I actually had a few wires that ended up rotting out, likely due to sitting in the water for years. Went through a pretty extensive project to install a rigging tube in place of the tray on my 17'0 We ended up foaming the entire rigging tube in and fiberglassing to matching the rest of the deck and closing in at the transom. I assume you are looking for something a little more quick/easy, but really happy with how it turned out. More protection for all the houses and wires, no more standing water and all drains out, more structure with the added foam, and a really clean looking deck.
