launching aids


Someone, somewhere out there must have the ideal launching system for a four foot long, 18lb boat, that wont break my back each time I bend down to launch it. I've tried motor fan belts but they damage the rails/stanchions on the boat. There must a myriad of differant systems being used. Please share your ideas. Thanks.

what I tend to use is along the same lines, but consists of two lengths of 5100lb breaking strain ratchet strap webbing stapled to two lengths of timber about 12" long, then gaffa tape wrapped around the wood to prevent splinters.

I have used them for my yamato, and they have done NO damage. they are also long enough so the straps when lifted at waist height mean the model is just above the floor, ideal for lifting down to a canal

Look under "sailboats" and "square rigger kit". Down a few posts it shows a launch cart, kind of like a small hand truck. Something like that may work.

Mndsw, I've seen alot of systems over the 7 years I've attended regattas.I've seen the pvc pipe with pipe insulation for a cushion method.I've seen small carts with wheels.I have a 6ft long battleship (41lbs)and I usually find a helper and we each grab an end and set it in.I guess it partically depends on where you will most likely be launching you boat.A ramp launch is different than one straight into deep water.A launch into deep water(like from a dock)shouldnt be too hard with a boat your size.I had back surgery a few months back and they showed my how to lift properly.You should always use proper form when lifting (or launching) back surgery is NOT FUN!!

Tim,
I agree about the back surgery. I will never do it again. As for the launch methods I have a RC Boat Modler Mag that has a entire article devoted to this topic. How many rules, Laws would I break if I copied it and posted it here?

Marine Rail System


It lifts the boat up to three feet above grade, to work on, and then lowers the ship down to the water level.

[edit]
I knew this mignt show up somewhere in the background at Bellevue.
Here are a couple shots of a typical launching rig. This one is threaded rod and wood, but it typical of the style that people build using pvc pipe.
The cross bars, or plastic grate across the bottom cradle the boat till it is down on the water.

This was the boat lift at the Subcommittee subregatta, i think it is actually owned/built by the indianapolis admirals

We've also considered building a mini lock system, so that ships can sail into a "canal" & be raised up to a convenient "workbench" height. Also, a mini "Falkirk Wheel" would be cool. Both need a good supply of water at a higher level, though.

A trebuchet may also be used to launch ships, but not so good for retrieval - if there's anything left to retrieve, that is! ;-)

I don't think any of those lifts would work well with sailboats and their nice long skegs. The side slip launch could probably be modified to launch the boat perpendicular to the shore/dock and work with all boats.

I would think a floating, made of styrofoam, single lock with a battery/solar powered pump would be workable. Steer the ship into the lock. Close the gate, fast fill, pull ship out at 'okay for the back' height and put next ship in, fast drain and out she goes. Probably could be built in a day and for fairly cheap.

Sail boats are easily launched by lowering them into the water buy holding the main mast, don't even have to bend over. I still like the Texas solution.

Thanks
Steve
