Catboat#6

Progress on the gluing up of Lifts. I'm glad I have enough bar clamps. The first stage of the gluing I attempted to keep the lifts from slipping just by gluing blocks at the seams. Being impatient to get going with the gluing, (should a used CA) I didn't wait long enough for the glue that was holding the blocks to set long enough. Murphy's law, what can happen will happen: they popped off during the glue up, resulting in a slightly miss-aligned glue job. This is easily corrected during the carving, and I only think of the original lines as a departure point, as long as the end result is lump-free, sturdy, and water-tight. The human eye is capable of detecting the slightest defect in the shape of the boat, which can then be sculpted away.

Catboat #5

I made one or two mistakes, but managed to get the lifts cut out. I think it will be rather tricky to line them all up accurately before gluing because if you make a small mistake between the alignment of two of them, the alignment of the next one after that will be potentially even farther off. I did try something new. I marked not only the vertical section lines, but also the horizontal water line to help line things up in all directions. For one of the lifts I cut the cut-away all the way aft past the stern, instead of up to the sheer. I'm going to have to fill that in with an additional little block of wood.

I cant wait to get it carved up so I can test float it with a CR-914 keel bulb. She's pretty short ended but definitely wide, so the 3 1/2 pound bulb might work which would be great. The conservative sail plan I drew is about 440 square inches, and the CR-914 is about 580 square inches, so maybe something in the range of 500 square inches would work pretty good. That high bow with all its reserve buoyancy will be fun to watch.

Catboat #4

Okay, so after much head scratching, I decided to nix the idea of making it (her) a planked model. I've drawn up the lifts to carve the hull. Here's the lines plan. I've traced the lifts (not shown) onto the wood.


  I really like the character of this boat. I wanted to make something unique. Its fun to visualize that High straight bow, plowing into the waves.

Catboat#3


Ive decided to design the cabin and hull to be built all in one piece on the strong-back.  This is sort-of a new Idea I haven't tried. I think It will simplify construction somewhat, plus allow me to get the vertical cabin sides I want. Perhaps there will be a cabin floor, at bottom level of cabin sides a bit under the deck, extending aft in one piece to the aft end of the cockpit, level with waterline. This will also be a good place to install winch and rudder servos.

Catboat#2

here's some renders of the catboat I'm fooling around with.. Definitely going to be a worthwhile challenge


here's the drawing it came from


the part where the deck meets the side of the cabin is keeping me up at night,
in a good way. I would like the sides of the cabin to be plum vertical despite how much bend there is in the plan view. Either make a jig of some sort, and hot bend some thin stuff around the jig, then fit to the deck, or use vertical "staves" like the real catboat. Hmmm..

Catboat #1

I am going to try to give a blow-by-blow of the construction of my next project, a Fenwick Williams
catboat. I will be working from plans which I began to adapt from a
Lines drawing in “The catboat book” a few years ago. I love catboats, not just for their
Unique sculptural qualities, but also I grew up sailing in one with my Dad.

I look forward to figuring out how to build the curved cabin sides, as well as frames and planking.
I haven’t done a planked model since the “Mellonseed Skiff” a few years ago. Another
Interesting decision is how much to reduce the sail plan proportionally. For a 32 inch catboat model, a full sized sail (proportionally speaking) works out to something like 800 square inches.

Here is a pic of the other Catboat that I made

Is there more to life than boats? Duchamp was afraid of repeating himself. The other day I took a picture of a Praying Mantis bug that was right by the staff entrance to the Museum. He was standing at eye level as people walked by him. I said to my Supervisor “Did you see that Praying Mantis?” He had already taken a picture of it.

Hard to beat nature itself when it comes to sculpture.
