Hi, Julian.
No worries about the cabin access (or the view forward) on the CBL. Just step over - or down from - the bridge deck and you re in. Good sitting head room and - with the closed cell foam (Old, cut to fit Kip Mats) very cosy even before using the self inflating mattresses.
How are you fixed for getting over the cabin top in a hurry? When mooring bows on, single handed, I have to get up front quickly with shore lines or a boat hook. Shuffling down the side decks and leaning over the cabin to stop excess heeling takes too long on the CBL. Wriggling up through the fore hatch takes FAR to long! I have a removable step on the bridge deck to leap on to the cabin top, grab for the haliards on my way to the mast. Hope you have a better system. A sliding hatch would be a distinct liability for me!
Agreed. Washboards are a pain! Can't use your idea for fold back upper half and fold down lower as I have hatches for light and air either side and dont want to restrict access to the bridgedeck lockers. My idea is a one piece, slam-in job with a central, restricted hinge to replace my 4 wash boards - when I get around to it!
I'll send you a pic if some one will remind me how to do it!
