Mainsail headboard car designed for 60’ Bonduelle
Materials: Titanium and aluminium
Working load: 5T (11,000 lbs)
Weight 1050g (2.31 lbs)

Bonduelle

Racing Yacht “Bonduelle”: Jean Le Cam (Skipper) was looking to optimise the mainsail track on Bonduelle. No existing system on the market was satisfactory to him. Working closely with Jean Le Cam, Karver designed a 1 kg (2.2lbs) headboard that minimizes torque on the track and integrates a 3:1 purchase.

Furler drum KF 12 installed on the 60’open Catamaran Mediatis Région Aquitaine
Materials: carbon, titnium, aluminium
Working load: 12T (26,400 lbs)
Weight 3358g (7.39 lbs)

Médiatis Région Aquitaine

Racing Yacht “Mediatis Région Aquitaine”: Yves Parlier (Skipper & Inventor) works with Karver to change innovative ideas into complete systems and solutions. Utilizing a 3-point lashing technique through the eye of a KF12 Furler drum a dramatic reduction in weight was achieved without compromising integrity.

Multi jib-sheet block designed for 60’Open multihull Gitana XI
Materials:
Aluminium alloy
Working load 5T (11,000 lbs)
Weight 870g (1.91 lbs)

Gitana XI

Racing Yacht “Gitana XI”: Fred Le Peutrec (Skipper) wanted to have his 3 foresail sheets run through a single block. Karver designed the K5C1 block capable of accepting 3 large diameter sheets and attached the block with a simple 3-point lashing. This block conceived and developed with Fred Le Peutrec by simply exchanging some ideas was delivered within 3 weeks.

Runner block
Materials: Carbon/ titanium
Working load 12T (26,500 lbs)
Weight 1000g (2.2 lbs)

ABN AMRO

Ben Wright, technical director of the project has asked us to develop high load low friction blocks for their boats. The Volvo Ocean race is the best real life test for our custom blocks and has enabled us to develop and validate a new technology to ensure minimum friction and weight on vital blocks (runners, main sheet) where safety can not be compromise.
