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 ass...

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...

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...:)

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.

http://en.wikipedia.org/wiki/Capsule_hotel

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.

Hello...

Go pinch a plastic drinking straw...

Now go get a 24" to 36" x 20 foot PVC PID (public infrastructure discharge) pipe and a couple of propane or acetelyne 'cold grave' heaters...

Take the works to the auto crusher and BOOM - there is Bob - not my uncle...

The end of the day looms near - thoughts not so clear...:)

Kinda' like a constant camber - hot molded - smash hull...:)

SH.

Easier in aluminium, run the pipe through som rollers, flatten the transom area a bit...:D :D

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...
War? What war....? Plain piracy to rob from a decaying Spain the few remaining colonies.
"Captain Henry Glass was on the cruiser USS Charleston when he opened sealed orders notifying him to proceed to Guam and capture it. Upon arrival on June 20, he fired his cannon at the island. A poorly equipped Spanish officer, not knowing that war had been declared, came out to the ship and asked to borrow some powder to return the American's salute...."
http://en.wikipedia.org/wiki/Spanish-American_War
But, because the divine justice exists, then the USA got Castro.

Cheers. :)

Hello...

Watching an ABBA documentary - not sure how I feel about that really - I never went for the blonde...

Also wondering whether the old bathtub pop pop theory could be scaled up a bit - I do not know of anyone who has tried - or maybe they did and for obvious reasons - we did not hear from them again...:)

See http://www.nmia.com/~vrbass/pop-pop/ ...

Why do my even semi serious posts always drift to the south...

Oh well - that is the nature of discussion - I imagine...
