History of IOM RC Yachts

Created in 1988 by Jan Dejmo and Graham Bantock, the IOM class rules were written to enable boats to be built from scratch or kit by non-expert builders and inexpensively by a commercial builder without disadvantage to either group.

Hulls must be constructed of either wood as this beautiful example

or glass re-inforced composite with carbon fibre being allowed in the construction of the fin and rudder. 


Spars shall be of alloy or timber and the sails are to 'One Design' sizes, with the number of rigs is limited to three.

This makes  the class very popular for amateur builders and many designers have plans for competitive boats. There are a number of Builders here in UK and overseas,  who can supply plans for home completion, hulls and rigs or complete boats.


A limit of three different rig sizes allows sailing in most conditions from a lazy summer day to winds gusting over in excess of 30kts!

These boats, which handle beautifully, are fast, responsive and quite addictive. Once you have experienced  sailing one, there is no going back.
