Cruisers in the Pacific Northwest
, including the inside passage
, regularly hit submerged and partially submerged logs
. In my first season in Puget Sound
I spoke with three boat
owners who went up to Alaska
and back. All three hit something. Two hit logs
, and one hit a rock.
The two who hit logs got holed. Those were fiberglass
boats. Both had to interrupt their trip to repair
their hulls. One boat lost
its entire summer season to the fix, and the other took several weeks for the fix.
The boat that hit a rock was steel
and took a dent.
If you have a cored hull
hull and hole it, I would imagine that the skill level needed to fix it properly would have be be more sophisticated. You might not find that level of skill depending on where you hole your boat. Something to think about. If you are just sailing local waters, no big deal. If not, then maybe, yes, a big deal.
Having run over in broad daylight a submerged log that was about three feet in diameter, I can attest that **** can happen especially if you sail where big trees grow. In my example, I am pretty darn sure that the log monster would have badly bent my prop shaft had I not had a prop encased in the skeg. In fact, think it could have snapped a spade rudder
or bent that shaft. I never saw it until after we hit it (two very big thumps, one for the keel/hull and the other for the skeg) and it popped up many yards behind us, surfacing in slow motion like a whale.
I think cored hulls are fine, in some waters for some purposes. They do a lot of things well. I question their impact resistance and the difficulty of repairs
. Certainly, it you hit something you need to pull the boat out or dive for inspection
even if you are not leaking water
into the interior
because you need to find out if you are leaking water
into the core
. The outerskin typically is not very thick because the whole point of cored hulls is to save weight.
