New Dufour 34
This hull-deck issue is really confusing. I noticed that (if I understand it correctly) the Aerodyne yachts (considered quality yachts) don''t have any screws or bolts through the joint - its "bonded" only with modern material.
The Dufour has Sikaflex for this, with an integrated glassed in wood liner and then two layers of screws as mentioned above.
Are bolts really always better? How many boats have bolts that have worked themself loose, thereby not actually giving any structural support? Screws could be better as far as that is concerned.
It is likely that this whole issue is blown out of proportion. Isn''t it more likely that something else will fail completely in bad wheather (like the crew), before the hull-deck joint fails on almost all boats, no matter how it was put together?
