just a note.. Jim Boyer has stated in the past his boats are well made but "rugged" in construction.. Even his fantastic Auscat is probably over built in some respects.. <br>AHPC uses foam core (nomex is lighter) and wet layup (prepreg is lighter) with Al spars and beams.. Lets not forget someone will be bringing out PBO honeycomb cores.. <br>So if good boat building can produce an "A" at 75 kg without HT construction I dont see why the other A class builders and professional yards cant product a 16 at under 100 kg.. <br> <br>The good am builder such as Phil should also squeak in a combo.. Given a set of female molds I would attempt a new 16.. I do know my designer is itching to have a crack at a cat.. <br> <br>Just weighed my home built 11 foot moth hull 7.9 kgs painted.. Now how does one keep these things upright?????...Anyone considering a 11 foot cat class.. Though Im told the foils make these things more stable..Otherwise Im going to add a second hull!!! <br> <br>Stewart the drowned rat.. (who now owns a boat yard)<br><br>
