You actually can mount that one to the pylon as well by flipping the boom over so the mount end will be up higher, and the curve will sit on the gunnel of the boat. There was a misunderstanding in the ordering of the pylon for my 18' (they thought I said I had a hydrodyne inboard) and I got the curved inboard boom not knowing it was not the correct one. Figured out that it mounted fine basically upside down. But that one is now at the bottom of the Mississippi, and I have the "correct" one for the 18'. Both work fine though.
River rat, do you have any pictures of his you mounted to boom? I'd be interested to see what that looked like . My only concern is being towards to back or the boat and potentially barefooting in boat wash .
I do not believe I ever got pictures of the first one with the curve. I only had it a couple weeks before it went swimming. It is essentially the same as the one with the T-bar, except the curve sits on the gunnel instead of the T-bar. The spray from the boat is not an issue at normal shortline distances when you use appropriate trim. With no trim, the spray comes out from just in front of the dash and goes wide. This will spray your feet. When you trim up a little bit, the spray moves back significantly and does not launch out as far. You can also angle the boom forward a little bit if it really concerns you.
You have most likely figured out your issue of how to install a barefoot boom. Anyway here are several photos of the boom from KW that I bought with my 20. It works real well with the bend in the attachment bar.

Last summer was my first with my hydrodyne and I put money into recovering the seats and installing new carpet. We enjoyed the boat quite a lot, but never liked the dull grey paint. Just last week, I brought the boat back from the lake to repaint the top side with an interlux Blu glow white. I still have the finish coat to do, but so far, so good! For the final coat I'll be painting at my friend's warehouse. It's amazing how much better the boat looks with a fresh white coat of paint. I also plan on ordering Eva foam traction pads instead of the teak strips that were originally on the boat.
