On The Diet - Part 3

Finn Shop
Having achieved a theoretical weight saving of 6.5 kg& so far, other areas where weight savings were explored and with the attitude that every little bit helps, it doesn't take long for another kilo or so to disappear.

Example being the bow stainless fittings to anchor the boom bungy cord. Replaced with custom alloy fitting that enabled the bungy cord to be adjustable (not required in windy days) plus have  a simple rope as the towing eye.

When filling and fairing the new light weight decks it would have been very easy to increase weight just to get the super smooth and furniture grade finish. The Finn is a racing machine not a piece of art, dings and bangs are going to mar the surface with hard racing so why finish it to the nth degree.

To save weight, time and effort simply left the decks in a repectable finish and applied a low sheen paint finish. Bonus is the low sheen will be better on sunny days with its low reflective index.

Coating used was the much revered Resene Durapox Two Pack Epoxy Coating. Simply rolled two coats on using a small foam roller (wet on tacky) and called it finished.  Used on Americas Cup boats so is good stuff.

Touch dry in 2 hours hard in 24.  No need for multiple undercoats and gloss polyurethane topcoats.  Available in any colour. I only used the standard grey and white.  Used four parts white to 1 part grey on the decks and straight grey in the cockpit.  Cheaper to at only $60.00 per litre compared with $120 odd for two pot polyurethane.  Repairs are simple.

With the theoretical weight well down below the limit, the damaged areas on the hull were only recoated.  Did a bit of a graphic paint job just to be different. Again it was really simple, mask and roll.  Sanded the bottom with 400 then 800 grit wet and dry.  Now for the weigh in and the swing test to bring her back up to legal.

Places where more weight can be lost

1-...  Hull coating system where five coats of polyurethane paint protect and fairs the fibreglass hull. Easily replaced with two coats of the magic Durapox. Weight saving of about 1kg.

2-.... Transom can be lightened like the decks. There are enough scantelings built in during the first rebuilt to support the rudder gudgeons. Possible .5kg weight saving.

3-.... Centreboard is full size and weight. Could quite easily cut a holes in the top section and loose possibly another 1 kg.
