Prowler 15

I just bought a prowler 15 $400.00 With seat from a rental yard, in Moss landing California. I noticed it seems a little more tippy than my Swing. The beam on swing is wider and length is 2 ft shorter. In fact i Flopped it on the way out in surf where the swing I don't think I would have. My question is about the front hatch. It seems loose and not water tight are they suppose to be water tight, I like the larger hatch, and do guys put poles in there during launch if so how the heck do you get them out. Last but not least are there some pictures on the best way to set it up.
