Legs/paddles Brown biots or knotted rubber (1 pair)
How to tie it
Tie in the back strip and rib at the bend, then lay a strip of thin foam along the top of the shank; the foam is what floats the fly (a Boatman that swims down but bobs back up).
Dub a plump yellow/olive body over the shank to form the boatman's rounded belly.
Pull the foam and then the brown back strip over the top and secure behind the eye, giving a domed shellback.
Counter-wrap the rib forward in 4-5 turns to segment the back and lock the shellback, then tie off.
Tie in a pair of biot or rubber 'paddle' legs angled back like oars, whip finish and cement.
