Collapsible Cradle

Even the name sounds bad, but I need one.

Here's my problem. I just purchased a 31 ft, 10,200lb sailboat that has no cradle Wing keel, 4" draft. It needs some work, so I am having it shipped to a yard that mandates a cradle for the boats (they use a huge forklift to swap the boats in and out of the work shed). They want to build me a cradle and don't have one to rent.

The marina I want to end up at in the spring is small and has a travel-lift, but no means of moving a cradle around on the property. The winter storage yard becomes the parking/picnic area. That marina insists on jackstands so they can "clear the decks" in the spring and chain the stands up at the woodline on the edge of the marina.

Cut to the chase - it's run by a very stubborn and opinionated woman (who I actually like a great deal) who doesn't like cradles, period. Also, if you don't winter-store with her you tend to find there is no available slip come spring. I'm hoping if I guarantee to have a ctradle appear on the spot when the travel-lift drops the boat and that vanishes again in the spring without her one yard man's involvement I can sway her. I have enough "atta-boys" from a few years back when we were based there that I think I can pull that much of a favor.

So what I need is a break-down cradle that can be disassembled and transported between the work yard and the marina (10 miles) on my 1,000 lb capacity 4 x 8 utility trailer (overhangs allowable with flags) and can be dragged to the woodline in pieces or reassembled as needed on haul-out day.

Anyone have plans or images of such a beast? Thoughts? Ideas?

Sure...

You could probably make the cradle using angle iron and 4"x4"s to create the cradle so that it can be easily disassembled.

You'll probably have to use some pipe in the construction of the cradle to put "boat stand" heads on to support the hulls and keep the boat balanced.

The real problem is keeping the pieces small enough to move and making the cradle light enough for you to move on your utility trailer. Steel angle iron heavy enough to make a cradle you can disassemble is going to be fairly heavy, probably a good deal heavier than a cradle that doesn't come apart.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Sailormann-

Nice link...didn't know about those... and the 1.5 model looks like it'd do the job nicely...

Delirious—

Give them a call and ask how much the cradles are, and whether the #1 would work for your boat or if you really need the #1.5 cradle.

Our club used Jowi cradles for many years. Most were Model 1s. It takes at least 4 people to lift one onto a trailer - 6 is better. While removing the stands will help a bit, the base is one large heavy welded piece. Model 1 cradles were about $500 plus shipping when we bought them over 20 years ago. Probably more like $1000 today.

Marine Cradle shop in Marham, Ontario builds folding steel cradles.

Mine measures 11 feet x 5 feet x 11 inches when folded. Problem is that my boat weights 3800lbs, 8.5 beam, 27.5 LOA. The cradle weghs 440 lbs

Your boat is considerably larger and heavier

Look at page 7 of http://www.grampianowners.com/G34/g34_manual.pdf for a timber cradle for a 34' 12,000 boat.

The drawing is a little hard to make out, but the cradle is 8' wide and you can estimate the other dimensions from that. The uprights look like 4x4s. Check Home Depot for 4x6 and 6x6 landscape timbers for the bigger parts, or nail 2x6s/2x8s together. Of course the "pad" height will have to be adjusted for your boat.

Bolt the major parts together. If you can't get carriage bolts long enough, use threaded rod. 1/2" diameter with washers will be big enough.

If you use some ramps and the mainsheet tackle off your boat, it shouldn't be too difficult to drag the cradle onto your trailer.

Good luck,

Tim

We've used a cradle that consisted of 4 posts (4x4 square tube) c/w adjustable pads connected with scaffold type scissor braces. Easily fits into the back of a small truck or van when collapsed. I believe a company in the Okanogan area of BC produced them.. Worked great. A long ways from you but I could try to find out the company name if you like.

All for nought.

I called the marina and talked with the only yard-man. He made a good point that he's often lifting and setting boats alone and lacks the equipment to drag even parts of collapsing or break-down cradles and, as often as not, the owners don't show up for their actual pull date/time. Have to drop the mast to use the full-box lift there anyway so the cradles don't offer that advantage.

The good news is that I went back to the yard that will be worknig on the boat over the winter and they've agreed to arrange a "loaner" that I can lease for the winter.

Thanks all. That Lowi looks like a good cradle.
