Sprite
Yes, I will be using an M5 8mm o/d MaxiShaft for my recovery Sprite and I am more than happy to go with your suggested "Sprite Plus" measurements.
Slightly bigger will make it more usable more often in our Great British weather 🤣 and a 6mm keel sounds about right to me.
Thank you for making the drawings - I will start making the templates and cutting the plywood as soon as the drawings arrive.........please let me know the cost of the postage and printing etc as I really appreciate the time and effort that you are putting in.
.....and however long it takes you - it would take me 10 times longer.........and wouldn't be as good!
Bob.
