Re: Could You Survive a Collision

Things like this will seriously curtail night sailing. We try to keep a good watch but this could ruin your whole day.

Re: Could You Survive a Collision

I believe I and my boat would survive the collision, although probably with some serious damage. My boat is small and the speed of impact would likely be less than 6 knots. It's an Etap, with two hulls, and foam filling between. A large volume of foam is in the bow under the vee berth, so a lot of the collision energy would get absorbed there. If the outer and inner hull are both penetrated we still won't sink, there's 100% foam flotation. Please don't start telling me how the foam absorbs water! The rudder with a large hole from ice and immersed on a mooring for 25 years had dry foam when I dug it all out.

Usually don't try to hit the dock, normally come up to it easily and then tie up.

Re: Could You Survive a Collision

Absolutely! My 31 ft steel origami hull is 3/16th plate. I have already T-boned a concrete dock, and one of my 36 footers , of the same thickness, sailing at hull speed, has already T boned a steel barge, which was tied to the dock, with zero damage . Another hit a submerged barge , on a sharp corner, doing hull speed. He caught the corner of the barge , just off the centreline, at the bow. Zero damage, except some scraped hull paint.
