When I had my ODay 25, I had an 8ft Avon inflatable as dinghy - and a sort of lifeboat. The boat also had about a 30" draft, board up. The one time we had a taking on water emergency - returning from Dry Tortugas - I told the wife to head for and run it hard aground at a nearby Marquesas sand bank/cay while I bailed and tried to fix the problem. Turned out to be a hose had popped off a normally above the waterline thru hull. But the thru hull was below waterline while on port tack, which we had spent several hours on. Yes, ODay and I failed in not putting a seacock on the thru hull, but that's not the point.
Realistically, running hard aground is the among the easiest and best solutions for a sinking shoal draft boat - if there is shallow water nearby. Running aground means the boat is in a fixed position should a rescue be necessary, and the chances are very good none of the people on board will drown. If you are fortunate - like I was - you can fix the problem yourself before you even damage the boat.
2nd best option is the towed dinghy.
Last option is you enter the water voluntarily or involuntarily, hopefully with a PFD on, and a strobe and PLB attached.
Cruising with at least one other boat gives you another option for assistance which will slot in nicely with the above, depending on the nature of the emergency. I have really come to like small group cruises when I sail solo for that very reason.
