More trimming of the pattern.
The curve at the front I traced from the nose of the board.
I wanted to maintain width opposite the mast track, but needed to end it sooner.
Marked a couple of curves, did two reductions using a piece of punch strip as a batten.
Too involved in what I was doing, no photos.
Happy with the shape, traced the red to white colour change on to the pattern.
At this point assembled a big trestle table to work on.
Got a white deck pad out of stock, rather grimy from storage.
Marked the first bit of pad and cut.
Roughed out the handle, mast box, and vent.

Trial fit...

Doing white pad on the white, red pad on the red.
The white will get filthy, but I'll deal with that when it happens.
Using a matt cutter to cut the pad, vertical on one side, 45 degrees on the other.
It runs along a straight edge for the straight bits, freehanding the curves with the 45 degree cutter.

Main thing is to tape the patterns down, minimise movement.
Pad bits I have not long enough for a full board, second bit for the tail.

The straight cuts I marked on half a diamond on one side, the other side where it fell.
Red sides again straight on half a diamond.
Cut the straight bit that has to match the white first, then free handed the sides.

Trial fit....

All of this is only possible with a big table to work on, that you can cut through when cutting the pad...

Time to stick down.
This used to fill me with fear.
Slit the backing of the main pad down the middle....

Duct tape one side in position firmly, so the other side cannot move.

Peel back the untaped side, sticking progressively.
Hard to get the backing off at the vent, mast box, and handle.
Actually quite easy to line up, as the pad will distort.
But it's one try only - once down it is stuck.
Second side retrieve any scraps of backing left in the centre.
Not too bad...

Added the white tail piece the same way, red sides more freehand....

Got the look I wanted.
Up close, the curve at the front looks a bit like my dog chewed it for me.
Tail looks OK.

The cut out for the handle looks a bit like I chewed it myself.
Mast box and vent a bit off centre.
But the look I wanted.

Pushing to be ready for a paddle tomorrow, threaded a shock cord through the tie down points up front.
Flipped over, examined fins.
I'm sure it would be fine with the stock fins, but I have had some special ones delivered.
Main fin supplied was an 8" "Orca"
Nothing wrong with it, apart from I want a colour contrast centre fin....
I have Greenough 4A and 4C, both straighter.
Decided it was probably overfinned, went for a 7" 4C rather than a 9" 4A

Sides I am mystified by the Sunova sizings.
I have 3.25" and 3.7", the Sunovas are 85 or something.

Went for the 3.7" True Ames.
All fin choices based more on pleasing contrast colours than science....

Tomorrow a paddle....

Maybe................................
Sorry Tardy, meant to answer.
When I feel the lack of a tail pad is limiting me, I will add one.
So probably not soon.....
