Re: Hap's Cut goes 3D

I can compare my Goat Island Skiff's(GIS)side flares to the Hap's Cut (HC)and
form a hypothesis? Jim M will need to address the real math. ;)

My GIS has a flare of 110 degrees at maximum beam where the sides mate with the
bottom. My HC has a flare of 106 degrees at maximum beam. (dry fit and
incomplete construction) Since the flares of the GIS and HC are so close and
having sailed the GIS for 2 years now,I project the following:

a) HC will carry more rum than the GIS.
b) my wife will enjoy the cabin
c) HC will heel and settle in naturally at about an angle of 10 degrees.
d) As the boat is loaded with camping gear/people the stability of the boat will
increase.
e) the boat will remain stable/controllable/comfortable heeled to about 45
degrees.
f) boat will surf easily and in a controlled manner

I have recovered from a few near capsizes that have put the sides of the GIS
nearly flat on the water, maybe at an angle of 60 degrees, so I expect similar
stability.

These are just my wild guesses at this point. I did select the Hap's Cut because
the flares where close to my GIS and I really love how my GIS sails.

heel.

Posted a few pictures of an idea of using dual rudders and keeping the engine centered. That way if I want to use the boat as a motorboat without the sails the...

It is a good idea. having 50lbs off center and up high on the stern is not so wonderful. Off centering the rudder is awkward to use. Its lots of extra work...

I dont see problems with the concept really, they can probably go a bit closer together in actual size than as modelled too, the outboard and rudders only need...

Nice job working it out on the model like that. Smart. I was imagining before seeing the moke up, that the rudder controll would somehow be centered. Since...

Well, you've hit on most of the disadvantages so maybe here's some advantages. * Redundancy- it you break one rudder you have a built in spare. * Better...

Nice model and picture. Clever, but I do not see a good enough reason to have two rudders. One leeboard works as well as two.....why not one rudder. I...

Good that you showed a model - makes it so much easier to know what you're talking and asking about... I would say JIB has it right - but ask him if he thinks...

Look at Devlin's Litl Coot, he drew up that boat a while back and it uses dual rudders and a motor setup just like you describe. I'm considering using his...

As mentioned previously, I plan to go with the same set-up Gary Blankenship has on his Frolic2. http://www.duckworksbbs.com/plans/jim/frolic2/index.htm ...
