getting boat out of the water- lateral thinking required

I need some help, our slip is on a river and cantilevers out over the water so at best it is 3" above the water level at worst 6".

this makes it quite a PITA to get the boats out of the water. We have a manual winch at the top of the slip but you still have to lift the front of the boat 9"-12" out of the water vertically before the bows are on the back of the trailer.

What i am trying to work out is a way of lifting the boats the first bit onto the trailer that will not get in the way of the boat later on...

Whats the cantilever part of the ramp made of. If its wood can it be altered to follow the same angle as the rest of the ramp.

You could do with a break back trailer.

You want to either convert your trailer to break back or buy a break back trailer!

^^ this.
or the back break trailer.
or a davit on the shore to lift the bow of the boat until the trailer winch can pull it forward onto the trailer.

Thanks, unfortunately we have 5+ trailers and can't replace them all with breakback ones, the cantilever bit is made from wooden sleepers.
Wondering if some sort of a frame affair might be the way forward.

Aquadock then, drive the boat onto it then winch it onto the trailer - only problem is you need somewhere to keep it.

Buy an engine gantry on ebay - the A frame type not the crane type, wide enough for a trailer to go through - I got mine for £200 and it lifts 2tonnes

tie the trailer off to a strongpoint so it cant run away and then run the jockey wheel up a car ramp. you could get a tame welder to put high sides on the ramp. this will effectively lower the back end of the trailer



i'm off to look for a safe mover be back soon

The best option is break back trailers however

Getting there.
Chock the trailer wheels, run the bowline from your pulley through an eye over the top of the trailer pulley and onto the bow.
simply cranking the boat onto the trailer will allow the boat to slide onto the trailer and balance itself once on. A bit of physical damping and care to be taken at the tipping point though!!!!

if the above suggestions don't work

http://www.globalindustrial.com/g/ma...-steel-handles


take the concept of this tool and fab something up

i to have a small V cradle at the end of the short lever. With a bit of effort that should easily raise the front of the boat enough to make the trailer

As others have said chock wheels and winch on from trailer winch to bow d ring. If you are worried about the chocking of the wheels then run a tether from the trailer axle (the pivot point) to a good anchor point.
You will still need a line or something to control the trailer hitch though.

a long pole on the jockey wheel would do the same job

Hows about an A frame on the back half of the trailer, lift the boat nose on with a winch. Possibly very simple to achieve.

I have lifted boats with a 2 foot drop out of a canal or when its a spring tide and its caused a drop off at the end of the slipway using this method
Just make up a bridle fixed to the transom about the same length as the hull
Run it under the boat with a shorter piece of rope joining the bridle together so that the bridle ropes don't get separated too much by each side of the keel ,
( the shorter the cross rope the higher the boat will be lifted )
Using the trailer winch it can then be lifted & winched right onto the trailer in one go ,
Just make sure that the short rope or a webbing strop joining the bridle together is strong as well as the transom fixings as it is that which takes the main load of the lift .
& that you have a roller right at the end of the trailer .

thanks guys, i will give a few of those a go and see if they make it any easier. The strops under the boat is an interesting one, not sure how easy it would be to do regularly but will give it a go on wednesday.
