Here's a fishing kayak that comes in either dark gray, or three tone dark colors that's designed to be stealthy so presumably one can sneak up on the fish, undetected.
Earlier today, while at the Plymouth Walmart, I noticed five of these kayaks on display, inside the store, close to the fishing department.
Lifetime Yukon Angler 11'6" fishing kayak #91031, price $377
11 1/2' x 32", 78-lbs, dark gray or three tone dark gray-dark green- dull black
$377 seems like a very good price for a sit down/stand-up 78-lb stealthy fishing kayak like this one. Paddle NOT included.
