The ride suddenly became very rough with (our recollection) of a maximum of 3 foot seas. I was looking forward inside the cabin and noticed water continuously breaking in front and spraying way above the front of the boat. By the time the captain turned the boat and started heading back, all four individuals above were completely soaked. As my wife recalls, "It was very similar to a wet tee shirt contest." "All three guys and myself." Perhaps the captain didn't know how to approach and turn the vessel, perhaps not. In any case, when we debriefed that pm, we said NO to the Lagoon 43' because of the great amount of sneezing, wet ride, ________________________________________________________ Brian ask: So you definitely feel that you have buy now had your Aventure vessel in very similar seas as you experienced with the Lagoon 43, and there is a very different and positive advantage to your present vessel's capabilities??

For the benefit of newcomers to power catamarans, could someone please explain "sneezing?" --Georgs

Let me try. When a catamaran is in motion and when a wave of any type enters between the sponsons the wave typically becomes trapped, broken up into smaller water particles and the new air/water particle mixture becomes compressed as it travels toward and egresses the aft end. The mixture accounts for the very comfortable ride a catamaran displays in rougher seas since the mixture and hulls act together like a giant shock absorber. However, depending upon hull design, sea state and speed of the vessel, this air/water particle mixture can develope a counter pressure high enough so part of the mixture may not egress aft. A part of the air/water mixture can be pushed forward and escapes by coming over the bow. Hence the so called "sneezing" phenomenon. The size of a sneeze can be anything from a light mist to a heavy raindrop downpour and often is a combination of both. The Lagoon 43 sneezed a lot on that particular trial day. In the 18 months we have been aboard our Aventure 460 and having cruised over 7800 miles, we have "sneezed" only one single time! One single sneeze! The sneeze had the audacity to came up to our flybridge. Our hardtop flybridge is enclosed on three sides with 7 and 9 mm CE certified safety glass and no one got wet. This was in a head sea with about 5' waves. The downside of this event is that I did have to wash the salt off the windows at our next port of call... :))) Pierre "Yum Yum" Aventure 460 Power Catamaran -----Original Message----- From: power-catamaran-bounces@lists.samurai.com [mailto:power-catamaran-bounces@lists.samurai.com]On Behalf Of Georgs Kolesnikovs Sent: Wednesday, March 16, 2005 6:52 AM To: Power Catamaran List Subject: Re: [PCW] Back on boat...
