Just wondering if any one out there has an interesting solution for a rear knee brace, I don't like the arch gunnel to gunnel brace, I'm looking for a different solution something in the middle and sturdy enough to lean against. I'll look forward to the creative solutions that will come.
It's a great and interesting design problem and I'm glad you brought it up. I'm also interested in what genius ideas the WBP have come up with...
Here's my take from tackling the problem earlier: In trying to figure out how to do it in wood, every design I came up with would have to in some way be integrated into the rails or the floor (kinda like the others shown here). It seemed to either be bulky (bad b/c I like a lot of floor space for coolers, tackle, and kiddies) or it would not be sturdy enough. There's a lot of force being exerted at the anchoring point(s) on these things so you need either multiple points of attachment (i.e., rail-to-rail) or a robust base (i.e., the pedestal approach). It's just hard to make slender - cantilevered forms out of wood.
I built it from scratch without any plans. I just drew some circles on the floor of my garage untill I got it right, although I would change the offset a bit and not make the bottom curve offset from the top curve as much; that would give more room between the rear seat and the the kneebrace.
This is a modified version of the Kingfisher design Jason has and I used his plans to build it, although It is modified quite a bit from his plans.
OH, I forgot to mention - the front AND rear kneebraces are removeable.
Makes it easier for transport and when there isn't a second fisherman in the rear, there is more room for storage on those longer trips (one more cooler for beer - hehehe)
Dan, are you running a rear floorboard? How about something on a removable floorboard system? Do you like the concept in the Hyde boat above? What is the distance from the rear of the rowers seat to the front of the rear passenger seat?
