Maverick: a few neat features
Maverick's rudder is a single composite blade and stock which is mounted in a water tight carbon tube that sits behind a water tight bulkhead. This tube houses large bearings at top and bottom which are ideal for transferring loads to the hull structure. Any failure is unlikely to result in water ingress.
We can access the rudder blade and bearings from the deck and if necessary make repairs or replace the blade whilst at sea. We carry a spare rudder just incase.
Our canting keel systems were designed and manufactured by Cariboni. The keel fin is a single forged piece of milled steel. The keel cants 35 degrees in 45 seconds driven by a hydraulic ram. In the event that there are issues with the primary hydraulic ram we run a secondary hydraulic system to control and centre the keel.
We have mounted our impeller log on the keel bulb - as far underwater and away from cavitation as physically possible. This way even as the boat lifts and jumps through waves we hope to capture accurate information on boat speed. The impeller is linked to our NKE systems by a cable that runs inside a 10mm diameter +3m long hole that was drilled down the centre of the keel fin.
We decided not to power the boat systems from the engine or a generator. On longer offshore races we save on the weight of diesel and do a little bit for the environment. All of our instruments, the keel, water maker and hydraulics run off our lithium ion battery packs. Whilst at sea we charge our batteries using a Watt & Sea hydro-generator.
We use manpower to drive the Harken winches and the reserve hydraulic systems.
Rig & sails
Maverick's rig and sails were worked up in partnership by Axxon, Future Fibres and Doyle Sails NZ.
The Axxon mast is deck mounted with a 2 spreader cathedral design. All standing rigging is Future Fibres PBO and lashed at the mast to minimise weight aloft and to reduce wear. Through Axxon's design efforts the rig is very light and achieves the lowest possible centre of gravity. Minimising the weight aloft and keeping what weight there is as close as possible to the waterline multiplies into weight savings on the whole boat.
The boat was built around the sail plan developed by Doyle Sails NZ. The bowsprit bobstay is engineered to carry a load of over 30 tons, allowing Maverick to fly the mast head and fractional code sails usually seen on larger offshore race boats. The Doyle sails are STRATIS GPx for beating or reaching and Contender Superkote for running.
Despite the high loads there isn't a piece of rope on the boat which is more than 10mm in diameter.
