International One Metre
Irish National Class Association

Does this mean all One metre boats are the same ?

No these rules allow boat designers to experiment and use their skills and creativity to design boats which still comply to the rules and this allows for a good variety of boat designs that can be found racing together and competitively.

Some boats like the TS2 (Australian design) are very wide and called skiff design. Some others are rather narrow and deep like the SC4 (also Australian) (Ok there are also boats designed by others than Australian like the Quattro from France and the Italico from the UK !!!).

Each design have their pro's and con's and each are performing better in some conditions rather than others.  So the choice is yours.


So what do I need to start ?

Well there are really 3 options available to you :

1- you can buy a new IOM boats which are available to purchase directly from boat builders (list in our link page) varying from €800 to €3,000 depending on the design and the level of finish and equipment provided.

2- you can buy one second hand, IOM boats start from around €600 with a good choice of boat designs and level of equipment.  (our link page will direct you to some second hand boats for sale).

3- you can build one yourself using your own design (make sure it adheres to the IOM rules) or from the plans of recognised boat builders.


We would recommend that you talk first to club members to get some advice prior to buying your first boat (check our list of second hand boats available).  This is to ensure you get the best with your budget depending on what you want to do with it.


So what are they ?

They are remote controlled boats. They work exactly like full size ones. Both use similar equipment (hull, mast, boom, sails) the only difference is that they’ve no crew. All commands are controlled via a transmitter which transmits a signal to the receiver in the boat which in turns signals the rudder servo or the winch on what to do. IOM or International One Meter is part of the ISAF RSD (Radio Sailing Division) which governs all radio sailing classes.


Do they have to comply to specific class rules ?

IOM boats must comply to specific rules and are regulated by a governing body to ensure that all these rules are respected and thus ensuring fair competition. Here are some of the key requirements :


In a nutshell

One metre in length,

4 Kg in weight minimum

Max 3 different size rigs for various wind conditions

2 channels max. For controlling the sails and the rudder

No "expensive" composite material (carbon, kevlar, etc...) allowed in hull construction
