Dibley designed International 1m (IOM)
Dibley designed Marblehead’s (RM)
We started designing International One Metres (IOM) and Marbleheads in 2008 and for a few years from 2011 we had a separate company building them in production runs.


They were marketed as the DM range and had dominated the New Zealand fleets since they first came on the scene.

Production stopped in 2017 as the builders were going down new career paths.



The yachts sailing include the following designs which have different characteristics depending on the conditions and wind strengths:
DM1,2 & 3-IOM’s; and DM1,2,3,4,5 Marbleheads.

The DM-Marbleheads won the 2009, 2010 and 2011 NZ National Championships and many other regattas since they first came out.

The DM-IOMs have been NZ National Champions as well as podium finishers over many years and are still active and doing well globally with yachts in the USA, Australia, Asia and Europe.

They are proven winners, easy to handle, and beautiful to watch under sail.
