Hi Ian,
I'm only aware of 2 (amateur) BR17 kit builders at the moment, myself and Steve Jones, who has also posted on here. I've been working weekends and evenings since Boxing Day 2010, with other projects, holidays and business trips getting in the way. I have very nearly completed stage 1 in the instructions, which is the hull and structure up to the level of the floor. But I spent a lot of time at the start on pre-coating the panels, which I hope will allow me to accelerate the later stages of the build. Certainly once I get the floor in, it looks pretty straightforward and fast to do the top planks and the remaining structure.
From his pictures, I think Steve is much further on, but I think he has had much more time to work on the boat.
Mine is a full kit.
Regards,
Anthony
