For the restoration of this boat I've found a benchmark to aim for. I want this boat to be a cruiser and not a racer.

Good, Gary.
When you eventually start the sail-making project, I hope you take lots of photos, and finally produce a photo-article about it. 

Cheers, Arne

Could that cabin renewal be postponed for the winter? The cabin is not needed to make the rig work (but the foredeck must be ok). I am asking because time is running, and if sailing has some priority, it is best not to rip the boat apart now. There will be enough to do anyway.

PS: It should be piece of cake to add a wooden top section to that 6m mast tube, but it takes a bit time. Everything takes time. Tic-tac tic-tac...

Good, Gary, then you are spoilt for choice.
Now, I find that making the sail is the easy bit. The big job is the rigging  of the mast and sail. I suggest you prepare for a new mast, yard and battens, while you are waiting for the boat to arrive. With mast and sail in hand, you are almost there.

Good luck!

Hi Gary.
The sailplan for the Hartley TS-16, which I made in 2016, was a little un-finished, so now I rewrote it  and redrew the diagram in QCAD, and then added four individual sheets of diagrams. Sheet 2 and 3 have the essential numbers to loft the panels (if using the barrel panel method), and sheet 4 shows the positions and lengths of the batten pockets.

Hopefully, these sheets will lower the threshold for bringing out the sewing machine.. Just follow Chapter 5 in TCPJR.

Good luck!
Arne
