I saw that on the news last night. It looked sort of out of place in this day and time, seeing those shipwrecked sails leaning over toward the water.
It does seem odd... doesn't it... but that same thing happened hundreds of times especially off the coast of WA/OR... its an unforgiving place.
It was bad enough to see it awash in the surf on what appeared to be a sandy bottom, but it was heartbreaking to see it smacking into the rocks of that jetty. That's gonna leave a mark, and worse. There's no way to hit rocks like that and not do just horrendous damage to the sheathing. Just makes you sick to see it.
