing statistics

This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.

Record fleets of Ross 930’s in Auckland

A record of 13 Ross 930’s raced together in their own division on Sunday June 17th, in the Ponsonby Cruising Club Winter Series.   The distinction between standard and modified boats has now been dropped, ensuring larger fleets.  In Sunday’s conditions it was hard to tell the difference between the two types.  All 13 yachts managed to complete the shortened course, and after over three hours racing it was Drop Dead Fred who took out both line and handicap. The resurgence of the class has seen owners enjoying class racing in a very competitive fleet.

The Ross 930 is a cruiser-racer yacht designed by New Zealander Murray Ross. Over 50 boats have been built to this design, most of which are still in New Zealand. It is a relatively light weight boat with a moderate sail area. The bow section is quite narrow, which provides low resistance and reduces pounding while sailing upwind as the stern section is wide and flat for good downwind sailing.

Don't forget to give credit to the broker that took those photo's you are using.....  

The boat does not have a trailer, has a sort of retractable keel without a lock down pin, draws about 6'. She is cold molded with glass/core/glass on the outside of the cedar. Contact me if you need any more info, more then happy to share what I know about the boat.

"Updated Young 88 / Ross 930" Interesting description from someone in the USA.  

looks more like a lidgard 30 , good seaboats but certainly downrated compared to either Y88 or the R930

Thanks for your interest. Dick Johnson is correct, there is not a trailer. Have not raced the boat seriously.  

Boat is a Kennedy 30. Previously on CL

That is a gorgeous boat. Have you done anyhting to upgrade it since you purchased it? Do you have any pics of it under sail?

Nice video on Youtube, was listed by Broker at 14,900 and sold in November 2013! Beautiful boat & very sea friendly layout. But why the increase in cost? My only concern would be the scantlings and quality of construction, but she reflects a lot of care and knowledge. If she had an inboard and I hadn't just put a deposit on a similar boat, I'd be tempted!  

she actually did not sell in November, but was taken out of the brokerage. Fixed...

Ross 930 off shore

Hey, what would a Ross 930 be like off shore doing open water races?

Battleship 100

f*ck'n scary I imagine but a few have done it before, I'm sure rope peddling car wrecker will pipe up sooner or later as he has plans for SR.

Pepe did the last Round North Island and was going well till the backstay failed.

Deep Purple 511

Toyed with the idea of bringing Wild Oats back from Nelson via sea but after talking to a few people decided to truck.

Admittedly as much to do with my lack of experience rather than concerns over the boat.

Plus Tony Harold and Bill Kidman did RNI on Malpractice

Just about any boat can go off offshore if you know it and know how to manage it correctly. You don't really even need to know that, assuming you have a good skill set already, but it would improve your chances of making it to the other side.... of the water knot the pearly gates.

But bureaucracy going out of it's way to do nothing except cover it's own butt and stupid dipshits with misconceptions based on nothing more substantial than the smell of their own turds do and quite often cause many boats to get blocked from doing that. Shame really as those dicks are f**king NZ yachting, sadder still is it very much appears they can't see that.

There is no sound reason a R930 can't go offshore assuming the crew are up for it and the boat's been prepared properly, just like any other boat.

I asked Murray Ross that same question a few years back. His response was something like "of course the 930 can do off shore but not with me on board"

I do recall that mad Frenchman disappearing early one morning on his way to Noumea, single-handed on Blue Dude the Young 8.4 after about 24hrs of prep after purchase. I still think I'd rather go an 8.4 tho - slightly less tippy.

I'll put up a case of Mt Gay that I'll beat ya there

Redline is intending doing the triangle race, Wellington/Akaroa/Napier/Wellinton. Problem I see with smaller boats offshore is that by the time the boat is loaded with the mandatory requirements (extra anchors and warps, liferaft etc) and food, water etc it is well on to being overloaded. Needs careful management.

I wondered who got in before me!

Malpractise sailed to Oz. She's actually up for sale at present.

I'd rather go to sea in a 930 than a lot of other designs. Add a heap of deck beams, brace the windows shrink the main and you are off.

At least with the narrow beam she's less likely to roll.

Yes TimB, the amount of safety gear needed to be carried in some spots is becoming a hazard in it's own right.

* - Pedigree being the old Class boats with baby sails and keels. Under the new rules all 930's are class boats, being the progressive knot living in the 80's class it is.

  I wondered who got in before me!   Well done Sundreamer

I've crossed Cook Strait several times on Airship.

