Welcome Aboard!
I would pull a site search on the word "Doel Fin" and read the past comments on such. The site search tool is at the bottom of the home (kind of hard to find, maybe I can get that fixed ) I though am not a big fan of the Stingray due to the large surface area (and drag) of that product and that fact that it is plastic and can flex and is (unlike the hull) the wrong place for having that feature. As far as your normal service goes, it is not that hard and in many ways easier than working on your truck
