Re: CAL 25 - Tweaked Boom, Chainplate Leak - Advice welcome
The prior posters have offered quite good advice.
For the cracked rudder, I would offer to 'test' the integrity for internal damage by drilling (3/8") into the bottom of the rudder structure in order to ascertain for water accumulated inside it. If water is inside, it will drain through that small test hole; and, you can pretty much visualize any problem by noting the color of the water that drains out. The drilling hole can be sealed using simple epoxy and 'touch' of barrier / filled epoxy ... in the spring.
You already have a quite good and well thought out plan. Good luck and best wishes on your project!
