21’ flats boat over 6,000 miles across the Atlantic
These guys got some cajones. And well-beaten kidneys. Interesting view of boat design regarding capsize prevention. I posted a bit back about an idle - and maybe impractical - idea I had for inflatable gunnel bags. Looks like buoyant gunnels are built into this boat. Here's an excerpt for those who are not allowed on the site - it requires free signup. You can google most of it up using this subject, but maybe not this new article from Boatest. Some interesting videos, including one taken from a UK S&R chopper of the boat in 12' seas. http://www.boattest.com/Resources/vi...px?NewsID=3836 "As soon as you flood the bilge of a boat it starts to become unstable, Brown said. When the cockpit is flooded the boat can easily capsize which is why we put two 3-1/2 scuppers in the transom of the boat. Brown went on to say that he used rubber exhaust pipe flappers to cover his scuppers on the outside and act as a check valve. Once the cockpit of a small boat is flooded, the free surface effect of the water as it moves from side to side unfettered by baffles will usually capsize the boat. I filled the hull with foam flotation and placed it on the outside in the gunwales to make the boat harder to flip, Brown said. I knew the boat would never sink no matter what happened." Also of note: "In fact, the transatlantic boat seems to have been impervious to the free surface effect simply because there was very little room for water in the cockpit. The foredeck of the Intruder C-21 is a flat casting platform with six hatches for storage. The cockpit was filled with numerous large containers of fuel, water and supplies, leaving little space for anything else -- including sea water!" So there's one solution to avoid shipping seas - fill your boat with "stuff!" Better have it lashed down well though. --Vic |

Don't ask Harry anything, he is a frekin' liar and not worth wasting time on. Either way, this time it (the site) let me in without signing up, wonder if it is the new computer I am on... Whoa...... |

Let us hope they do not all think that boat can handle stuff like that in their less experienced hands |

Interesting Video. New nautical term "barking" "Barking" is a nautical term: its the process of treating canvas sails with tree bark as a presevative. Each village would have its own large caldron and "secret formula" for the annual treatment of sails and other canvas. Now its mainly just a memory in "tanbark" sails for classic boats. |
