    M.

    I cannot get enough of the Gunboat video. I play it at least 4 times per day. Haven't you slept yet? It must be 11 AM there? :p

    M,

    Thanks for the link. That's an amazing service you have there. AFAIK, a real time coastal radar weather watch is not available in the UK. I expect someone will put me right, as the facility would be mighty useful.

    To make the boat even more fun....I flared the hulls a little more to make room for 2 more hatches. (still the same below the waterline). The space between the hatches is a dining table for a couple....you know.....dinner by candle light. It's also much better for fishing. The hull deckline is exactly the same height as a dining table (measured from the false floor).....good for sitting while eating or standing while cooking. The opt hull shape provides ample width for a floor to stand on, while the small hatches support your body while you are standing.

    Imagine watching your food being cooked by someone else while you lie back on a soft mattress.....watching the water wizzing by.

    When your head is low, you feel closer to the water like on a small boat....holding on to that 'raft on the water' effect has always been important to me.

    Can't think of how the boat could be any better....except brighter happier colours (shame Freeship doesn't have better lighting).

    I liked the Gunboat video. Gotta say though....I was impressed by the speed of the monohull!! Also, the cat was taking it's wind....but don't worry....I will never defend a monohull LOL :D I didn't know there was an age old war between monos and multis....until I came onto this forum.

    Richard, NZ is a unique place where that ******** is limited to non-existent, Where there are plenty of competitors, the mono boys seem to object loudly to being out paced. Even the Brisbane Gladstone has split (spat out the multi guys) & little media coverage too sadly - unless a disaster is caught on film.

    I would love to visit but still too cold. . . Global warming is my only hope???

    apparently NZ is supposed to be the last place that will be affected by global warming. Another reason why I'm off to LA.

    More very useful information about construction is available at http://www.mecat.com/indexpower.htm

    The P-45 regular updates for 15th October 2006 reveal an unusual (to me) underwater hull form.

    RE: Chromaveil

    To: Richard Atkin
    RE: Anyone had any experience with Chromaveil? Do you think it would fade away after one week in the sun and salt water? I like a worn out look, so maybe a bit ...

    The Chromaveil product will not fade or be affected by salt water. Those issues would be a function of the resin and not the veil. If you have any questions regarding our products please don't hesitate to ask. My direct email is customerservice@fibreglast.com.

    Have a Great Day!

    Pericles, that is very similar to my hull-form, except the hulls are so close together it may as well be a mono!

    There must have been something different or not using hull optimisation (I doubt that would have been missed).?????? and 22800jbs is 10.3 tons & mine is 7.5 metric tons? I dont understand - Pays to read the whole article - instead of going off half cocked.. :D :D

    It still seems to have huge hp (2 x 160 hp volvos) Back to my numbers.... & some more model testing, just to be sure!

    M,

    The P-45 is 42' 62 LWL and 18' beam, but it's value to you and me is the acquisition of knowledge, as always.:D

    Take the matter of weight. She's built by vacuum infusion of Core-Cell with catalysed vinylester, which indicates to me how heavy that method seems in comparison with Epoxy/PVC foam. Gunboat 62 is carbon-Kevlar-epoxy. I am quite saddened that the OSSA diese lelectric trial was not satisfactory, but the 160 hp Volvo diesels do give 25 knot performance. if required. We live and learn.
