I'm not familiar with these but I would just caution any inflatable that would be used for fishing.
Hooks/fish etc can all to easily cause a puncture.
For floating/paddling around I say why not! Just be sure you wear a PFD( life vest)in case you deflate
and be extremely carefull about water temps.
Most drownings/hypothermia in spring occur on warm days...............but the H2O is extremely cold.
ask more questions! Thats what this site is for.
* I just checked the FishCat out.Looks to be made for fishing...............but the price is $$ a bit expensive.
I would really try to stear you toward a sit on top kayak.............
Inflatables are notorious for being bought and seldom used due to the hassle of inflating/deflating them.
Hope this helps somewhat!
I'm sure other will chime in on this subject
