Are there any clever and effective ways out there for moving heavy and large model boats - from the car to the water and into and out of the water? I have a small folding trolley cart for lowering smaller boats down vertical slopes but the big boats are another story. I was at a funeral recently and the coffin was wheeled along on a cart which could be raised and lowered. Expensive, cumbersome and slightly morbid however. Any suggestions appreciated.

Sandy1000  stay away from the funeral parlour  those coffin trolleys are 24 volt DC with self contained hydraulic systems

However they were designed by accountants  who scrimped on the cylinders as they chose ""phasing cylinders" ........just like the types used on VALMET shipping container carriers

The rod side discharge on the first cylinder is naturally of smaller volume on the blind side .....so.....the 2nd cylinder is of smaller bore.....then the same  applies to the 3rd  & 4th cylinder

If any one of the four cylinders suffers from internal bypass the coffin can tip & fall from the trolley.......now you wouldn't like that if your large heavy vessel was suspended above....... .....Derek

Thanks for that. Any other ideas? The boat needs to be lifted from the car, carried to the water, held at waste height, for final preparation, the lowered onto a wheeled launch ramp and later the process is reversed for departure.

I have the same problem ...48" Mister Darby..plus anothet 40lb combined of battery and ballast

theres no other wat to put it

"brute force and ignorance  " with a little finesse.

In advance, sorry guys couldn't help myself, but a boat trailer springs to mind

One of our AMS members has a model of the USS Bowfin which measures 12' (144") in length and 5' (60") in the beam, and weighs far in excess of a quarter of a ton (minus ballast).

He transports this monster on a custom built trailer behind his car, and launches it like a full size boat...ie, by reversing the trailer into the lake down a slipway and floating the sub off. To land the thing, he drives the sub into position just behind the trailer and then pulls it back up and onto the trailer by hand.

This beast will be at Brighton Modelworld Show next year, by the way...

How about a modified scissor lift table?  http://www.rotairsystems.co.uk/liftmate_scissor.html

Or a modified motorbike lift: http://www.workshopping.co.uk/category/motorcycle-lifts/488/?gclid=CJPMk9bl-KkCFcRO4QodwFVaWA

I use a extension ladder inside my trailer to move my models allows them to side out and a 12 volt winch pulls them back up on the extension ladder roller skates wheels run up down the ladder  and a custom made trolley slips in and out of the water tassie48

The scissor lift table are ideal I will look around locally for something similar. The wheels on the motor bike affair are too small for the sandy and roughish approach to the water. Thanks.

Any chance of a picture? Regards.

This might help as well,

Also, you could use a 12v motor driving a lead screw to raise and lower the table.

When the paramedics get to the hospital and they get the trolley out of the back of the ambulance the trolley legs complete with wheels fold down and lock in automatically. If you can find one of these, maybe it can be converted to carry a boat.

I don't know what you call "large", but at least one of my models weighs in at nearly 120lb (on the water), and another one or two are in the 90lb range. I have to transport them in a trailer. But getting them out of the trailer and into the water is really quite easy.
The models are made so that interior access is large, and so spring loaded "chest" handles can be fitted. The empty "hull" section is then easily carried to the water. Then the batteries and ballast are added ....and then the "top hamper" plonked on. No individual part weighs more than 30lb. BY.

I have come back to this post as I am considering trying to make my own. There are plenty of lifting devices, scissor lifts etc out there but they usually have small wheels and what I want is something that has:
Large tyres to go over rough terrain down to the water's edge.
Low profile to fit in the car (large tyres notwithstanding)
Raise and lower capability
Water resistant ie allows rolling down into water for boat to float off

Also needs to be steerable. I knocked up a launching trolley out of slotted angle iron but found it awkward to steer. Also tyres are too thin, even though I doubled them up.

Mobility scooter wheels too small ? They are available in various sizes and are pneumatic. 

[More Coffee]

This is how Stena does it..

[slug]

how about a car engine crane on bigger wheels you can get lightweight ones  just athoughtslug

machine mart do a sack truck that could be handy nocst12 slug

This is for small boats, epecially for vertical edges.



For somewhat larger boats the trolley (only $29.00 at the local store) laid down and with a handle fiitted into the plastic tube is another approach while the upgraded launching trolley is a limited method - hard to steer, wheels too thin.
