Thanks guys, the survey is, of course, a must....was just checking if it was ludicrous to get that far in knowing the hull was 5mm, and not twigging if it was too thin... feel more confident in the boat now, still curious about the windows - they look like the sort of thing you find on a house not a boat, any ideas?
Grahoom....budget is about £20 000 at most, this NB seems to be negotiable... I have prioritised looking for a boat with sound shell and decent engine/mechanics and electrics, over looking fabulous on the inside. I can always tart her up at leisure as I go along but she has to float and she has to move and I have to be able to function on the inside (lights, tea making facilities etc!) think I ought to be able to get something reasonable - if a bit basic - for that money (let me know if I'm sounding ridiculous please ) funds will not extend much further than the purchase after budgeting for license, maintenence, insurance, fuel etc) until more can be earned if you see what I mean...
