The latest incident was a 300 m long boat and compared to smaller yachts, she is not riding up on each wave why a hit is harder. Octopus is half the length and should probably got away better.
Which brings up the question: what would the optimum length be for surviving extreme waves. (Assuming something less than a battleship.) Or rather than length should the concern be the length to freeboard ratio?
Just to stir the pot, there was a post on another site about how 100' MYs can snap like sticks. That post was by a trawler fan, who made no bones about not being a fan of stylish yachts. On the other hand I have also read that yacht type trawlers are something of a deception, as they are much lighter than a commercial trawler with its hold full of fish. Not trying to take sides on any of these statements, just showing the range of confusion out there when it comes to sea keeping.
