Boat was a veritable Petri dish!
It seemed there may have been a design issue and some ill conceived modifications / weakening of the structure BUT the biggest failure was glue failure rather than wood fiber failing.That’s what happens when you soak dead wood in water for a while!
The vessel is rigged with inline spreaders.it must have been a damp boat inside looking at all the mould. The moisture content of the timber was also possibly very high leading to glue bonding failures in multiple places. I would like to see where the chainplates are so we can consider the rig forces involved and the bending loads on the hulls leading to the failure.
I think the major problem with wood boats is not the wood but the builder. A couple of simple rules have always worked for me.Yep, and I still think it's perfect for building boats. Wood boatbuilding technology has improved just as fast as any other boat building material. I trust the stuff more than anything else, so stick it!
Thanks Hatter. You are more articulate and polite than I am. I have only built in wood/epoxy and composites, but at this point I'm really in love with plywood, lumber, and epoxy and really sick of composites. I have done most levels of composite work and I've grown to really dislike the materials and the waste generated. The only thing you failed to mention is the very forgiving nature of wood/epoxy from an engineering aspect. Things that shouldn't work can work. Under-engineered or under-built structures can be surprisingly strong and long lasting. I don't pretend to know everything, but I really like wood/epoxy boats.I think the major problem with wood boats is not the wood but the builder. A couple of simple rules have always worked for me.
The wood has to be dry and when the resin is applied the wood needs to be cooling and not warming up unless applying a vacuum. All fixing holes need to be oversized and filled and then re drilled with a smaller drill to keep a healthy layer of thickened epoxy between the moisture and the wood. I also like putting a light layer of glass over it to stop the grain from opening up and letting moisture in on areas exposed to the elements. It is a very easy material to work with and for this reason may attract builders that just don't have the knowledge/experience to do it right.
Don't blame the wood, blame the builder.
