Boats and rocks:
When a boat hits a rock the rocks always wins if you’re lucky you have very little damage for the times you end up with a hole in your boat and need to repair the hole to get home? It hard to have everything you need to fix you’re boat so my list should be a good place to start.
Here are some items that can be use to seal a leak.
GE Silicone II
Toilet ring wax.
Tacky Tape (Camper Supply)
Gorilla Duct Tape
Because the hole is under presser when running you need to place a cover over it. Very thin Alum like pop cans or Alum roofing will work and can be cut with a scissors.
You may need some special tools like a:
Battery power drill and bits.
Pop rivet and tool
Self tapping screw or sheet metal screws.
