Driving home from work :( the other day and passed one of these style boats. Maybe I've seen them on the water and didn't realise what they were capable of but I've never seen one doing 100K's down the hi way before. This is a picture of a similar boat I googled.

It's a long shot I know, but can you recall what was towing it, what colour the boat was and how big it was?

Grey-ish Falcon wagon, white boat about 7m long perhaps?

I've been thinking about a stitch and glue single chine catamaran around 8 foot long as a tender for my boat.( shaggy could make one the same width as his boat beam and make it foldable using a dolphin striker on either end to hold the weight and crew when its open
using a ladder as a means of making the centre beam.
below two dolphin strikers on aft the same forward as in this photo below supporting there mast



adding a offset ladder down the centre so when you pick up the davit lifting points
( your two cross beams on either side would not be even length) meaning if one side was fixed the ladder other hull would fold up so the










much like if you placed one hand on top of the other

so if one hull and cross beam was fixed to the offset ladder when fitted via the davits the two hull would fold against each other
so the beam of your tender when raised on davits would only be the length of one hull and the ladder centre beam. But when open it would add the complete beam.
To me it means when sailing no water or rain can be captured inside the boat
So I could have a one hull and beam and ladder of 3 foot but when open it adds toe extra feet making the beam when open 5 foot or what ever suits your boat.
add some hard wood to the bottom of the hulls so you doesn't wear out the flat bottom hulls add you low 3 HP out board and it will move along at a reasonable speed
So open it would work like this video below but with a wider beam closed it would fold up one side making it as wide and the height of one hull basically

Sorry Chris, Can't remember the vehicle. I only had eyes for the boat. It was white with blue under the waterline. I could not see the gear that was use to hold the hulls in position once it was in the water. I don't think it was as big as the one in the picture and may have been in the 7+m range. I don't think the tow vehicle was anything special as I can remember it slowing a bit as it climbed the hilly roads on the hi way near the Sunshine Coast.

CT was wondering whether it was my version. It lives in Lake Macquarie and is 7.3 metres long. Floating it tomorrow to do some work on a new back beam.

cheers

Phil

I think it would be way too big hanging off the back of a 28 footer. Davits seem to be OK on 50 foot plus boats but under that they strike me as being a hazard in a seaway. Catamarans are fine as tenders. I use one made from a 14 foot Windrush. It lives on a trailer and is an excellent work platform, the hulls fit up nicely either side of the stern of my Currawong 30 for windvane maintenance etc. Good for carting my hookah gear and diving off. 8 foot catamarans would not have much load carrying capacity and would stick out way too far each side of the stern of a H28 and surely catch the odd quarter wave. I have an inflatable which I have never used, too big and heavy to stow below. I think your best bet is a small 2 piece hard dinghy and an inflatable kick boat for warmer climates.

An other thought was buy a couple of these they were on special the other day for around $300 and bend up some tubing and use the hull through drains to form a cat dissemble when sailing long distances.
short day trips leave it assemble
These have 8 through hull holes per kayak so I could use it for both tasks as a kayak or assembled a tender to pick up water and food
Hang them like saddle bags over the cabin
I do not want any thing over the front hatch

and perhaps find an Asian country to make them out of cane bent and supported with cane ar lar natural and employ them. So they can feed them selves and have a better life

Then find another nice lady to make me a trampoline net
A happy wife is a happy life There is nothing worst than a wife's scorn


and get high tech and add sister clips so it can fit onto the cane cross members I might even buy a bimini top while on line the right measurement
nothing like a straw hat

roll it up when its not needed
Or make it out of this it would make a great shade over the boom on a hot day be good for side shade on a bimini to $42

I would be checking out the various kick boats on Alibaba.

No worries, I thought it might be Kankama's and you may have noticed that it wasn't being pulled by the usual huge 4WD. Cheers.

Passed the same boat being towed Sunday arvo along Mooney Mooney bridge, about 15min north of Sydney.
