In this video, we see an AM38 in evolution. The AM38 are the largest training boats authorized for the Cup which takes place on the AC75. These boats, called "mules", make it possible to implement complex flight techniques and train crews.
The first AC75s - twice as large as the experimental AM38s - are expected to hit the water in July 2019. There is no doubt that the regattas promise to be spectacular.
These images are already stunning. Despite the surreal speeds, the AM38 seems very manoeuvrable, when it comes to stability it is all relative to the phenomenal speeds.
Flying monohulls without a keel
What seemed impossible just a few months ago is now becoming a reality. In beautiful HD sequences, we see this 38-foot monohull in constant flight. Remarkably, it maintains its flight during gybes and tack changes.
Slow desalination
Another sequence of the video shows the desalination of the AM38 stealthily. The reason is not quite clear and the capsizing occurs almost in slow motion. Contrary to what was announced during the presentation of the AC75, the AM38 is not self-righting, it stays on its side without turning around.
Some selected pieces
As there are long interviews in English with the crew, we have extracted some selected songs:
Dean Barker, helmsman (6th America's Cup)
"It's a very interesting boat, the dynamics are very different from catamarans. It's a big challenge. It is a challenge to learn the behaviour of this new boat. The speeds are quite phenomenal. I think with the AC75, we're going to see some exciting actions."
The same Dean Barker referring to desalting, "Sometimes you learn the hard way."
Nick Dana, partner
"It exceeded all our expectations."
"This is the first time I've flown on a boat bigger than a foil Moth. For me, it is an unreal experience - softer than the one I am used to. A much smoother and faster ride. It's really cool what you can do with 10 knots of wind on still water."
And on closer inspection
- It will not be easy to keep the boat flat during transfers and gybes. However, the choreography already seems to be up to speed, as the foils move almost imperceptibly.
- It is surprising to see the impressive hollow of the sails for such a fast sailboat. The Mainsail (and solent) trimmer continuously adjusts the mainsail trolley to maintain a constant trim.
- To optimize aerodynamics, the crew is confined to deck cuts with manoeuvres and winches within reach.
