Cranking up a downrigger weight puts a lot of stress on the downrigger's base. If you mount a downrigger on an H-Rail, cranking the downrigger will try to make the mount twist around the rail. You can eliminate that problem by adding a second attachment point on the hull of the kayak. For a description of the way I mounted a Cannon Lake-troll downrigger on the gunwale of my Revolution, using a block fitted into the water bottle holder to stabilize the mount, and an explanation of why I mounted the downrigger that way, see

Most fishing kayaks come with gear tracks mounted on their gunwales. Hobie could improve the competitiveness of its products by adding gear tracks to them. This is particularly the case with the Revolution, as it is a hassle to mount gear tracks on the narrow gunwales of a Revolution. And it would be great if Hobie sold downrigger bases designed for the gear tracks and H Rails on its kayaks, and included an additional attachment point off to the side of the gear tracks and H Rails to stabilize the downrigger mount.
