The thing is I don't want a mirror dinghy, I couldn't find what I wanted for sale. So I did a search, asked for a materials list, got some prices and did a rough quote.
I decided on a Northumbrian 10'6" designed by Selway Fisher. Very much an older style dinghy, with oars and a balanced lug sail. Which should cost around $750 to $1000. The labour I do for love.
Enjoy the journey. Looking forward to your build. You can always sail something else in the meanwhile but when you splash your Northumbrian it will be a special boat.
