Hey Guys, don't know where my last post disappeared to but here goes again.
Red large scupper plugs work great to plug rod holders. They keep water out of unused holders if you flip. Also, they keep bugs and other critters out when stored. They can be had here:http://kayakfishinggear.com/oceankayaks ... pairs.aspx
As far as better seal on hatches, I used 3/8" closed cell foam on the lids, seals well and keeps it more efficient if used as an ice chest, then replaced the stock 3/4" trim-seal with 1 1/2" trim-seal.
That can be found here:http://mooreindhardware.thomasnet.com/i ... c?&seo=110
You have to call them to order (800 543-1677) they don't have online purchasing available yet. At least they didn't when I bought mine. The item # is 7100-1/16-C.
Don't let the item in the drawing confuse you. The letter at the end of the item # denotes where the bulb goes. "C" means on the top, not on the side as in the drawing. You'll need 10 feet. It works great and keeps everything dry...as long as hatch is closed...duh! I turned mine turtle on purpose and sat on top of the hull for 15 mins. to test. When I turned it back upright, it was as dry as a bone!
