Your rubrail and perhaps the spreader-bar/setup they use will push the straps away from your hullsides as they 'rise'. But you really want those beach/terry towels in between any portion of the strap that touches the sides of the boat, as the boat/strap will shift/slide a little bit as they bring up tension to lift away from the trailer.

Installing electric brakes this week on my trailer. Fresh water. It looks so much easier. I here they are installing them on a lot of new trailers

Nothing wrong with staying home during the rain. Hmm while Subject of submersible is up.😄😄😀😀

So far had my electric brakes in n out of the water at least 20 times. Unplugged each time, did not seal wire connections figuring water Will just st trapped anyway so far so good

Ordered the trailer for the Fountain with elect brakes used it for seven years no problems worked great, amazing really. Removed the scary surge disc on two axles from under my "new" Scarab welded the coupler and switched it to elect drum on all three axles. A direct bolt on. Back to being confident towing. But I only see fresh water. And I do unplug before dunking but it is as much for the trailer lights as anything

Stainless lines and stainless wheel cylinders and use water for brake fluid...

Nice looking scarab 😎
