For those that are following HSL2552 things have been a little quiet recently due to a number of challenges, we have overcome these challenges and as a result she was re positioned onsite to somewhere where we have better access.

I have started to update the blog at http://hsl2552.blogspot.com/ after a 6 month gap, where we have done no work on her as we knew should would have to move.

There is a shortish movie of her move on the blog and also here https://www.youtube.com/watch?v=RQ1IQbTiRUo

We are in the process of arranging to take over a 40' container that is onsite, this will become our workshop over the next month or two as I kit it out.  I have sourced a supplier for the Resorcinol glue that we will be using to create the laminated frames and deck beams, having read one of the boat making books I purchased a while ago we will be remaking the frame jig, the mark 2 version will allow us to make 5 frames at a time and the deck jig we will be making will allow us to make 5 at a time, vastly increasing our efficiency (not sure the missus sees it that way!).

---------- Some photos of the move ----------

Loaded, ready to move..........

How is this for close?

Hi, I am moving a 60ft Naval Pinnace (Caprella) this summer so was very interested to see your post and the video, thanks for sharing that. Was HSL2552 craned off the trailer? The reason I ask is that we are considering using jacks to lift her off, as crane access for us is a problem. At the moment we have Caprella sitting on an H beam cradle with acro jacks welded to the frame providing support along the chine rail.

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,

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 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,

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
