Boatman...That's just like you to delve right into reality!

Re: The Flyin Hawaiian is gone!

For me this story raises an interesting question. Can amateurs design and build seaworthy boats ?

Do you know of any boat designers that have designed and built an ocean going catamaran without having a naval architecture degree ?

Is it plausible to design and build your own ocean going catamaran if you use tried and tested design principles and build processes ?

I don't think James Wharram is a naval architect.
There were some pretty large catamarans and proas used by the Polynesians and early Europeans over 2000 years ago. These traveled long distances regularly.
So, I think it's very possible to design and build your own cat. There are volumes of data and info on the internet along with West Systems (pdf) books and many others.

The guy that built this big cat chose to ignore all of this free data and do it his way. His name is Hot Rod btw. No ****!

Depends on size. Multihulls pretty complicated vessels to design and bigger it gets more complications arise.

There is "some" difference in designing and building 10' dinghy and 50' sailboat.

The main issue is the bridge deck to hull connection. The complicated part is that the mast sits right in the middle of this. On a mono the mast frequently goes all the way to the keel but this isn't possible with a cat. So you have your wires (stays and shrouds) pulling the mast down to keep it straight plus the forward pull of the sails creates quite a bit of stress at the mast base.
The other issue is that the hulls want to splay out if not properly braced. Wharram did this with wood poles or beams just like the Polynesians. Typically the beam runs from the outside of each hull to the outside of the other hull. Keep in mind that your mast cables (shrouds) that usually attach to the outside of the hulls have a tendency to pull the hulls upward. That full length cross beam prevents this. The Flyin' Hawaiin does not have this so the hulls are splaying out without even a sail attached.
DOH!

+1. Smaller is easier if "winging it"
Here's a pic of a 65' cat with those big crossbeams. Notice the mast sitting on the front one. This is what the FH should have.

Sticking a bludi centre cabin that connects to the hulls and not just sits on the beams independently.....
IOW a floating condo....

Re: The Flyin Hawaiian is gone!

Catamarans like the Flyin Hawaiian are just so 90's. What you really want is this XENOCRAFT x-50:
