    Posted: 29 Sep 19 at 5:05pm
My Miles built Solo is 70 kilo on the current certificate with no correctors.

I would like to reduce hull weight to allow for correctors to be fitted, and to allow for the class discussed possible reduction of overall weight by 3 kilo.

My boat is due a re paint so can remove any excess paint layers. I am intending to change the existing keelband metal trim with plastic. My transom flaps are already thin gauge plastic.

Any other ideas or suggestions ?

Wait to see if they adopt a new rule about centreboard capping.

Are Solos weighed with the board in or out?

I'd be amazed if you lost 3kg in paint. Keelband too is probably Aluminium as as light as you'll get.

I dont think theres much excess wood that can come out either!

And, being realistic, how much difference in performance do you expect 3kg to make?

Board out. Perhaps when I take my boat in to my superb (!) repair and spray shop next month they will have some scales! ( Chris) to check out what I am chasing.

Taking the "coffee table" out is an option, but losing it as a grab handle after capsize and as a steady to avoid capsizing anyway on a wild reach balances the loss of weight.And it looks like any rule change wont be agreed till, next summer anyway

You are completely right, but it's the same mindset that gets us buying new sails when the existing are ok.

I just like to know when be beaten by someone, it's me and not my kit

I suspect that the best way to lose 3kg from a wooden hull is to strip off the paint & varnish, then keep it warm & dry for the winter.
Re-paint & varnish before use.

I've got a similar problem - the measurement certificate shows a hull weight of 70kg (without correctors), and 3kg of correctors required...
I suspect that the original measurement form didn't get processed correctly.
My only recourse now is to have the hull remeasured.

I also note that Tony Thresher has been fitting a second floor in a number of older Solos. This is reported to increase boat speed due to greater rigidity of the floor.

Thanks Colin my boat had the double floor fitted from new, and without doubt it improves speed. The difference between a wooden double floor and an frp seems most pronounced in marginal planing conditions where I am assuming extra weight hurts most. Who knows? perhaps the Solo assoc will remember there are a lot of boats without or with few correctors and cancel the proposal to reduce all up weight? But will continue with my attempts to get weight down and some correctors into 4217
