Re: water very close to getting into boat when boat waves come. Normal?
I reckon a canvas dodger around the back would give you more confidence. It's not very heavy, so doesn't compound the problem. It can be right across the back, with a slit cut in it for the tiller. You can extend it round the sides. And it can be easily lowered.<br /><br />It's not going to stop you sinking if the back gets stuck under for a long time (water will come through the tiller slit), but probably better than a solid one with a big hole for the engine.<br /><br />Trimming the boat level is probably more important though. I'm guessing it's tiller steared? Try a tiller extention so you can sit in the center of the boat rather than right at the back.
