On first glance, I think that I would want a recessed trolling motor foot petal. But then again, I don't think so. Same for the 'attached foot petal' item.
I run the trolling motor from several different positions, depending upon circumstances. If sitting (especially when I use the c-rig), I need the petal in a particular spot, which is not the front center of the deck.
When standing, i will move it around to fit the circumstance. On my boat, I virtually never have the petal in the front center. Having it there would be ackward for me.
Actually, I have considered switching to a hand operated control for several reasons. One being, I'm not the most nimble on the front deck. Two, I believe that I will actually have more control with a hand guide. Several serious fishermen in our club have hand controlled trolling motors, rather than a foot control.
