Ok so after the RA2014 trip, all the rubber sections under our tubes was hanging off after SIT had stripped it off and realise it. Weren't happy with the work, they offered to re do it, we said no thanks, they've offers no recompense saying that's the trouble with adhesion on old boats. They never told us it may happen. Can't be bothered with them any more.
Anyways, had it all stripped off and a second layer of hypalon put on in black. Looks mint and had a first blast today, we've regained the top speed and throttle response and smashed our previous record. We nailed 53.7mph on the GPS with about a small tide with us. Very happy. Less weight and drag. Mint.
