SIK re-entry is not that hard, but
I still would go with a SOT for fishing. I have a rec SIK and it has flotation in both ends. I did practice at the pool and figured out what works well for me. I can re-enter almost as fast as I can with an SOT, possibly faster in a full capsize because the SOT is harder to flip back over. But, I have to keep the front deck clear or make sure it is very easy to clear. You should practice getting back on an SOT also; it isn’t as simple as it may appear. Anyway, the safety issue is often overblown. When properly rigged, there is not much difference. The SOT is a little better, but the SIK is no death trap or anything.
