Hello Folks
It is seven years since I made my moulds and I have been using them to make canoes with no need to draw up fresh plans.
Recently I made some strips for a customer to make his own boat and he is in the process of drawing up his moulds.He came to see me for some more strips on Friday and asked if I could explain how to plot the stem moulds.

He is making a 15ft Bob's Special from the latest edition of Canoecraft.
we worked out the plotting of the points as shown on the link for revisions and I have sent him the revisions page so we now know the figures are right but....

It still leaves a large gap of unplotted curve from the last point plotted on the 18" line to where it joins the number 6 station.
Are we correct to assume that this is just to be drawn freehand?

Its a long time since I made my moulds
Cheers
Alick

Hi Alick,

I did up my molds for the Freedom 17 from the table of offsets, which I think is what you are asking. I put up a detailed account here:

Maybe there will be your answer in the post.
