The one time I was out on the sea we had waves breaking over the bow and hitting the bridge (a little less than 100 ' back)<br />This sea going ship would crash like a dead bird when the bow ran out over nothing*. ie when the wave passed the center of gravity and hoisted the stern. <br /> I see a slight chance this design pitch poles, or does a pretty neat variant. <br /> Remember its not to far off the English coast that oil rigs encountered "impossibly high waves". <br /> *you should have heard the captain having been awaken when he got to the bridge. Lets just say none of those junior officers ever did that again.brucehttps://www.blogger.com/profile/06911036379896402069noreply@blogger.comtag:blogger.com,1999:blog-6244999628674918029.post-56768924027107928752014-10-30T05:08:49.919-05:002014-10-30T05:08:49.919-05:00@Paul: I'm not sure that this hull will be as...@Paul: I'm not sure that this hull will be as unseaworthy as you expect. In the first place, it's a patrol craft, not a seagoing vessel - it's designed for operations in shallow waters, where it can take shelter from storms behind islands or in harbors. It won't be hundreds of miles out on the Pacific Ocean, far from land.<br /><br />As for seaworthiness, the catamaran and trimaran designs are becoming more and more prevalent in the Pacific. Australia developed the basic design a couple of decades ago, and many other nations have adapted it - see, for example, China's Type 022 missile craft, which are catamarans rather than trimarans, but their hulls follow the same basic design concept. There are over 80 of them in service, which suggests they don't have too many problems with the weather they encounter - otherwise they wouldn't have been built in such numbers.<br /><br />I agree that in an Atlantic storm, things would be different; but the Pacific's not the Atlantic in terms of 'normal' weather.Peterhttps://www.blogger.com/profile/10595089829300831372noreply@blogger.comtag:blogger.com,1999:blog-6244999628674918029.post-59992026686537865842014-10-30T00:16:57.453-05:002014-10-30T00:16:57.453-05:00245 tons? Anything over a modest swell, and that b...245 tons? Anything over a modest swell, and that boat's going to be a charnel house inside if there's a fight to be had. At 4,000 tons, I get bounced around like the mixing ball in a paint can in anything over force 7 seas. <br /><br /> Semi-serious joking aside, It'd be a real challenge to work a non-traditional hull like that in a modest gale. The not-meant-for-open-water (trihull) variant of the LCS is reputed to be crank and prone to wild griping in a confused sea, and that's with all the added beef of a lot more mass. <br /><br /> Really, to me, with an asymmetric profile immediately above the waterline, these trihull designs are going to yaw and roll wildly when they're not head to the sea, and there's enough moment to push them bow down so that the wave-piercing bow is only stabilized on one side by a sponson hull. <br /><br /> It's like the America's Cup boats today. They're amazingly fast, sink on a whim and in a sea, can't compete with wooden sailboats built a hundred years ago. As interesting looking as these gator navy boats are, it's hard to see them as useful beyond swimming distance to shore.Paul, Dammit!https://www.blogger.com/profile/02264872375942355609noreply@blogger.com
