Welcome Edward,
Great to have you join us - and finally to post your introduction.
I've got 60 years on you but also have fond memories of the 420 dinghy. If you do a search on my
GregAfloat site you'll find mention of them. Back in 1966 I learnt to sail in Chichester Harbour and the Council's Adventure Centre there used them and Enterprises. I far preferred 420s. They came up dry when you capsized them!
Unfortunately, I sold my SeaHawk in 2018 after owning her for 14 years, but I had great times aboard her. (My Dad had one too, but he sold it in about 1980.)
C-Auk is, I think, the only Pyecraft built SeaHawk I recall going aboard. You should find one or two photos of your boat somewhere on the site.
I've upgraded you to "Member". That should mean you can post virtually everywhere on the site now.
