Greeting all!

I would like to ask a question. I looking to purchase my first Kayak.
I have done some mild Kayaking in the past and have developed a good
idea of what I am looking for (basically a shorter touring/rec kayak
with at least one dry hatch). Anyway I am looking specifically at the
Wilderness Systems Cape Lookout 135 and 145.

I really like the fit of the 135. I have sat in both several times and
paddled the 135. I like the 145 as well, but don't like the fit quite
as much. I'd prefer the 135. I weigh 215 pounds and the 135 has a 240
weight limit - on occasion I would be interested doing some overnight
trips and I'm concerned about going over this weight limit with the
stuff I pack. My question is this (don't laugh): If I go slightly over
the limit - like 245 or 250 pounds (due to gear and food) am I going
to sink? I would guess not - but I though I'd ask some more
experienced paddlers.

Thanks for any advice or experiences!
