And .... We have a winner!

A BIG 'THANK YOU!' to N. Vass who has provided an image of the company's brochure!

She's a Havencraft 16 built around 1967 in Newhaven!

Excellent news Morgan! And thanks to Nick Vass for 'finding' her.
Googling her now, I see that the owner of the catalogue shown above has offered it for sale on Ebay for US$ 9 (or $8.99 to be precise).
