I'm using the Inno Rack with Locks (https://www.cargogear.com/OneItemInfo.aspx?partnum=INHFIT15) and paid $299 shipped purchased May 2020.
I've updated the album to include pictures of the bow and stern attachment point. I have one on the driver side and one on the passenger side. I can't remember where I purchased them from but they've served me well.
I have the Malone Foldable J-Rack (https://www.amazon.com/gp/product/B083KN8GYF/ref=ppx\_yo\_dt\_b\_search\_asin\_title?ie=UTF8&psc=1). However, I do not recommend them. Within a month the locking mechanism became very loose and hence the bar has a little play. It still works but I don't think the longevity is there.
