Thanks for the responses and the useful info, it's always good to see how other people approach the problems around moving 60ft of mahogany and oak!

I wouldn't got that far, still learning Smile

So far we have saved the cost of 3 cranes, the cradle worked out at roughly the cost of 2 cranes, so its already paid for itself. We used reclaimed steel and it is substantial, I'll do some photos over the weekend, but the main part is 12" box section, where we have a pair of "out riggers" that can be slid out for when we crane her back in so they clear the hull.  For road transport they tuck in as she is a little over 14' wide at the chine, but 17'6" at the deck and we didn't want 3' of steel jutting out from her during transport.

The other advantage of the cradle we had made is that it was built from the original shipping cradle plans from WW2, those plans have the water line marked on them so when the chine packers were welded to the frame they were done at the correct height so that when the cradle is level that is how she will sit in the water.  This will make fit out a lot easier as we will know what level to use.

I have the centre of mass plans so as we refit we will be mindful to try and make sure the weight distribution is the same, she should be lighter in the water than she was, as there won't be flak jackets etc on her, less fuel, lighter engines etc, but we'll be very careful to make sure the balance is the same.

Cheers
- Paul

Hi Paul,

Ah, there you are re someone who knows what they are talking about! indeed, as you say, the initial investment in a good steel cradle is high, but then the saving as you say, on craning...., all the best,

Hi Caprella,

No crane needed, because she sits on a steel frame the low loader jacks itself up, using its own air suspension, we then put packing towers made for sleepers cut into quarters, the low loader then deflates its air bags and lowers her onto the towers, it the continues until it is clear of the frame and just pulls out.  There is a considerable investment in the frame, in our case it weighs over 3t, however the cost is more than offset by the savings in cranes.

Once the low loader has gone we used bottle jacks to take her down, a couple of inches at a time, slowly removing a sleeper, only took about an hour.

Cheers
- Paul

Hi Caprella,

Many thanks for your post there, yes....good to ask re jacks etc, sounds like it may be a bit of a strain on the hull...BUT you need an expert opinion, which is certainly not mine! best of luck,

Johnk
