My solution for this is as follows:
1. go to
http://www.watertrailgear.com and look in the coolers and bags section. The right one for the forward compartment is triangular at 36L by widest end 19 wide. Fits perfect in the bow compartment of my revo.
2. go to wallyworld to the cooler section by sporting goods and get the roll of flexible steri water bubbles for freezing and because its 2in round seperated water bubbles trim it to size, (plus in a pinch you can pop them and drink).
3. The cooler bag has a thin insulate reflective lining. This is no good for fish which will easily cut or puncture it. Solution is to call a pool installer that has remnants of heavy vinyl pool liner which they will give you for free. Get 3m 5200 and cut the vinyl to size and attach sides with the 3m to form a sleeve to insert in the cooler bag. Leave enough room at the top to roll down and clamp. When done for the day pull the sleeve of fish and rinse. No smell residue in your cooler bag.
