While the boat is upside down, I finished the underside of the cabin top and the aft side of BH#3.The first step was to sand all areas to be varnished. I also taped off the area where I will be mounting backer plates. I contemplated over mounting the backer plates before varnishing, but felt I needed to mock it up properly (from the top side) to determine the proper size and placement of the backer blocks. So, I’ll finish these areas later. I like the look of a satin finish. I am using System Three Marine Spar Varnish in satin for all my bright work. Beautiful stuff…well worth the cost.
Ready to flip the boat right side up and place on trailer.
After glassing the hull, I’m now ready to glass the planks. I chose to glass the hull in one piece, followed by plank 1 & 2. The plans only call for plank 1 to be glassed, but I had the glass and just felt better about also wrapping plank 2.
With the hull epoxy still green, I laid the plank fiberglass into position (the overlap onto the green hull held things in place). It was just tacky enough to stay put with a light touch.
This was harder than I expected. The plank joints were difficult to get right. Fix the top joint…pull the lower joint…Fix the lower joint…pull the top joint. I finally got a system that worked fairly well, but the joints are not perfect. Some small air bubbles exist. The radius is just too sharp for proper glass adhesion. I plan to sand through these areas to remove any potential future problems with water being trapped behind the glass. The hull chine has 2 layers of glass on all edges. The bow has 4 wraps of glass over the plank 1 joint. I wrapped the glass 1″ over the the plank 2/3 joint.
What I learned:
- The glass takes more epoxy than expected to properly fill the weave (I almost ran out…this would have been disastrous).
- The sides took more time than the hull, due to the lap joint.
- The lap joint didn’t want to lay down properly (there are a few air spots that refused to conform)
- A squeegee is a must to work the lap joint.
I feel a little uncertain as to the proper steps in fairing the hull, Any and all suggestions are welcome.
