I wrestled with the exact same set of issues but knew it didn't make sense without first rebuilding the icebox (liner boat). Thanks to the Chesapeake gang's winter maintenances seminar I completed that this spring. Like you I was planning to keep a fair amount of ice in the box for drinks and cold(er) beer and in fact built part of the box with a divider for the ice that didn't allow water to flow to the dry side. I purchased an Isotherm holding plate system that uses a two speed compressor and a smart controller that detects shore power or alternator voltage (over 13.3 volts). At the higher voltage it draws about 5 amps and freezes the plate to around 7 degrees F. It doesn't pull from the batteries (alone) until the plate is in the low 20's and then only at 2 amps. It takes about an hour + with the engine running to deep freeze the plate back to 7 degrees. One other nice option to all the Isotherm systems is a replacement sink drain throughull that acts as a heat exchanger and eliminates any cooling fans or condenser fins on the compressor. This allows you to mount the tiny compressor in any small space without the need for ventilation. This makes the compressor more efficient in hot weather, keeps heat out of the cabin or locker and makes the already quiet compressor almost silent. That may not be as useful in Canada but made sense to me for summer in the lower Chesapeake.

I use a wooden/rope ladder that I made for myself. It is fashioned after the traditional pilot?s ladder with flat 4 X 12 inch rungs that are connected by a loop of thick 3 strand rope. There are 2 carbiners at the top which are hooked to the base of the shrouds. The ladder is long enough (5 rungs) that you can get your first foot on without much difficulty when in the water. The wood slats never contact the hull sides because of the rope around each rung.

A ladder mounted at the stern is much more useful if you ever have to recover a person from the water, and for recreational use, is much easier to use due to the backstay being there as a handy hand hold when you?re climbing in or out. (I recall your boat doesn?t have pulpits?)
