Electrical tape simply does not work in a marine environment. Even duct tape won’t stick to something wet. Try getting any tape to stick to a rope or line on a boat. Or try to get a waterproof seal on a hose leak. X-treme tape can do all these chores with flying colors because it is a non-adhesive, self-bonding wrap. It’s not really tape since it’s not sticky. This stuff is sort of magical. You stretch it on and it self-fuses tight under tension. It works in cold and wet, and won’t melt on hot surfaces, so you can use it on engines. It is easy to apply even when it is below freezing. The tape doesn’t stick on itself until you want it to. Once tightened this silicone based wrap forms a reliable bond even in water. I use it as an insulator around wires, like electrical tape. I wrap the end of ropes with it. X-treme tape bears up for many seasons under constant UV and sunlight and the extreme cold, heat, and wet of harsh weather. It’s so good I use for any outdoor tape application.
