Re: Boat Bondage!
I cinch her down tight in the direction of the surge (for and aft in my case) to prevent movement, we get a lot of tidal surge which stretches and cuts lines very quickly if left unchecked. I also use heavy chafe guards at all the turning points.
We survived the Japan tsunami surge using this method. In fact, it just occurred to me I haven't had to replace lines since before the tsunami.
