Tom, you mention in your last post that you are starting on a 14' single. Any progress to report? I do hope so.
A materials list to begin sourcing here in the UK would be great to be working on whilst the design is worked up.
I've finished the skinning frame, and have all the materials needed, but have not yet started skinning the boat. I hope to
get going on it in the next week or so. Then it will be no time till it's completed. I've been sidetracked with another project.
Materials list.... As long as you are aware that all is subject to minor changes, see below. Also, the list is likely not complete,
but the best I can do so early in the morning. I reckon it's enough to get you started. Plans / instructions will be available
after completion and testing. It's best to buy more tubing than specified.
Keel.. Aluminum tubing
1. 1ea X 1" X 9' center piece divided into 3ea X 3' sections. A 12' center keel is also possible.
The 15.5' double did fine with just a 10' X 1" center keel section.
2. Inserts for keel center piece are 4ea X 7/8" X 6"
3. Stems are 2ea X 3/4" X 3.5' before bending and trimming
Chines.. Aluminum tubing
1. 2ea X 3/4" X 15' ( divided into 3ft sections ) before trimming length to approx 14' each. I plan to go with
2 chines ( side stringers) initially, and add 2 more if needed. (See Note 1 below)
2. Inserts for chines are 8ea X 5/8" X 6" or double that if using 4 chines.
Cross Braces.. Aluminum Tubing
1. 2ea X 3/4" X 3ft before trimming ( 4ea for 4 chines)
2. hinges... made from 1/16" X 3ft aluminum plate. The exact process will be in the instructions.
1. 2ea X 1/2" X 6ft before bending / trimming
2. Inserts... 2ea X 3/8"X 6"
1. 6 linear yards (18oz hull) and 6 linear yards ( 10oz deck) A linear yard
is usually 61" X 36"US
1. 6 linear yards of 4oz ripstop or coated nylon
2. 10oz PVC from left over deck skin to serve as glueable backing for the sleeves
1. 1/8" medium length
On this 3 sponson per side design, the chine is inserted between the bottom and middle sponson.
A second set of chines may be added between the middle and top sponson as on the Sonnet Combi double. I don't feel
the additional chine will be necessary on a single based on my experience with the Sonnet 14 and 16, but it may be
useful in certain situations. I'll know more when testing the boat. The top sponson's alone will add rigidity and most
of all greater depth ( 10 inches overall ) vs the 4 sponson Sonnets.
The fewer parts the better for assembly, transport, weight, and cost..... Keep it simple !
I'll add to and / or correct the materials list as it comes to me
