Read my account of how the CLOUD TEN, design was developed

 

In July2009 Cornwall Council engaged consultants to “rubbish” my proposals. That report together with my marked up comments is available at :CLICK HERE (word document)

The consultants' report is poorly researched and consequently their conclusions are not valid, in particular their statement that CLOUD TEN would be limited by regulations to calm seas only is not supported by any evidence. On the other hand I have discussed the design with the UK regulators who see no problem in replicating in the UK the ship’s existing permit to operate on international voyages up to 150 miles from shore in sea conditions up to a significant wave height of 4 metres. In other words the ship is more than capable of operation on the Isles of Scilly Route throughout the summer season.This is partly due to the excellent sea keeping characteristics of the SWATH design and partly  due to the “flood down” evacuation procedure, unique to the SWATH OCEAN design, see video as above, which in an emergency enables passengers to be evacuated directly into the life rafts. (See extract from the Stability Book which fully explains the procedure).

 

Elementary reasearch on their part would have have established that they were using defective wave data. A subsequent report by Bacon and Carter  showed that the  data used by the Consultants overstated the wave heights on the Isles of Scilly route by up to 20%. see page 8 of Bacon and Carter. or the full report published by Southampton University Library This further undermines the validity of the County Council consultant's report.

 

The consultants also make very silly comments about the US Coastguard and the "high speed code". They did not even bother to find out that CLOUDTEN conforms to the International High Speed Code, if she didn't she would not be allowed to put to sea. See IEEE article about how the sea trials data was collected and recorded

 

The same consultants were engaged by Cornwall Council to rubbish my proposal for continuing with a two ship service to the islands. I found so many gross errors in their figures that their report was eventually and quietly withdrawn from publication! In other words they are not very good as consultants and their conclusions have been proved to be suspect and unreliable.

 

My reports are based on my many years of practical experience of managing and operating the Isles of Scily sea route and my extensive research into methods and systems used by operators on similar routes in other parts of the world, backed up by personal visits and discussions with them on site.

 

Note, I visited the ship again in January 2010 and the information I brought back, discussions with the chief engineer and examination of the stability book and voyage log books further endorse her suitability for the Penzance / Isles of Scilly route.
