[PSUBS-MAILIST] To Risk Everything21, Re: 18 ft Hobie hulls. Bill Akins.



Thanks Risk for that hobie cat hull offer, That would be great!
 
 Where are the hulls located? I live in Hudson, Fl. but if we aren't too far apart I could come get them with my ford van if seperated or a flatbed if they are attached.
 Are they in pretty good shape without any fiberglass rot from too much exposure to UV? Is the boom between them attached or are the hulls seperated and if so is the boom still laying around detached?
 
I don't know what the completed weight of my wetsub will be yet,
because I have not yet purchased the 4 batteries to go into my battery pod, nor have I worked out any possible buoyancy problems and added any needed ballast yet
to the battery pod. Still working on it. But I would estimate approx that when everything is done my wetsub will weigh in the range of perhaps close to between 500 to 600 lbs
without anyone in it. With one operator in the wetsub to steer it while being towed it would increase the weight by the total of the operator's weight so
might as well add another 175 to 200 lbs depending on the person of course. So in the end I would estimate a weight of around 800 lbs on the high end of the estimate and 650 lbs on the low
end of the estimate.
 
Think those hulls would support these estimated weights?
 
Kindest Regards,
Bill Akins.

Bill,
 
I can get you some Hobie 18 hulls from an abandoned boat. Finding beach-cat style hulls in the 20-24' range will be very problematic. You would likely be better off finding a pontoon boat with the aluminum cylinder hulls.
 
Also, beach catamaran hulls are extremely low-buoyancy. They depend on waterline ratios of 11:1 or greater to achieve their high speeds (they're displacement craft, not planing craft). Even the 20' boats have hulls that are only 1' wide at most, and that is not at the waterline. I'd have to know how heavy your wetsub is to tell you if it can be floated by a Hobie-style hull

But as I said above, I will not be using a system like that to launch it. I'm currently on the hunt for an old hobie cat sailboat neglected in the weeds of someones
yard to modify into what I described above. Something between 20 to 24 feet long would be nice. I intend to construct a small enclosed deck behind the underslung sub for the
motor operator and some dive gear as well. This is a relatively cheap and safe means to get my sub to the dive location where I will not exceed 100 feet.
