Still dreamin but only just

Good news I can paddle a Kayak (and I love it). On Saturday had a paddle of a friends Viking Tempo and his Viking Nemo, the objective was to make sure I could actually get on board and paddle successfully. On Saturday evening I was fitting out a new Yak in my dreams. Today at my friends suggestion we took the Nemo to a local outdoor pool so that I could try reentry from deep water to cut a long story short I could not do it basically, because of my disability, remember I have MS and cant use my right leg. When I could get my body on the Yak I was not able to right myself without tipping back in to the water, I think I managed it once in about 20 attempts. I dont want to give up but I am wary of the possibility of being tipped out by some unthinking stinkboaters wake even if I pick the right conditions. Can anybody think of something that might help :?:
Are outriggers a possibility on SOT Yaks :?:
Are there any aids to reentry that I could try out :?:
