Re: Irwin - Bluewater Capable???
Just a note on the hull deck joint. I really think the deck joint is where Irwin gets its bad wrap. Irwin used screws (yes screws) instead of bolts to mechanicaly fasten the the joint and the screws come into the joint from the side as well as the top. When these boats were newer the joint was actually fantastically strong, in fact Irwin was very proud of their hull deck joint, even diagraming it in the sales brochure. The fact is after 30 years these screws have likely suffered crevice corrsosion and could be dangerous. Through bolting the flange all the way through the block is the best idea, but will require a significant refit, as much of the joint is not accessable and requires replacing interior wood work.
The hull deck joint uses an overlaping flange that is chemically bonded, the flange on the bottom wraps and compelely incapsulates a solid ash block the full length of the joint. (Very strong) Holes are drilled through the flange and into the ash block to support the stantions and the ash was epoxy sealed and then adhesive was used to secure the stantion in the block. The whole joint was excellent when these boats were newer, but with water intrusion from lack of maitenance, the ash block around the stantions begins rotting and then the stantion is no longer strong. These are not difficult fixes, but will require some effort. The hull next to the joint is solid glass and there is no core, which means even with water intrusion from the joint, or the stantions, there should be NO core rot in the cored area, as there is no way for the water to get there.

Reason: lef out the word NO in front of core rot.
