Deck to hull joint
Interesting diagram. If the boat had actually been constructed that way, there might be no problem. Maybe some boats were actually constructed that way, but mine was not. On my boat (1973 E 35 II, not sure of hull #) there exists nothing at all such as that which is labeled “Deck to hull Bond” on the inside. In the diagram labeled “seam fill” one might think this would be some kind of resin putty, but it is not. What exists at that location is a piece of soft wood (looks like pine or fir on my boat). It was about 1.5” wide (tall) and maybe 1” thick (deep). The width of the hull at that point is about 1/2” and the folded over Lips of the deck and hull (which are shown in the diagram) stuck out about 1/2”. There was absolutely NOTHING attaching the deck section to the hull section except this piece of wood that was glued at the top and bottom to the deck and hull. On my boat in several places this piece of wood had voids in it. One could see daylight through the voids when the rub rail was removed. It was easiest to see in the chain locker forward, in the starboard side cockpit locker and in the lazarette locker. When I removed the rub rail I noticed the voids, so I inspected inside and made this discover. Noticing that this was a serious flaw and weakeness int he hull construction, I removed the interior of the boat, added layers of FG cloth and epoxy on hte inside, thus installing the “deck to hull bond” as show in the diagram that had previously bee absent, and cut off the lips of the hul on the outside and similarly added FG with epoxy, making the deck to hull joint integral and structural as well as much better looking. Maybe smoe, most or even all of you have hulls bonded to the deck as in the diagram, but I assure you mine was not. If mine was not then perhaps others were not also. Might be worth looking into. I would be curious what other E35 owners discover on closer inspection.
