Any Mechanical Engineers out there? Has anyone developed a pully system for hanging the yak from the roof of the carport? And, if so, would be willing to supply the details. I want to lift the yak up out of the way and don't particulary wish to pay an outrageous price for something commercial. Would try to figure it out myself; however, is someone has already done it - Why reinvent the wheel? Ok, so I'm cheap!

G'day Duncan - I do exactly that - I have a pulley system that lifts the yak on and off the car and then it hangs under a large beam out of the way - it works well for me although I'm sure I could improve on it. PM me if you want to catch up some time to have a look. The very basics of it are an awning pulley, some rope and seat belt webbing. cheers

Now I have two yaks I've been thinking about a similar set up myself. I would appreciate any plans, descriptions or diagrams on this also.

Any chance of sending me the PM also. The roof is the only place that I have to store the yak, was going to work on it when I got it but a heads up look would be good.

Hi Dodge/Fisher

I will also be suspending my Yak from the roof and any ideas from you guys would be greatly appreciated

I am developing a "bunk" system - to eventually store 4 kayaks.

This system has worked well for me. The pulleys are sailing fittings which, together with the rope was purchased from Bias Boating Warehouse. The slings under the yak are 50mm webbing with buckles purchased from a camping store.

The buckles enable you to release the yak without having to pull the tackles right out.

The more purchases you put in the tackle the better as they give you more control and the friction stops the whole lot crashing to the ground if you let go of the rope.

Email me if you need more info.

Duncan,
I'm no mechanical engineer but I have a similar system to the one here except I have made some slings to hang the yaks on there sides (perception says this is the best way to store their yaks as the side walls are the strongest part of the whole show). You would not have a problem with a hobie I dare say though!!! they look plenty strong!!! :lol:
this is not a problem because I have fairly high ceilings in the garage. the slings I made from old seat belt material that I scavanged from a wreckers but you can get the same material from bunnings. All other materials are readily available fronm Bunnings.

It would seem that I don't have photo's anymore so I'll take some tomorrow and post them on - hope it helps.
Happy paddling.
Phil.

Duncan here are the pics of my system. Overall I used 4 lengths of seat belt material, half a dozen carrabeena's, 8mm rope, Eye screws (but these will be replaced with eye bolts shortly) and the tie off points. as you can see Iv'e well and truly over engineered but that's the way I like it

and both yaks are out of my way and ready to drop onto trailer - they won't fit out the door on top of my Pajero :?
Hope it gives you some ideas mate. Oh another thing Perception recommend not storing by handles - it voids your warranty I was told but you could always hoist it up by them and then have some more straps to support once there if you like.

Jacktheyak has similar to what I am building with minor variations

I only have a single pulley above the keel of the yak and rope to another pulley at the carport edge, then down to a cleat.

There are 2 lift points..above the point just in front the swing footwell..and another behind the cockpit and in front of the rear 10" hatch.

Because of crushing concerns to the hull I lift by a padded timber slat which wont bend [as on roof rack], from each end of the slat a rope curves around the hull to a single point above the keel, where the lift rope attaches.

My biggest headache was the carport itself, which has no cross members, and only alum sheets; I am overcoming this by having two timber arches under the roof at the points required for the Swings lifting points.

The house has an upright attached to the wall, then the cross timber under the roof, to a free standing leg on the lower side of the carport.

Each kayak has a pulley above its keel to lift up and each has its own second pulley before the rope goes down to the cleat.

Because of the Swing measurements set the arch spacing, the front lift slat is above the front hatch on cockpit gunwales on the Espri, and the rear slat is half way down the rear well

The idea is proven by a mate who lifts a tinny with outboard the same way in a shed, and dinghies to davits only have a single lift pulley above the centreline

Thanks to everyone for their ideas - really apprciated. I will take on board what all have said and see if I can't put up a good workable system. Was hoping to use a couple of double pullies and come up with an efficiency of about 4:1 and use a single line to do the pull up with. Everything would have to be just right to achieve a level lift. We shall see what happens.

Good luck with it Duncan.

I've just had our carport finished and want to set up a pulley system as well. I can figure it out using two ropes, but not sure how to go abut using just one? Any idea's would be much appreciated.

Hi Duncan

Have a look at photos at: http://www.johnluck.net/index_canoe.html

If its what you want, it only takes 2 x Eye Bolts (Dyna Bolts) 4 x $3.00 pullys and some rope.

Hey Ferret: Thanks for that link - real interesting, especially the cheap trolly. Am planning on doing something similar but using a couple of extra pullys to get a greater mechanical advantage.
