  • Catamaran vs. v-hull?

    Hello, Does anyone know the similarities between a catamaran vs. a v-hull? I am in the process of buying a new boat, but I have never rode in a cat before. If anyone has some insight on this, it would be greatly appreciated.

    I have always owned deep-V's for use in salt water because that was the best design, UP TO the emergence of the catamaran. The cats ride much smoother in rough water and you can run faster than any other design that I know of in choppy water. They're also more stable at low speeds and at rest. I suggest you check them out thoroughly before you make a final decision.

      This will depend a great deal on what the boat is being used for and what size it is. We need to know more about how you expect to use your boat.Kelly Cook

        I don't much care for the looks of a cat but that may be off shoot big time by the ride. The only downside that I see is that handling with one motor out may be difficult as they are so far apart. Also the ones I have seen require a specialized trailer due to the hull design.

          SeaNile, I've ridden both in rough water and the cat definitely is a MUCH smoother ride. Storage space however, is at a premium on the cat.One thing you will notice is the price difference. A cat setup will typically run about 40% more than a conventional "V" hull. If you plan on fishing, I would recommend the "V" instead of the cat. I was with a guy on his cat when he hooked a tarpon. He was in the bow when the fish ran fast under the boat. Not quite sure how, but the line got caught between the two hulls and got tangled. Bottom line, he had to use the length of the rod to try to work the line out from under one of the hulls. They sit quite deep when you're at a full stop. He wasn't a very happy camper that day.I would recommend a test ride in both. See how you like the ride vs the price. That way you can make an informed purchase decision.Good Luck on your decision Nav

            The cats are reportedly more stable on waves due to the balancing act of the 'two' hulls. A deep vee may list as it rides up the front or back of a wave (unless taking the wave head-on) because the single hull will remain perpendicular to the wave's diagonal surface and roll with the wave. A cat will remain more level because it will have one vee taking the wave at a time while the other stabilizes. The cat will 'cut waves' in this manner. If the waves are very large in proportion to the boat, of course, this effect will diminish as both vees are riding up the same wave.I'm on inland lakes exclusively so I only see waves as large as 2'-3' whitecaps or so, but while the rest of us are getting our butts slammed around in vees the few cat owners are going all out like they're on glass! Cats seem to be at a huge advantage when going fast (very fast)in rough water.Again, my experience is limited to inland waters/small boats so...

              if you can afford it i would get a cat, the only down side i would see is turning in an unexpected high sea swell. but then any boat is a problem. one motor shouldnt be bad either, look at pontoons they are just lighter but same priciple. you will also be suprized at how stable they are when people are moving around. im 170 and my fishing bud is 350 when he moves on my trophy i hang on. thats when i wish i had a cat.

                I've been considering a Cat hull. Seems as if their owners really love them because it's hard to find 'em used. They have everything I want: more room on deck and below (in a WAC)for family/lake and a better ride than deep V for choppy water sea fishing. But, I can't quite get over the look of them and the seem so pricey. I'm surprised there are not more topics on Iboats debating the cat hulls versus V. Seems to me like a these boats would be more popular. I'd like to hear some of your opinions about these hull designs and the pros /cons.

                  I have been doing a lot of research on World Cats. Despite the note above these only draw 12 inches of water with the engines tilted. I agree about the handling in chop, but one of my biggest concerns is how flat they turn . . . Seems like you could throw somebody overboard if they were standing before you went into a turn This is obviously more of a problem with a higher speed boat, so may not be an issue for you. Check out this video of a 27 footer. Looks like fun to me!!! World Cat 270SD Video

                    Hi all, I have had "V" (mono) hulls for ages before I had my first "cat" (in about 1980 I got my first) now I would not even consider anything else if you are after a fishing boat,not too good for a ski boat though, the advantages of twin hulls far out weigh the disadvantages (and there are a few)good things are stability, ride, space (the boat is basically square) twin motor safety,very easy to control in marina as the motors are a long way apart, easy to put on and off trailer, even a newbee can drive on and off if necessary, a few downsides, initial cost, usually big to tow and store, not real good on tight turns like you would if skiing, (they lean outwards like a car)and maybe a couple of other small things but all in all the best by far for a fishing boat

                      if anyone is remotely interested just send me an email with any questions I may be able to answer as I have spent thousands of hours on cats of all sizes doing all sorts of things from abalone diving ,game fishing and shark fishing, don't claim to be a marine expert but have spent a lot of time on the water in twin hulls. noelm@uow.edu.au

                        If the twin engines placed so far apart offers good manuverability, how come the the boat would not turn as well as V at speed? I'm asking because I intend to use it in the lake for skiing with the family.

                          because they tend to lead outwards when turning at speed, you can turn but nowhere near as tight as a V which leans inwards, if you want to turn around in a harbour or something, one motor in forward and one in reverse and you can do a turn in your own length (like a v but much much easier)

                            a high speed turn can of course be good fun (and exciting sometimes)

                              They turn well at speed, they just turn flat . . .If you have a boat now you know that a V-hull banks into turns naturally. This helps to keep all of your passengers seated when you turn. You would not believe the difference in a high speed cat. They literally stay flat. It is quite noticeable if you ever get a chance to watch one.So imagine your observer yells "down" and you take a quick look for traffic and then turn to protect your skier. Well imagine this with one of your passengers leaning over into the cooler. With a v-hull the beer, the ice and the passenger all benefit from the banking. In the case of the cat hull, everything wants to fall over or spill out as the hull stays flat and the direction changes. I personally think it could be pretty dangerous, easily minimized, but I think the opportunity for injury ultimately goes up . . .
