Hi, I'm looking for some advice please. I own a 6m Humber Destroyer which is mostly used for diving. I would like to have a modular set up where I can either fit a cylinder rack or seats depending on my needs. I'm not that keen to have my young nephews sitting on the tubes when I take them out for a trip on the Solent so they haven't been out yet. Does anyone know of a good boat fitter who could help me out (Southampton/ Portsmouth area)? Many thanks. Mick.
