Botin Carkeek - TP52 2010 modifications

I doubt there is anyone better suited to talk about the modifications on the TP52 yachts for 2010 than Marcelino Botín, designer of Quantum Racing (Medcup & World Champion in 2008 and Medcup & World runner up in 2009) and Emirates Team NZ (Medcup chamion in 2009). So, here's what Botín had to say about his two designs:

The main modifications to both our TP52s have been done mainly to meet the new 2010 rule changes.

Emirates Team NZ did clever improvements all over the boat to further optimize every system, under the supervision of Richard Meacham. We have reviewed the new larger sailplan with our CFD/VPP technology at different sailing conditions, and designed a new rudder to match the predicted changes to overall balance. Also a heavier bulb and a new bowsprit were fitted, under the guidance of principal structural engineer Giovanni Belgrano. Wind Tunnel sessions were carried out in Auckland as well, to come up with a new gennaker concept.

Quantum Racing received a major upgrade, as we have designed a new deck shape and layout. This was done in close collaboration with the team, which had several new ideas to keep improving. The boat is being modified at Longitud 0 yard in Castellon, were it was originally built. A new bulb and bowsprit have also been designed for them. Our CFD engineer Alberto Porto has worked closely with Quantum’s head designer Dave Armitage, and a full aerodynamic optimization programme has been carried out on the new 2010 sailplan. This work has been going on since early 2008 with great success.
