BOAT'S PERFORMANCE #1

BOAT'S PERFORMANCE #1

Bruno Belmont, our sailing expert, shares his expertise on catamarans and their performance in an interview with Thibaut de Montvalon, Director of the Excess brand.

In this video, you can find out about the different hull shapes, the elements that slow a boat down, displacement calculations and the prismatic coefficient...

Bruno shares with us: "Looking at hull shapes, we've seen, and even proved, that asymmetrical hull shapes perform better than symmetrical ones. For the Excess 14 and the next generation of Excess, we've decided to increase the draught and switch to asymmetric hulls.

That's all we need to tell you, and we'll leave you to dive into his fascinating explanations!

Thank you Graham!
One of the aspect I love the most in our job is having the opportunity to learn from, and to interact with, experts such as Bruno. I see the Excess Lab as an opportunity for us to share this privilege with a larger audience of passionate sailors. I am glad you enjoyed this discussion!

I think the conversational style of the interview to discuss performance, design, technical issues which can become complex was a great approach well done Thibaut Bruno

Merci Bruno and Thibaut for this interview. As prospective Excess owners the technical and engineering details are very interesting . A question please - I understand the Excess 11 and 14 can dry out on their keels - will all future Excess models also be able to do this with the narrower and deeper keels Bruno mentioned ?
We are looking forward to a charter in Tahiti in May on the Excess 11 and hope to experience the cat in higher winds and sea states than our lovely but calm outing in Cannes last year.

Dear Roy and Vicki, yes we will pay attention that, despite narrower keels, the Excess catamarans can dry out on their keels. Hope you have a great time in Tahiti on the Excess 11: no doubt that you chose the best landscape! Best thoughts, Bruno
