I recently purchased a RS200. I haven't sailed it yet but I'm enjoying the bimbling to get it ready.......Recently there's been some boat weighing at the club, this was prompted by the variation in 2000 hull weights (our 2k sailors being uber competitive). Anyway long story short I thought I'd weigh the 200 hull c/w center board to see how it compaired with the RS published figure of 78 kgs Confused

.......it weighed nearly 90.

I rang RS and they told me the 78 kg figure is for an unfitted hull, fitted it should weight 88-91 kgs.

So why publish the unfitted figure? a useless figure surely. What is the point?

Are all published hull weights unfitted weights?

Most hull weights are published fitted with sheets and centreboard/daggerboard in my experience. It depends on the class though.
Needs to sail more...

Thats a very good question.  Its a bit like the MPG figures car manufacturers publish.  My car has a marketed combined figure of 53.3MPG.  I mainly do motorway miles and due to previous run ins with the law i drive a very sensible speed and struggle to get 47mpg. 
 
I do however agree, why publise the bare hull weight for an SMOD?  Not sure how Devoti do it mind you, it could be the same way.

If one were being cynical one might suggest that it enables a lower published figure, but if you consider factory QA procedures then I reckon "just out of the moulds" is the best time to do the weighing: especially if you are going to discard any boats that have come out too light or too heavy.
With rule controlled classes its normal to have a "a stripped of all loose gear" figure for weight because it makes check weighing at Champs easier.

Finns are generally down to weight and the distribution of the weight is controlled with a gyration test, the average finnster is also very keen to know that their boat is right up against the gyration minimum parameter, so when the minimum weight was reduced by 3kg, it wasn't always possible to get down to the new weight by removing lead (due to it's distribution) and still have the boat swing properlywithin the class rules.

12kgs of fittings, what are they made of lead?

Something still does not add up.

That's what I thought: i.e. Enterpise  @ 94 kgs......Now you know that a RS200 weighs nearly the same.


When I rang on a Saturday morning the bloke who answered gave the info quite freely and promptly.....After chatting about it later with mates I started to have doubts, I thought maybe he had picked up the 400 spec sheet by accident. So I rang back during the week and spoke to the regular sales guy. When I asked for the fitted hull weight he couldn't answer and went to the shop floor to find out, he rang back and confirmed that the 200 fitted hull weight was 88-91 kgs.

Jim, from a QC point of view it would make sense to weigh them all unfitted....But I can also see it from a marketing point of view. Call me a cynic.  

From a class racing point of view it doesn't make any difference, after all we're all in the same boat. But from an old fart with a bad back point of view it's very important when dragging the soddin' thing around on shingle Ouch

The phantom hull weight is as per jims comment. All loose rope, rudder, mast and boom are removed, the rest is weighed and must be no less than 61kgs. If less then upto 3kgs of correctors can be fitted.

As for the 200 I guess that the all up weight includes the mast, boards, pole and other fittings so I reckon that would soon mount up
Everything I say is my opinion, honest

Well that is one definition of hull weight, but the 200 is a simple boat, I doubt there are 12kgs of fittings on a Merlin, where is the rest of the weight?

What we really need to know is the all up weight of the boat, rig, sails etc ... that is what impact performance and ease of handling on the beach.

Something still does not add up.

Fittings include: centre board, blocks, cleats, toe straps, bungee, hatches, bowsprite, spinny shute, shroud plates, screws rope and stickers + several short curly hairs that I found in mine Tongue
