Toonoc, I'd shy away from the waders if I was in open water, but for kayaking in flat water, I'd wear them... You dont want to go swiming in waders. The secret to winter kayaking are kayaking mittens called pogies. They're waterproof, and pretty warm. I dont use them because I'm always fishing, so I just use wetsuit gloves. You can also make a winter paddle that has foam pipe insulation handles to insulate yoru hands. The key is to bundle up with many layers and to keep dry.. thats basically it... Going with a buddy is very important, as well as having a PFD of some kind with you.
My rig is a 18ft chesapeke lightcraft that I built myself. Its the most stable kayak out there and feel very confident winter fishing even in wavy conditions.. The only problem is that i have a leak somewhere and I cant find it
My secret plans for the july slump is to mount a fishfinder on it
Oh and fix the leak..
Your kayak sounds awesome for winterfishing, with all that storage
