Robinson 5000
Repeat client, John Robinson, commissioned us to design a new beach tri for his personal use.
John lives on a cliff edge, overlooking Stanmore Bay in the Whangaparaoa Peninsula, just north of Auckland.
This Bay has one of the best beaches around Auckland and John wanted to have a fast, fun, easily rigged trimaran that he could have fun with over the summer.
And just as important, he wanted the outer hulls (Ama’s) to hinge back towards the mainhull (Vaka) so he can trailer his Tri back home to the cliff top.
The result is the Robinson 5000.
The Robinson 5000 is easily rigged and sailed by one person. All controls are within reach of the helmsman and the rudders effortlessly flip up when coming into the beach.
The Ama’s have a length-to-beam ratio of 14:1 and enough buoyancy to lift the main hull out of the water, but not so much that drag and performance become an issue.
Built by professional builder Richard Edlin, who runs a yard out of his property in Matakohe, Northland. His property lies on the edge of the Kaipara Harbour, and is as pretty a place as can be found on the west coast of North Island.
The carbon fibre spar and other carbon fittings were built by Alex Valling, of C-Tech, who runs his very successful factory out of Auckland.
Sails are by Doyles NZ, and all deck gear is supplied by Harken NZ.
