One final comment on the paint. Compared to the usual marine paints Rustoleum is much cheaper but also offers a more limited choice of colors and it would appear that it is not designed to be used as a mixing base to make your own color.
I let her get good and dry and then flipped her over onto a nice soft cloth pad to protect the paint. The frames were still attached and were the way I supported the boat while painting. Now for the first time I got a good look at the inside of the boat. WOW! I had a lot of finishing to do. This included filling screw holes but mainly if was filling in and making filets were the chines, keelson etc. did not seal as tightly as I would have liked. From a functional standpoint the boat was sealed. From and esthetic one I had a lot of work ahead of me. Since the epoxy is pricey I mixed up just enough so I knew that there would be no waste. This was your peanut butter consistency and applied with a tongue depressor went on easily and gave a nice effect. I would give a piece of advice when doing this. Wipe off the excess with a vinegar soaked cloth as soon as you are finished with an area. It is a heck of a lot easier than sanding this rock hard stuff once it dries.
I still had the frame legs uncut. The center ones in particular were a real nuisance to work around so I cut them off almost to where they will be finally but since I still have work to do on the sheer as far as trimming off the plywood I left a few inches that will come off later. Now I at least wasnt catching myself on this stick that was serving no purpose. The bow and stern legs werent nearly the problem and I still havent touched them. I went off the CABBS plans for the mast step and thwart. I saw in someones plans that they had enclosed this part and made a buoyancy box out of it. I used ¼ maranti for the top which I fitted up tight to the underside of the inwales. Put a few cleats along the sides and fore piece to hold it tight. I then scribed a pattern on cheap plywood for the vertical piece. For this I used ½ maranti figuring that this would be extra cross bracing since I am using ½ plywood instead of the ¾ per plans. I will cut a 2 3/8 hole at the point 11 back from the bow and into this will go a piece of 2 PVC. When finished it will be sealed with epoxy.
What I havent got straight (so to speak) yet is the rake of the mast and exactly how the step will be angled. The mast will be reinforced 1 ½ PVC. From what I can tell, and Kyle Leonard has said, the mast should be perpendicular to the sheer line That is what I finally did. I took a piece of 1x4 sprude, used a 2 3/8 hole saw an cut completely though it and attached it to the keelson in just the right position so that the 2 pPVC would be perpendicular to the sheer line. Not as difficult as it may sound. Used epoxy to fasten it. I put in a 4 water tight inspection port in the vertical piece a little off center so that the area may be used to store a towel etc. I will have pictures of all this. The port cover is frm West Marine and cost less than $10. Really happy with it. As looked at the inside of the bow transom it just looked unfinished so I took a piece of 1x4 spruce, as clear as I could find, and scribed a piece to fit on the inside of the bow on top of the mast thwart. I think it looks pretty good. I am doing the same on the stern with the exception that there will be a perpendicular piece running down to the keelson. Since the gugeons will attach here the added strength makes sense. BUT all this trim work adds weight to the boat so for those wanting the lightest craft possible all this is not for you.
