Nacra 17: Lange & Carranza training in Brazil for the South Americans

Santi Lange & Ceci Carranza had an impressive debut after a few months together in the new Olympic Nacra 17 Class, peaking at Santander Worlds where they ended second only behind the current indisputable Nr1 crew and the 2014 CSN Sailors of the Year Billy  Besson & Marie Riou.

The hardest working sailor in this team is definitely Cecilia, as they have defined she need to lose weight coming from her Laser sailing days.

So beyond the intense sailing sessions she is also on a full training program to adapt her body for the demanding task of crewing a powerful and lively cat like the Nacra 17.

Lange is 53, and pretty exited with this new campaign as he is fondly to comment, after his 2000-2008 campaigns having the opportunity to follow more closely his current road to Rio is a real privilege, as many of us here started sailing & racing cats on his Tornado Olympic rides.

Speaking about the Rio road, this time the Arg teams are being able to sail in the Olympic course quite often, it is a long car drive from Buenos Aires though, like 2600kms , but the chance to take their own boat and train in the Brazilian perfect climate and beaches compensate any long driving trip.

Next N17 events will be the South Americans to be held in Rio on December 9-11. NOR available here

Pictures of the building process! I want pictures!

Especially of the mould building for the foils and the main foil building :-)
Laminating schedules for foils, daggerboard case, beam reinforcement..

So many have been talking about CNC and big budgets. It is fantastic to see the garage boatbuilder movement strike back with a plywood creation from the dark carport.

Hi, thanks for your interest in Stealth Aus. the concept I developed with my son Brad who designed the hulls. I did not have a big budget so I built the 15' 6" hulls out of ply in my carport. I Glued 3 broken sections of A class carbon mast together and rigged it with a 2nd hand cut down A class main to end up with a boat costing $ 4,500.
After watching C class foiling Brad and I decided to design and retro fit foils to the Stealth. To construct the moulds we had 8 plugs (4 for each foil) made up using a router machine at RMIT, and then took moulds of the pugs. The 1st set foils I laid up had 10 layers of 200 gram carbon and a expanding foam core, they weren't up to the stresses and broke under the keel. The 2nd foils of consisted of 15 layers of C F with end grain cedar core They are still good a bit heavy (5 kg) each.
The epoxy glue for the foils was sponsored and supplied by Marine Timbers and the rest of the materials for moulds and foils cost around $ 2,500.
It has not been an easy development process due to the fact that Stealth was not built for foiling.. Breakages include ! set of foils, 4 rudder blades, 5 rudder boxes, had to reinforce the main bulkheads,

my thanks to Robbee who tirelessly developed the tuning of Stealth Aus

happy to share do you want pictures by email or face book

Rolf Nilsen said...

By mail would be fantastic (no facebook - too much of a time thief)


We are currently building foils for our strip plank F-16 project. I have strip plank hull panels for two additional boats in storage which I have not comitted to any projects yet besides another F-16. Last set of hull panels could go to an experimental boat..

hi barry
thanks for the inspiration and showing it is possible to make a garage foiler.
I would also love to see pictures, please send to palmerjeremy
what do you reckon would be the min length for a double handed version ?

Michael Airey said...

I used to build Unicorn A class cats out of ply. The hulls were light enough, but the ali beams and mast were so heavy. Ply hulls with carbon beams mast and foils will be great. I don't think the hulls have to be asymmetrical either!

poul said...

Do you have plans of the hulls please?
I would like the build photos too,

Barry Marmion said...

I can arrange some plans for

Barry Marmion said...

hi mike, the last A class I built of plywood had allie mast and beams weighed 72 kls

Michael Airey said...

yes -heavy. We cold molded some, first out of mahogany and then out of cedar. The cedar ones would have been good if faired and covered with carbon cloth!

Waving not drowning said...

I think Barry was suggesting 72kgs with alloy beams, mast and fully rigged was light. And it is/was given current min weight is 75kgs

My son Brad Has drawn up plans of stealth version two let me know if you are interested

Chris Ross said...

Are the plans for Stealth Mark 2 available?
