Great boats, and although not especially fast/close winded by modern standards, they are quicker than most 'cruising caravans' and have plenty of space inside for weekends and more away.
As for drying moorings, our seal 22 (No. 249) 'Moonspinner' is on a drying mooring and last year was in a spot where it was 'a bit hard' comprising a little bit of mud over shingle/broken shell etc. In that position she heeled about to about 15 degrees when dryied out but it didnt cause any real problems, just a few tide-stains above the waterline and of course we had to remember to stow things well inside.
I took the view that heeling a little was perhaps better than leaving her with beaching legs which could easily get bumped, and/or dig in and then be subjected to shear loads she re-floated. I gather the same level of heeling may occurr with the Baker built 28's
Also, perhaps of interest, I carefully checked the 'keel-land' under the hull, where cast iron bears on GRP when the boat 'sits' on the keel, at the end of last season and found no more than scuffed paint/antifouling in this critical area - a good result after a year of bouncing around in the grunge...
I plan to simply rub-down this area and paint on a coat of thickenned epoxy 'every year or three' to prevent any possibility of the keel wearing the GRP 'bearing area'. Im probably being over fussy, but as this is recorded as happening once to a Seal 22 a few years ago, resulting in a scuppering, doing it will give me complete peace of mind so will be part of my maintenance schedule.
However the heavy build quality and lay-up of these boats, is such that wear in this area shouldnt be a major worry! You are far more likely to find stress/fatigue/flexing/crazing problems on one of the more lightly built modern speedsters than these tough 70's built boats....
This year, at our request, we have been alocated a different mooring a couple of hundred metres away with more depth of mud in which she dries out high and more or less upright (perhaps still on shell/shingle), and although I have about 250mm 'less water' relative to our old mooring, i think i'll still get about three hours sailing 'on the tide', which I think is worth the trade off for drying out level.
lastly, I see you now have a pic' of a lowered keel, but if you want photos of the keel (out of the boat), of the inside of the keel-box, or of the component parts of the lifting mechanism (although not that close up), let me know and i'll email them to you....
