i have looked at many boats that have been hit some with little to no apparent damage others with massive damage but every one of these boats had 2 things in common 1. the hull/s were holed as the hit went to ground(some were as little as pinholes some above water
line some below some fist sized holes)
were fried only simple motors escaped (no computer parts)
So if your boat has been hit get it out of the water
pronto to find the extent of damage,it will have holes just that you may need a keen eye to find them, cats normally only have one hull
holed but electronics
fried all over the boat.
i base this on around 11 boats both cat and mono,glass,composite and wood.
Haven't seen a steely or ally that has been hit yet
