open 60 out riggers
The outriggers are there because the masts (shaped like a wing) rotate like a swivel, they have a scale to indicate mast angle. Some masts now allow up to 90º rotation. The outriggers rotate with the mast.
The outriggers are telescopic and allow the mast to rake forward and aft , so she is allways optimized for sail enhancing performance on all points of sail.
These are way out of our reach from us normal mortals, and are very complex. By the way the boat is a Transat 60, and are normally sailed solo in record breaking attempts.
Its a dream machine that also suffers severe structural failures due to the conditions they are sailed. Normally the masts break, because they are really sailed hard.
These boats altough slower than the "sister" trimarans, require a lot more dosage of sailing ability and are also harder to sail.
