Hi John, I would agree that cost certainly plays a part in less restricted classes but am not so sure hull construction or weight limit is the overbearing factor. Yes an IOM can be built to a reachable minimum hull weight. They can also be built strong and lighter than that minimum weight, carrying correctors carefully placed for improved performance.
In the Marblehead class there continues to be boats home built around the world that are more than competitive with any of the leading designs. Well built older designs such as the Paradox, Starkers and Skalpel to name 3 that go back 20+ years are generally of a similar or lighter hull weight than modern builds. As for cost and tooling, arguably the most successful M hull of recent times was built over a an inexspensive shaped foam plug. Of course a level of skill is required, but that is no different for any home build in any class.
That the bare materials to hand lay up a competitive home build M are comparable in cost to the bare high modulus carbon tubing for one mast, before any fittings, rigging or sails are added shows where the largest cost lies. Now multiply the rig number total by up to 6 and the cost of a hull is minimal by comparison.
That said, despite minimal promotion the M and 10R classes continue to have a solid following at National and International events in various parts of the world.
Great to see this new build taking shape and look forward to further updates.
Cheers
Brad
