Naval News Reports that, “Italian shipbuilder Intermarine launched the longest self-righting and unsinkable boat ever built in Italy.” At 33.6 meters (110′), length overall, this may be the largest self-righting rescue craft in the world.
Our own 52′ Motor lifeboats are becoming unsupportable, as made clear by the recent withdrawal of Victory, now 64 years old, from service. Our 87′ patrol boat are approaching the end of their service life. It may be time to look at what others have done and procure a larger, more powerful, and extremely seaworthy self righting boat capable of replacing both the 87 footer and the 52 foot MLB, at least in ports where a maritime terrorist threat is extremely unlikely.

31 knots would be remarkably fast for a vessel of this size with the power indicated, faster than either the 87 footers or the 110s with less power than either.
