Just my .02 on the ladder.
I bought a wooden replacement handle for one of those big, 160 Qt. Marine Igloo coolers. The kind that attached to the cooler with a piece of nylon rope. It has holes pre-drilled on either end that you can run a rope through. Then I looped it at the top. Then I looped the loop threw another loop at the end of a long piece of rope, hook it to the cleet on the side of the boat and hang it off the back where it would be, when extended about 4' into the water. The handle is stout enough to hold me and I tips the scales at around 235. I've got the handle on the back of the boat to pull on and generally speaking, I can get in without too much groaning. I'm going to get another handle next time I'm near an Acadamy, and attach it to the rope about half or a third of the way up the deck so I can grab it and come on board. I should have thought about that the first time, but as with many things in my life, I've got to screw up the first time to get it right the second time. Anyway, it works for us, and it isn't bulky. Plus you can use it to tie off to the redneck yacht club if need-be.
