Robinson 16 Dibley Marine

Robinson 16

Earlier this year we had the pleasure of working with repeat client, John Robinson, on a new multihull project. 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 16.

The Robinson 16 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.

There is talk of a stage two where foils are looked at for the rudder and boards, but that will develop over time.


LOA 5.000 m 16’ - 5”
LWL 4.890 m 16’ - 1/2”
Beam (Sailing) 3.000 m 19’ - 10”
Beam (Trailering) 1.096 m 3' - 7"
Displacement (Sailing) 155 kg 342 lbs
Displacement (Lightship) 75 kg 165 lbs
Sail Area 13.24 sq.m 142.5 sq.ft
Disp/L Ratio 37
SA/disp Ratio 46.6

The first hull is currently being 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 will be built by Alex Valling, of C-Tech, who runs his very successful factory out of Auckland. (

Sails will be by
Doyles NZ, and all deck gear is supplied by Harken NZ.

This will be a fun project and we look forward to plenty of sea trials during the 2014/2015 Southern Hemisphere summer.
