I have had them in all of my cats and where you are talking about. I have used to outdoor “RED 3-M” tape and it worked really well until some rough water and too much tackle hanging on it brought it down. Now I still put it on first , but now use two of the small “self tapers” that come with the system and I have had no problems. Just remember to stay on the support bar that you are showing. You only want to screw into the frist layer and it should be good, hense using of the short screws. I have had them in a Cougar FTD, 2 Pantera II, and maybe a new Eyra that is being bulit.
