Shanty Boat

[KevinR]

do a search for "Yukon Delta Houseboat." It's small enough to trailer easily and large enough for a couple or small family to camp on the water. They are also quite affordable. I want one.

Hi jstrubberg:

I apologise for starting a new thread.



I realized much later that this link belongs here. Perhaps one of the administrators could combine my thread into yours. . . .

Thanks all for the neat info on caraboats etc.

You mentioned something on your experience with pontoons have a tendency to dive in choppy water. Please elaborate on that if you can and explain that. Just thinking out loud, . . . " do you think a twin hull is more stable . . . Less likely to dive as you say? "

Thanks

I wonder if you could modify or use or emulate one of
the ice shanty trailer chassis to achieve the 'Float Trailer'
effect on a shanty boat hull ?
e.g.:

Just build it on one of these ?

[milliejohn]

I could add pontoons to mine

I don't know how well this converted pontoon boat would do in the water but it looks good.

There are some interesting builds out there on pontoons.

I really don't like the way pontoons handle waves, though. They tend to go through them rather than lifting over them, usually leaving you with a half-swamped boat. Maybe others have better luck with them than I do.

I'll go into this a little more since Martin asked about it above. It's really all about how many square inches of hull you have in the water. When a solid hull hits a wave, the wave acts across the entire wetted surface of the hull, and in most cases lifts the hull over the wave. Pontoons have much, much less surface area, so they tend not to lift, but to penetrate the wave instead. The result is a lot more water washing over the deck on a pontoon boat than on a mono hull. Cat hulls would fall somewhere in between, tending to lift once the wave contacts the mono portion of the hull.

Of course, there's an advantage to this as well. Since pontoons have much less surface area, they are much easier to push through the water. They won't plane, per se, but getting a pontoon to 6-8 knots takes much less power than a mono hull of the same size does. It really comes down to your intended usage. For floating totally protected waters or sitting at the dock, pontoons are more efficient and much cheaper. If you expect to do any large lakes or coastal waters, well, you won't see many pontoons out there. Even large boat wakes are problematic with a pontoon hull.

It's a shame, I could probably haul off three or four set of pontoons for nothing but the cost of my gas.

[Martinup]

Thanks Jt that is something I can understand.

A question from a non-boater:

Could you gang 4-5 pontoons together to get the
single hull effect, or would they still act like pontoons
and pierce the wave(s) anyway ?

Cheers,

The more pontoon you add, the more you tend to ride over the wave. You lose most of the advantages of a pontoon, but if you can get them dirt cheap, it would still be a viable approach.

I know with my tiny house build I have looked at how some shanty-boats were laid out great resources

[Martinup]

build atop an ole john boat. flat belly hold lots of weight. you can weld an under carraige to so the wheels are incorporated. good place to start eh

Cat hulls would fall somewhere in between, tending to lift once the wave contacts the mono portion of the hull.

I appreciate and have an better understanding . . . A blend between the the above two hull styles I believe is called a, " Tunnel Hull " Someone please correct me if I am wrong on this ?

IF I put a larger motor, providing more thrust; on the back of my, " Tear Type Carraboat ", with wheels configured in to it some how ? ? ?

1 ) I would probably be using fuel very inefficiently at slow speeds and remain stable and in control ? ? ?

2) AAND then when at higher speeds I would start to plane better but also have a much more easier time pushing the boat and therefore in actuality get better fuel millage. Or more efficient use of fuel right ? ? ? I would go a further distance using less fuel.

Questions:
A) Would I still be safe and in control of the boat?
B) How might the boat handle in rough water?

I am asking for advice from all who are knowledgeable. Please weigh in on and kick it around.

Thanks Lance and JT. I Look forward to what you design and build.

I have recently joined that, " Bateau2 boat builders forum ", as well. Thanks for the referral.

[droid_ca]

if possible I'd use a jet on the prop and if you go with a bigger motor just extend the floats back a bit further to make up the buoyancy for the extra weight

Re Pontoons IMHO:

Pontoons are narrow. There is less width in the wetted surface area for the buoyancy rating than a full bottom boat. Choppy/waves have less solidity/support than a calm sea and the pontoon 'falls through' them to the more solid water. A wider hull does not cut the waves but has a greater tendency to ride/flatten them.

Its a very subjective description but essentially correct.

Doesn't need to be any bigger than a large teardrop.
