I have a 93 Laser that i bought not to long ago and i have one port hole installed (not factory) right next to the mainsheet block. I happen to open up the porthole and i noticed i have 2 very large cube air bags in the bow (each side)and it looks like one under where you would sit. Is this something the factory has in all boats or is it something a previous owner put in. A bunch of guys liked how mine had it and were wondering if their boats came with them or where you could buy them.
