Trailerable Multihulls

Hello Richard...

Hmmm... I envy your crazyness. Fffar out? It wasn't that cool or fffar out when it was happening. I can't remember exactly but I don't think I got back in the cab for several hours until my hands stopped shaking. I still get nightmares over that and it's been a long long time. But, I survived it and it did put me through school, so, I guess it was my time to be blessed, although it was one scary life awakening moment.

The trailer extension is not ruled out, but this is still way out in the future. I am still kind of glad that it is getting aired out in here though.

Thanks
J

 

Richard,

Not a hijack at all. Those take the entire thread.

I think you might be looking at Reynolds? The R28? I remember reading that it didn't get off the ground, but there is a prototype out there somewhere!

Cat 2 fold is also looking for investors for a smaller 28 footer. Can't remember where I read that.

That's all I can really offer off the top of my head that is along the lines of your design.

Its not too bad towing a big cat on the road,my mac 36 was a long load but fairly light,about 4000lbs for the loaded boat and maybe 1500 -2000lbs for the trailer,low, probably only about 8ft and under 8 ft in width,but it was long at about 42ft with the trailer tongue. One issue i had was that the boat had inboard rudders which could drag on the road going in and out of gas stations,i usually left them in for short trips but for longer trips i would back the sterns over a drop off and remove the rudders.Other than that it towed at highway speeds and was very stable. It was no problem launching at most ramps without a tongue extension i think this was because the transoms extended well past the back of the trailer.

J,
losing control was not the cool part....the way you dealt with it was. As for carrying nuclear warheads and stuff.....that's kind of cool in a movie kind of way.
I was involved in a major accident on a push-bike when I was 11 yrs old. A friend was pedalling and I was sitting behind him on the carrier. An old man who was not able to drive his car safely, ran us over and I was the one who copped the most impact. Took a long time to heal physically. I know what it means to be in a scarey moment....not cool.

Steve,
I'm glad you mentioned that. I thought my 28 ft cat would be an unstable load and I would have to drive REALLY slow, but I guess it's not that bad after all. I'm looking forward to finding out.

 

Hello Steve,

Glad you brought this up. The rudders (inboard) for the TR27B look like they will have an approximate draft of 2.7 feet. That will mean 1.25' below the keel which will place them very close to ground level. If we make them kick back, then it should be okay. If not, they will have to come off which is going to take away from the initial "pull up and drive" concept. Not acceptable.[/QUOTE]

Thanks,
J

 

Not the best shot but if you like inboard rudders but want them to tilt you could do worse than studying Bob Oram's rudder setup.

Hello Richard,

Shipping manifests for military convoys were never given to a driver and drivers were never given information on our load because we had an escort that took us where we were headed and an officer carrying the bill of lading, but I don't think I ever hauled nuclear weapons. Those usually require closed roads and a veritable escort which may include a small army and helicopters etc.

No. Not cool at all. I'm glad that you were able to recover from your injuries. Lots of danger out there. We have accepted comforts to life at the expense of risk to life and limb too readily. It appears that heightened caution will be a way of life for us. Ergo, my heighted paranoia completely justified as evidenced by having reached a mature age.

I was thinking about the tongue extension and it may be nice to have as a "telescoping" option down the centerline of the trailer so that there isn't 10' between the trailer and the car, but I don't think it will be needed. Given enough rear overhang most times it will be okay for ramps.

Since you look to float off on the beach, you may want it because the slope of the beach falls off shallow and you may need to get into deeper water. Unless you lay her down at low tide and wait? Do they allow you to splash on the beach when it requires a vehicle? I have never seen it done at any of the beaches I've been to here and suspect the Dept. of Parks or Environmental Protection will issue a severe fine if not arrest you.

Thanks

Hello Mbz,

Very very simple. I was also looking at the set-up from Richard Woods as a guide also. There are so many out there that has already been worked out that it will just be easier to trust their record and follow suit for the simplest most effective set up that may fit the TR27B.

Are my eyes deceiving my depth perception? Why is the tilting base so long? Do you know?

Thanks
J

 

I think it is just to keep the rudders as far forward as they need to be. It does fit the transom when down, you can't really tell its an insert when its in place, at least in the pics.

 

There are some guy's building Oram 44c's somewhere on the forum, mebe they could post some pic's or diags. Ask Masali, he might know who they are, I forget.

 

Not just Oram

Gday guys,

The cassette idea is used by almost every designer in Oz for cats that don't have keels. I have themon my Chamberlin. All it is is a cutout section of the stern that can pull out, with the rudder embedded in it. It is way harder to build than a rudder box and much harder to pull up and down. If you are thinking of going into shore a lot then doin't use this idea.

You can steer with the rudders half up - especially if you use lifting dagger rudders. Cassettes lock everything in place, of course you could always lift the cassettesa and go in under power.

Cheers

Phil

 

Read ya Heinz, I will be going around there this weekend for a looksee... Hope to get some pics to post...

 

Oram was the only one I could remember of the top of my head Phil. I have never tried it but the setup doesnt look that hard to use, a bugger to build maybe.

That'd be good M!

 

Just got back from my friendly builder of Bob Oram boats and was politely asked it I would suggest that any interest should be directed to Bob Oram, or at least purchase the drawings for the rudder assembly from Bob as that is his livelihood and would appreciate a little reward for his efforts.... and I am inclined to agree.... It is a carefully thought out system that works very well...

Any interested parties please email or phone Bob - he is very personable and very willing to work with people in achieving their objectives...

 

Respect that M, a decent picture would not hurt though.
