Good Day, Captains,
Does anyone know where can I get the "trailer" in this picture?

I don't need to take it onto any road or highway, just for moving a boat in marina.

By the way, is it called a "trailer" or something else?

Thank you very much.

Looks to be a specialized hydraulic lifting trailer that is towed by a tractor and is able to raise the boat ro put a cradle under then lowers it on. Only ever seen them owned by marinas, as quite pricey.

As Downwest says.

If you don't need the hydraulics which probably allow it to be adjusted for a variety of boats go for a yard trailer, either with adjustable pads or made to measure.

Simple wheel bearing with wheel usually straight onto axle. Simple steering mechanism at the front. Designed such that boat can be floated onto them on a slip and towed at low speed a short distance around the yard. No reason why boat should not be craned on if desired.

Search for Boat Yard Trailer, Yard Trolley, Bomb Trolley. Try talking to boat trailer manufacturers.

Thank you very much for your information.

I did not know that one is equipped with hydraulic lifting, I thought it is just a simple trailer for marina use only.

Those key words, "Boat Yard Trailer, Yard Trolley, Bomb Trolley", very important to me. Thank you so much.

I built one using very heavy castors and steel box sections. Can be moved using pinch bars to adjust castors and then it pushes very easily. Depends how far yours has to move.

I also built one using the rear axle from a Renault Master and the front steerable axle from a LDV truck. Bit joining was two RSJs with the keel between. Boat 27ft and 4.5 ton. Used in fresh water so not so worried about bearings. Bits came to about €600.

Hi PCUK,
Would you please provide me some pictures of your trailer? I may want find a local factory and to mimic one.

My boat is just 28 feet, no more than 5 ton weight. The maximum moving distance is about 100 meter, usually 30 ~ 40 meter.

Thank you very much.

A few years ago there were lots of trailers around not unlike these. They were ex MOD bomb trailers for carrying bombs up to the undersides of low aircraft. The hydraulics on most had long since failed/been stripped etc. but the remains did make a sturdy low yard trailer.

In many ways I was sorry to see them go, something from a different age.

They were called SABTs, Standard Airfieled Bomb Trolleys. There were plenty on the UK South Coast.

If it helps, here is a picture of my launch trailer. My launch is only light ( 1.2 tonnes)
However, one can beef up the sizes to suit. The front & rear axles are steering axles from old lorries. The 2 main carriages are RSJ's & the cross beams are box section.
the uprights are galvanised scaffold poles with swivel couples so that they can be adjusted for rake. They slot into the hollow box section cross members.
The wooden blocks mid way are designed so they are hinged inboard & wedges drive in from the outer ends to adjust when the boat is on the trailer.
