I'll ask once more. Does anyone know the thwart seat dimensions on a 1965 or older 13' sport. I also need the side rail dimensions. Please, please, please.

I think this is correct: But check all dimensions in boat first.

Thwart seats (2): 11 1/4" x 53 3/4" x 1" (make from 5/4 phillipine mahogany)

Side hold downs: (2): 4" x 53 7/8" overall length x 7/8" thick (make from 1" nominal phillipine mahogany) The top corners have a 3" radius curve. The aft edge of the driver seat is notched in 7" from aft edge. The front seat is only partially notched in, also 7" from front edge of hold down. The forward edge of the front seat protrudes in front of the hold downs. The console top sits on top of the starboard hold down, and its AFT edge is 18" from the forward edge of the hold down. 1" Holes (or slots 1" high x 3" wide) need to be cut into the starboard hold down for the mechanical steering cables to pass through.

The console top is 16 1/4" wide, 12" deep (front to back), and of 5/4 material (1" actual) thickness.

I would need a sketch to describe the console vertical leg.(it has a slight "S" curve to it trimming it back about 3" (find a picture to look at), and a 1/2" notch in the front edge to accomodate the seat back, but it is 12" high, cut from a width of 12" wood and 5/4 (1" thick) material. The console also has a vertical front seatback, 15 1/8" x 5 1/2" high x 1/2" thickness, and an aft vertical panel 14" wide x 4" high x 1/2"

The block that holds the console leg to the floor is 8" long, x 2" wide x 1" thick. See hull wood locating drawing on this site for where it screws into floor.

It will greatly help to look at some pictures, on this site or elsewhere, of a 13 Sport in visualizing these dimensions.

Later SS steering wheels are 25 degree dished, 16" diameter, 6 spoke and made by Grant. You could also use a cheaper 15 1/2", 5 spoke wheel by Schmitt, now being used on all Whalers.

Hope this helps you out! Have fun! It doesn't seem like a very difficult project to construct.

Before I varnish phillipine mahogany or teak (6 - 10 coats), I like to wipe on a mahogany stain for a darker, richer appearance. This also gives it more UV resistance from bleaching out the wood and turning yellow from sunlight. It will stay darker, longer. Buy varnish with the maximum (most expensive) UV filters in it. Some would disagree with this stain idea! BW just applied the varnish straight, no stain.

Thanks for the info. It's exactly what I needed. I won't need the console, I remade that about 7 years ago and it just needs a litle TLC.
I have the original white steering wheel, but I'm missing the silver dust cap that covers the nut that holds on the steering wheel, If anyone knows where I could get one of those???

Thanks again,

Larry, I made seats years ago for my 71` `13 Sport and the seats I believe were 1 inch finished(after planing). I measured the old ones before doing that and they fit perfect. You said to use 5/4, I am not sure what you meen by that? Maybee that is what you are saying to use slightly over 1 inch and then plane to 1 inch? Regards-Jack Graner.

Jack - in the lumber business, "five quarter" (5/4) wood means it is rough cut to 1 1/4", but is actually 1" when surface planed. Just like a 2 x 4 is actually 1 1/2" x 3 1/2".

The 1" nominal wood I mentioned is actually between 7/8" & 3/4" planed.
