    Hello…

    Above is a pun...

    This whole axe bow thing is such an incredible revelation - it has absolutely no preceded ant...

    My god - what a fantastic new thingee...

    My British father in law just snail mailed me a tie with a big 'W' with an anchor under it - repeated as 'pattern of print' per MacIntosh or 'motif' for the froggies...

    Christ - the Spanish vs. American war was really not all that long ago in history - or at least in American history - at least compared to Spanish history and other...

    The 'Axe bow' - my ***...

    Aaaah, SH, but to understand the axe bow "incredible revelation" fully, one must understand that it developed from an equally "incredible revelation": that, all other parameters being equal, a longer hull will be more efficiently driven and perform better in heavy seas than a shorter hull.

    Thanks Charlie, very interesting read, But for me, I think not - - of the "axe boiw" hull form... The lengthening - relative to wl beam - is a hull form demanded in long range sail, and power, for cruising cats here...

    Brian,

    I also picked up on the Ax Bow some weeks ago after a link was posted by mgpedersen on the forum about the 20th HISWA. I wondered how it would work on a cruising catamaran inspired by a Gunboat 62, which appears to glide over rather than through water. Series #4 "ICON" is lighter than the first three and it shows.

    http://www.sailinganarchy.com/general/2006/gunboat_launch.htm

    A catamaran built as an epoxy/ply composite would be somewhat heavier and might benefit from the wave piercing underwater chin, which would also lengthen the hulls. Figure 5c on page 6. Taking the bottom and drying out on a tropical island would require just a bit more care.:D :D :D I also think a curved leading edge would look attractive.

    Commercial boats have the "luxury" of a dock.

    I wonder what the chain would do to the underwater bow at tide changes for anchored cruisers?

    My kedge would match the main anchor and both would be deployed. No swinging and no scratches for me. :D

    Hello...

    Those wacko racing canoe guys played with this years ago and got it banned...

    Uffa Fox also played about with it - just bugs me when some wingdinger thinks he can slide something in as his very own fresh coffee...

    Shows a lack of research and a pound of arrogance...

    Yeah...

    Great Goodies

    Hello...

    The up of this whole axe bow aesthetic is that if it takes off we can all go out and buy a whack of large diameter PVC sewer pipe - torch it up - pinch the 'bow' together with a big clamp and have instant hulls with cutting edge - no pun intended - proof of concept...

    I think I am warming up to this...

    Thing is too - I remember Dhows - or what ever they where called...

    I am not sure that I accept butt ugly in the name of science - but I have very little to stand on with regards to same...:)

    Danske mae...

    Hello...

    May liked me frigs so much she danced a jig...

    I do not remember Denmark being south of Copenhagen ...:)

    See my gallery photos - thumbs at 90 - I loved that trip home - I have never felt 'being home' - like I did then - see http://www.boatdesign.net/gallery/showphoto.php/photo/3230/ppuser/3673 ...

    I may have missed the mark here - I tend to do that...

    It would work for smaller day cruising catamarans with a bridge deckhouse, as the sewer pipes would not offer much internal space except for bunk space like the Japanese Capsule hotels.

    Of course, we could also mention these.

    However, those sewer pipes are very tough. Forming the long ax bow and a decent looking stern would require something like a steam hammer to force the shape.

    One tough set of hulls though.