Cook Strait can be a beast of a place - the seas in particular can get very heavy... particularly in the Karori and Terawhiti Rips. The first time I ever went through the Karori rip it was on a Young 11, Flying Circus. We went from 1 metre swells to 5 metre breaking swells in an instant... one completely swamped the boat, almost without warning. I wondered aloud "What the F*** was THAT!?" and was told, oh, that's the start of the rip.

I wouldn't want to hit the rip, or a significant sea way (5 metre plus seas) in a 930. Not if I couldn't turn and run with it instead of going into it.

When we've crossed the Strait on Airship we've watched the weather closely, and picked a window with favourable tide and winds and then just scooted across. No sweat.

But 40+ knots upwind in a seaway is not a fun place to be - pretty much ever, but ESPECIALLY in a small lightweight yacht (like a 930 or similar). If you are racing offshore you're going to need to do those sort of conditions, sooner or later.

The two main factors that would intimidate me are:

( a ) being so light the helm needs constant management in those conditions. An Autohelm is of marginal value - because the boat reacts so dramatically to changes in wave pitch, angle and period and wind direction and strength, it is very tiring being on the helm upwind in 40+ knots for an extended period in a 930. You have to do soooo much thinking and adjusting.

And ( b ) being so light there's a LOT of slamming, a lot of noise, and a lot of shock load variation on the rig and hull and crew. Again, okay for a short time, but two or three days of it would be very very gruelling.

Cruising offshore in a 930 allows you to run or hove to (and yes you CAN hove to racing too). However cruising offhsore the fuel carrying capacity also comes into it.

I do "Coastal offshores" in a 930 - the White Island Race, The Three Kings Race, The Coastal Classic, Wellington to Nelson etc. But transoceanic Offshores (to Fiji/Noumea/ Sydney Hobart) ummm, no thanks.

Interesting comments Bardy.

5mts seas are fine, it's the shorter sharper ones that are the Ahole.

I'd have to totally disagree with your comment (a). They are tame on the helm to windward in a blow and my AP, even the old little slow one, had no problem what so ever going to windward in any conditions. I'd say that's more a function of how the individual boat is set up than the boats in general, as what you describe I just don't see or anything close to it with mine. My AP does little more than stop the tiller flopping side to side and 95% of the time I can aim the boat with one small finger only on the tiller, in almost all weathers, with the boat trimmed to the conditions obviously.

Yes they can slam but it's reasonably easy to tweak out the real worst of it if you want to.

Cruise one offshore? You could but there would be better options. Race one offshore, zero reason why knot.

Any other 930's get what Bardy describes?

My experience is a bit limited in the 930 but I've raced her in 40+ and once in a race where peak measured was 57 (when Recreation got smushed) and the helm has always remained very manageable

I've only used the auto in nice conditions but i'd pick she'd manage just fine.

That said, they are twitchy bastards but that is 90% of the fun! It's the sea state that makes me most nervous though.

Twas pondering Bardys comment on the way to the orifice and I've decided it's more likely the Redline set-up that makes her harder to steer in a blow rather than a general 930 thing. Having sailed a few and thinking about it there is some noticeable differences when holding the steering stick. Squid for example is just as chatty as mine but a lot heavier when wiggling it. Squids blade is a lot different than mine so that could be it and/or overall set-up.

KM will the hull lay-up be OK for cat 1?

“ I just received my asymmetrical spinnaker, with sock and turtle bag, along with a new 135 Genoa. The entire process was simple and both sales and the design team were in regular contact if there were any questions. The customer portal was easy to use and lets you keep track of where in the process your sails are. Great sails, great service -Graham Edwards (Facebook)

“ The whole team at Precision Sails was fantastic from start to finish. We’ve had a laminate main and genoa made so far and have a spinnaker on the way. They listened carefully to our needs and recommended a great sail cloth. We couldn’t have gotten more bang for our buck! -Noah Regelous (Google)

“ We received our spinnaker and launched it yesterday and I just wanted to let you know how pleased we are with it. The service we received from your company was exceptional and the quality of your product is second to none. We will certainly be return customers in the next few months to replace our main and jib sails and will recommend your company to all our sailing buddies. Once again-thank you.” -Daniel Jackson (Google)

“ we had good communication during the planning stages and the knowledgeable people at precision sails really got me fixed up good! The sails look and work fabulous! my boat sails better than it ever had! couldn’t be more pleased with the product AND the service!” -Fred Jelich (Facebook)

“ Our new furling jib for a Corsair 27 Had to be specially designed due to the height of the furler, but this was accomplished quickly and in short order we had our sail which fits beautifully and has a great shape. It’s everything we could have wanted, high tech design, thoughtfully executed and affordable.” -Nancy Y. (Yelp)
