It a rare one, but I am looking to buy a Red Baron multihull trailer sailer. They were originally made in Perth and are a sturdy little multihull with a very small forward cabin. They are usually just a bit over 20'..., I can pay a reasonable price depending on age, condition, modifications and extras, If anyone knows of one for sale in WA, can you possibly let me know ?

Could you get a used "normal" boat trailer of suitable load capacity and add on the bits and pieces suitable for it as reverse engineered from these photos? Not sure what WA trailer rego requirements are as regards modifications...........

This one's in QLD, not WA, but it provides something of a comparison.

Quoting a reaction on the other website that I am not supposed to link here, in response to the question "Are they trailerable" ...
"Yes, they are trailerable.
No, the trailer isn't an off the shelf design. But it is at least simple.
They're slow as a wet week and no more space inside than something like a Dennis.
Even with a trailer it's hard to see more than five or six thousand in one."

Drifting - Jarcat a much better option,but have to keep in a shed/under cover .
Had a 5m for years but access/storage was an issue ,and stayed dry for too long. Was like a piece of furniture,and home built by a tradesman,who enjoyed the process of construction,and then moved on to a Farrier,for some complication !
Light,and lovely to sail,but not to windward - ideal for the Whitsundays,which was the dream = regret !!
