Travel cradles

I need to build travel cradles for the Skoota.

The cradles would ideally locate under BH1 and BH5.

There are a couple of concerns...

1. I built a wood cradle, but it can break or fastenings can fail..

2. I can get a metal cradle made, but it would be heavy as hell.

3. Should the cradle fasten to the boat to avoid it moving for and aft? It could connect up onto the beam socket, but would be a lot of work to design/build that.

4. What about building an all glass or foam and glass cradle? Seems like a no brainer

Any thoughts are welcome.

Here is a side view of a current method. This is certainly not usable on a semi. To keep this cradle moving for and aft or more so the aft cradle falling off, we joined the two cradles with a long timber. You can see it laying there off and out of the way.

I'd vote for the foam/glass cradle...after all your experience should be a breeze :D

Design for 1000# static load.

Dynamic?

See if you can talk to the Class 1 power boat owners, here are two on trailers. They may have a plan, idea and/or someone who could really help you.

Can the two hulls fit side by side on the road?

If so, how strong are your sockets? Could you build transport beams that integrate with your trailer?

Sort of a road worthy spin off of this concept,

Yes. The two hulls can fit side by side on a semi trailer.

The idea to beam socket them together is interesting and a novel thought I had not considered. The funny thing is I have one unusable beam that is 9' 6" long that could be cut in half and used to stabilize the two. It would be 4' 9" in half and long enough to strap into the BH5 and BH1 sockets.

Of course this just helps them on the truck.

On the ground, these stands could also help with the assembly. The crane would lift the hull off the semi and ideally set it down on the attached cradle. Then the cradle could be moved or raised and lowered to level, although the primary function is to support them during transport.

If I don't keep on with the painting; it may never matter, but the next few days are a bust.

Those are pretty common up here, although I don't think I have seen one where the sides of the lift power extended out like that before.

Ours is on a ball hitch that we hook up to a tractor and the tractors hydraulics. Our width adjustments are purely manual (square tube sliding inside of square tube).
