thanks everyone -
she has a BUKH DV20 - so will happily potter along.
I've heard nothing but good things about these and the previous owner is just down the pontoon from me with his new boat - he's already been extremely helpful and offered to help out/advise on pugwash and take me out on his new boat! he left all his marks in the fish finder/plotter so will start with those!
to start with im thinking mackerel bashing, plaice, whiting, bream, rays, etc in the bay, try the ledges at ringstead, and lulworth, portland harbour/breakwater working up to the adamant shoal, and see how i go - the shambles wont be tackled until i'm more competent - with strong tides and a displacement speeds i want to be confident before hitting that!
its not just a fishing boat either - I plan to do a few day trips with friends and family to lulworth cove, round the cruise ships, etc swimming and snorkeling, that kind of thing!
