Not sure what you are talking about, but this a just 11,000 lbs boat. My last boat, which I owned for 30 years and voyaged some 150,000 miles, displaced 50,000 lbs without injury. I also caution against doing this with larger boats in the linked article. I assure I know how to handle line loads and have written extensively on just that: www.morganscloud.com/category/docking-tying-up/online-book-docking/
