2014-05-20 11:05:06 - Geneva Lake Sprint race and the AC72.
The Bol D'or is a short race in the Lake Geneva or also named Lac Lemand. The length of this race doesn’t make justice to the difficulty’s it has, namely the wind conditions the sailors will find during the course. Tactics and fine hand on helm is a must to succeed here.
This is the second race we propose to be sailed with the new AC72 SOL boat.

I and Jan hope that all SOLers enjoy it.

Might the new boat be ready for a Sprint race on Lake Geneva in 3Q2014 or will the possibly excessive performance loss for a tack or gybe not yet be addressed?

2014-05-22 10:29:35 - Re: Geneva Lake Sprint race and the AC72.
The proposal for the AC72 includes two innovations:
1/ a radically different performance loss model.
2/ a radical loss of boat speed above 28kn windspeed down to 0kn when the wind gets up to 40kn.
However....
the AC72 will fly just as well without these and there is no reason to simply:
1/ run with the existing performance loss model (there just won't be much tacking or gybing going on and quite a bit of pinching and soaking deep to clear a mark or obstacle, like in the KergCanCan only worse).
2/ assume all the boatspeed curves above 26kn are the same as at 26kn; you just can't go any faster.
If we did that, we could be out on Lac Leman or off Cascais as soon as there is a gap in the calender?

SSANZ Round North Island Race 2026 - Leg 3

Leg Three of our Round North Island Series, in partnership with SSANZ, keeps the pressure on! From Cook Strait, the fleet turns north for a 187 nautical mile passage up the east coast to Napier. It may look like a quick overnighter, but shifting coastal winds and the ever-lively Cook Strait demand sharp focus. In our responsive Sun Fast 3600s, a proven short-handed racer and powerful downwind performer, tactical decisions and precise timing will make all the difference!

Welcome all to the South China Sea and a virtual chase in Cookson 50’s of the Rolex South China Sea fleet, racing 650nm – as the local red-footed booby flies – from Hong Kong to Subic Bay on the southern tip of The Philippines’ Luzon Island. Chances are it will be a fast downwind ride, so see how you can keep up with the real-life fleet which we hope to be able to follow on our monitors.

Iceland to the Falklands 2026

Welcome to an all-new route, the first of three Round the 'Old World' of Europe, Africa, Australia and Asia. To give each leg of the ROW a bit of length we'll try to hug the coasts as little as possible, so starting in Iceland our first leg of the series, which will also be the final leg of our Quarter 1 Ocean Championships takes us 7200nm to the Falklands, the full length of the Atlantic end to end. To make sure we'll get it done within the month we'll be sailing our Maxi Trimaran.
