Getting interesting on Ambra...

I thought that she would be double diagonal on the sides and triple on the bottom, but interested to find out.

Later boats had raised chine in forward sections, but I do not think that it affects the overall lengths.

Solid bearers could have been for the installation of the Gas turbines when she was 'Southerner'.

I am interested in seeing the plan and finding out what other information 'pushback' has.  

The designs were all developed based on moulded lines, which were then lofted up. The frames were built in jigs taken from the loft floor and built up into the boats skeleton, with planking added onto that.

This allowed for fast and accurate building of subassembly component at any location and less time on the assembly line. 

The earlier boats were generally built as first of class and then the finished dimensions lifted to make jigs for the rest of the series.

Regarding the length, then an additional 3" could easily be taken up by the moulded line at the stem and transom, but may also include any rake of the transom in relation to the baseline, however I have not compared the lines of these boats with a real one. 

Best regards AndyS

I would think that it is difficult to compare 506 with the standard boat as she was "interfered with" when the Gas Turbines were fitted which would have meant a whole host of mods in her stern/engineroom area.

I spend quite a few days going over the engine room in the Ambra, I have no idea what mods were done for the turbines but I cannot find anything under the engines that was not there originally, also very few if any modifications. Engine beds and structure as per original under the floors. The only possible evidence of turbines I can see are the two 18inch extractor fans. Between the engine room and the aft steering gear compartment.

The only changes to the hull I can find are the removal of the two bulkheads and the upper works.

Id be interested if anyone has any idea of what mods were done to fit the turbines.

I have located the boatyard that worked on the boat once she was sold to Malta and before captain Morgan bought her. They may know more. I will ask when I get the time

506's transom must have been replaced unless they just planked over the jet pipe exhaust holes giving  the boat a bit of extra length.

Yes the transom has been quite heavily planked over. However the bulkhead between the engine room and the transom (e.g. last compartment that contains the steering gear) is still in place. Or it has been replaced.

There is a couple of bulkheads that look quite flimsy replacements. That being one of them.

.I think the only original full strength bulkhead is the fore engine room .That now has a dam door cut in it.
