my solo paddling preference has always been sitting….with my knees against the gunnels. Not comfortable with either sharp or cold rails though. The wood is attractive too ...
A more comfortable (albeit less attractive) solution is to contact cement custom carved minicel knee bumpers to the inwale. Those can be whatever size, shape or width best captures and comforts your knees.
I usually futz around with various dowels to get the perfect height and angle intending to make proper drops when I'm satisfied, but somehow never get around to making them. So I have "prototype" drops in most of my solos.
You can always cut a wood seat drop, of any style, shorter, or angle in a bit more cant. Making shorter drops longer; not so easy.
I kinda know how deep I prefer my drops, even +/- on wildly different hull depths, and fashion them there and adjust (or usually not, that’s fine) as necessary. Getting the seat placement positione fore/aft is much trickier than depth.
BTW, I will now throw DougD under the bus. He has two sets of OEM Bell seat truss drops, Nice, skinny, dark (walnut?) Bell seat hangers, a short drop set and a long drop set, both canted a touch.
Those seat drops are from late Canoe Tripper JSaults’ outfitting adventures. JSaults sent them to me, I later sent them to Doug and he is ready to send them back to me. I still have no use, even for virgin OEM Bell wood truss seat drops.
It would be a lot easier if Doug mailed them directly to a good home. Given their JSaults pass-around history they really should end up in a Bell canoe someday. JSaults would be pleased.
