There are a few other threads on this you can find, but here's my $0.02:
Kayaks are OK for getting you and the bare essentials to a shallow and secluded spot. I would caution against hunting "out of" it. I ran one last year and it was fun, but now I have a dog and will use a canoe this season. I'm looking forward to carrying more gear and a hunting partner as well. I'm on the lookout for a tiny used 2-stroke and then I'll really be able to go farther with more stuff than last year.
