Thank you Willallison, I am well aware of the difference between catamarans and monohulls. I have done plenty of research on fast displacement...
@ erik818 "significant lift from anything but displacement of water" - please explain. Dont all semiplaning and planing boats generate lift...
That is definitely not a displacement cat. 18kts on a 47ft WL gives a Fn of 0.8 definitely in the Semi Displacement range. I am sure the boat...
Update: I have developed my design a bit. The section shapes of the demi hulls are now much more semicircular in order to reduce WSA. I am...
The boat will be around 75ft long. no i have not seen your videos yet. ~Dave
thanks for the comment. The construction will be strip plank wood epoxy most likely. Also I am going to play around with different bow...
thanks so much for the help. here is a preliminary lines plan of one demi hull. let me know what people think. comments for improvement are...
I need some help with power catamaran hull design. I am a NA student, and am trying to find information about hull shape and resistance...
I have not. However I am interested in learning more about catamaran design, and predicting catamaran resistance, especially for power catamarans...
Hi mwysn, congrats on going to the Landing school. I went there a few years ago. I can get you a quick planing hull in rhino if you like. can...
PS. thanks Leo for your reports. this is very interesting stuff. ~David
I am a yacht design student, and last year we a tank test on an NPL series hull. i would be very interested to see the results of this CFD done...
very cool. I would be interested in finding out more about this.
I am a yacht design student on summer break, and have lots of free time on my hands. I can easily create a 3D model for you and help with...
Hi, I was wondering what the best way to design a cat would be. As most software (Maxsurf, Fastship, the two I am familiar with) only design...

Also how do z-bows compare to other cat hull bow shapes, such as wave piercing or standard or just super extended
thanks for your replies. I am aware of the look and shape of the zbow. I know it is helpful for pitch damping especially for semi-planing hull...
Hi, I was wondering if anybody know more information about z-bows
If you are interested in Design you might check out the Landing School. They have a quick one year design program. This is not a theory based...
