How did this happen Adriano?
Hard to explain in english but I'll try....
I probably build the beam too sharp... the piece of wood under the beam had not enough space to move as they sholud...
I don't know if I could explain, but I would like to have yours opinion
there were bolts, but they were rusted. We are noe working on it. Original plans suggest only epox or even bolts.
Anyway don't you think it souldn't happen anyway even with bumpy waves?
My failure was due to loose lashings and waves in a massive squall pushed the boat into the pier so lot of lateral force on beams (tied to end of pier). I put two 3.5" long and 1/4" width stainless screws down into them. I countersank the screws and filled in the top with epoxy. I wouldn't be against adding another screw to each socket. Due to the location of the beam blocks on the 21, I don't know if you could get a washer and nut underneath as mine are directly over the sheer stringers. That's why I just went with some big screws. Haven't had an issue since, but I have since frapped with Dyneema. I tied a clove hitch to a screwdriver and really crank the shit out of each turn on the frappings. Solid as a rock now!
