i know - it cannot do the VOR any more... record chasing is good, but it does not answer my questions:
'But that would mean massive changes to the hull...
How can you bring the CG further aft without moving the heaviest parts - keel and mast?'
the keel alone holds around 45% of the weight - you know that moving the fixture of a canting keel means MASSIVE reconstruction of the support structure?
why in the world should anybody do that?
it is probably cheaper - and safer in terms of structural integrity - to build a new hull from scratch...
There is the idea that Carbon boats are not easily repaired or modified and that is partially true on the sense that needs more equipment, the same it was used to do the boat in first place but given that pretty much is possible. There are racing boats that have been considerably lengthened, some Australian big ones and the the same with some ORMA boats (trimarans) that were transformed in new bigger trimarans cannibalizing the smaller boats.
It can be made but it is hugely expensive so in the end probably you are right and they did not modify substantially the keel placement and as Robelz suggest probably they just brought the bulb aft and only that will make some difference. We are talking here about small differences. I don't believe that the boat was wrongly designed. In its time it w a winner and the boat had beaten then the monohul 24 hours record. We are talking about very small modifications to better the boat, not big changes.
Yes, the boat cannot race the VOR anymore, since it is a mono class now but could have raced the last edition. It didn't race it because it was not competitive anymore regarding the new VOR generation. Nobody would be wasting a fortune on a new boat if an old one with some modifications could win the race.
Robelz, what makes a boat good for chasing records, I mean long distance ocean records, is not different than what makes him good for racing the VOR. The difference is that while beating records the crew is choosing the weather for a perfect run and the boat does it alone, on the VOR they don't chose the weather and are on direct competition with other boats.
