Thank you everyone for the info. This is my 6th boat since covid started. I started off with a simple beach boat, then a junk, a dhow, and Slocum's Spray, all scratch including the latest two, Inglemanland and the Mordaunt , the only thing I bought was chain, paint, basswood sheet for the second planking and thread to make my own rope. I learnt a lot each time and tried not to make the same mistakes. I've nearly finished this one so maybe I'll get the next historically correct as well, even if the design isn't an exact match because I don't use proper plans.
Thanks again
Mick (Dr. Syn)
