Well I wasn't referring to the 200, just generalising as is often the norm for me, fact is the one I referred to was a double kicker main assembly from Harken including the block which was certainly a kilo if it wasn't actually the 2 my natural tendency to exageration might have claimed.
However it still serves to highlight why only the bare hull weight gets published, if I chose to spec mine with a proper man bit and you used your girly one there is immediately a weight difference.

So when buying a secondhand boat... how many people weigh it?

Found this on the Musto website:


It would be helpful if other companies did this rather than their own misleading definitions of "hull weight" ... this way you know what you are getting.

Given that almost all the 2nd hand boats I've bought have dated back to the 70's or earlier, weighing them would be the least of my worries...

Having said that, the ancient GRP Solo I bought a while back left a huge groove in the water rather than planing and took 4 strong people to lift it. Suspect it wasn't very near min weight...

The equally old Lightning I replaced it with is barely heavier than a new one.

Seeing as we are discussing the discrepancy between the actual and published hull weight of the RS200 I don't see what relevance the weight of the fitting on your Alto has ... but just to keep to the facts.

The Harken  Duocam Cam Base — Swivel is 454g and a ratchet block is 85g so a total of 539g ... 

"natural tendency to exageration" ... that is one phase for it ...

I weighed a new boat when I had one (a Lark, years ago) before taking delivery. Now I have a 300, I've no idea how much it weighs and prefer not to know - just go out and sail it - the guy next to me may weigh +/- 10 kilos than me anyway.

I suppose some classes are more weigh critical but it's easy enough to do so I see no reason not to, just out of curiosity........2 sets of bathroom scales, 1 under the bow, 1 under the stern, add the 2 weights together. While it's in the garage over winter, might as well.

Surprisingly inaccurate. Bathroom scales are often very poor at accurately measuring things that are not standing absolutely square on them. I gave up doing that a long time ago because the results were useless. Maybe there are modern digital wotsit bathroom scales which are more reliable, but if the figure changes if you rock about between toes and heels then don't bother trying.

2 years ago I attended a Finn reweighing / reswing testing session in New Orleans, some of the guys couldn't get the full 3kg of lead out of their boats and pass gyration testing, they were definitely selling for less than 2% of the hull weight!

Indeed, that's why I put wooden blocks and padding between the boat and scales to make sure the weight was centred on the scales........adjusted the weight to 0 with blocks on scales. Then did it 2 or 3 times, same weight each time.


.....and I suspect it depends what sort of accuracy you're after. I wouldn't be happy if this method was used at a class weighing session and got a DSQ
