Not only are conventional cockpits highly overrated, but they are ergonomically disastrous for hobbits, who can't brace themselves when sailing to windward, see over the coachroof, while sitting down or sit with their feet up in harbour. Of course, conventional cockpits are designed as they are with the idea that people will be leaping about dragging ropes around winches and winding like madmen. Not a consideration for we(e) junkies.
David and I thrashed out a cockpit for SibLim that will suit me. It has a small, shallow footwell. It also has 2 levels of seating - one up high and to the side where I can sit in fine weather, using a tiller extension and enjoying the breeze and sparkling sea; the other is lower down where I can steer in less clement conditions, protected from flying spray and well braced against the cockpit side. If you are tacking up a river, you can't always use the wind vane!
One of the really nice features of Fantail was that the cabin back had a slope, which made a perfect backrest. On SibLim, this bulkhead is also the after end of the saloon, so the idea is not practical. I dare say I can use a cushion instead, but that will be something else to find a home for. Nothing's perfect.
