I am the owner and slave to a tough girl another Hartley Tahition stretched in the run .
There are many successfully maintained FC yachts out there and a wealth of experience for advice .
It is re commended that concrete degradation and bingles on FC yachts
be either sandblasted and air chiseled to remove damaged material .
Blast will reveal concrete and steel condition . Weld in new bars and wire gal mesh.
Expose repair on both sides of hull .
the repair with epoxy
resin/ epoxy metal primer to aid adhesion later .
Form up outside of hull repair with light plywood
and tom to slip cradle
From the inside pour / trowell a mix of 1/2 Ltr epoxy resin 1/2 Ltr fine cut sand and 1/4 Ltr cement . Adjust viscosity to suit . Do in multiple pours if necessary - really ugly bog .
THIS STUFF IS STICKY AND AFTER CURE VERY HARD
Ramset Epoxy Grout is also good and easy to handle .
Strip form - Grind - Epoxy/Sand bog to low spots - Grind - Voila
Old heads - owners of multiple FC yachts recommend 3 coats of epoxy to the
blasted hull - followed by either a key coat and antifoul or antifoul direct within 24 Hrs of epoxy cure. Same for inside if possible .
Note that FC yachts dont like water on both sides of uncoated hull for any period or reason -electrolysis is also a problem here . Earth anodes and
fittings underwater .
