One Design Racing
The J/109 was originally developed as a one design cruiser racer and one of the principal attractions of the class for many is the opportunity to race head to head against each other in equally matched boats, with victory going to the boat first to cross the line.
In order to compete in One Design events, competitors must be members of their national Class Association and comply with the current Class Rules (which can be found on this website under the “Documents” link on the menu). The class rules aim to keep the boats equally matched by specifying the maximum size and number of sails that can be used in any regatta and requiring the boat to be equipped according to the original specification. The rules also limit the total weight of the crew (excluding the owner) to 600kg although this is relaxed for certain regattas like Cowes Week in order to encourage the participation of the whole family in the event.
Most organising clubs require at least 6 or 8 entrants to run a One Design J/109 class within their regatta and the key events through the season are:
- Helly Hansen Warsash Spring Series and Spring Championships in March and April
- RORC Vice Admirals Cup in May
- Portsmouth Regatta in June
- J-Cup dates vary year to year
- Taittinger Royal Solent Regatta in July
- Lendy Cowes Week in early August
- Dartmouth Royal Regatta in late August
The requirement to get more than 6 or 8 J/109s to the start line in compliance with the class rules for a One Design event can be a challenge, particularly away from the Solent which has the greatest concentration of active J/109s. Consequently, many J/109s participate in handicap racing under IRC, a rating rule used to handicap different designs of keelboats allowing them to race together.
This opens up a very broad range of racing options around the country racing both inshore and offshore, fully crewed or short handed. J/109s are regular and successful participants in:
- Round the Island Race a race around the Isle of Wight, held in early July
- Royal Southern Yacht Club Summer Series
- Royal Southampton Yacht Club Double Handed Series
- RORC, including the Fastnet Race
Obtaining an IRC Rating
In order to compete in an IRC race, a yacht need not comply with the J/109 UK & Ireland Class Rules, but does need to be in possession of a valid IRC Rating. The process need not be complicated and is described best by the rating office themselves here.
One Design Rule Changes
As participation in IRC racing by J/109s has grown and the advantages on the IRC rating of reducing the sailplan been greater appreciated, many owners of J/109s have found themselves needing to maintain two different sail inventories in order to compete one weekend in one-design racing and the next in IRC events.
As a result, the class has agreed to amend the rules governing one-design racing enforcing a switch from overlapping Genoa’s to non-overlapping jibs, allowing in-haulers to sheet the jib further inboard and adding the flexibility to hoist the jib on a fixed tuff luff or to use the existing furling headfoil as each boat chooses.
The objective of the change is to bring the configuration of the boat used for one design racing much closer to the configuration considered by most to be optimal for IRC handicap racing, which will make it simpler and potentially less expensive for boats to participate in both disciplines.
The changes came into force for the season commencing 1st January 2021. After that date, overlapping genoas will no longer be permitted for one-design racing.
