It seems you have not the seaworthiness of multihulls in great account
No, I don't think that is the reason. They could limit the admissible size. I guess it is more conservativism and the rich guys with the big boats not wanting smaller cats with 1/4 of the crew to finish ahead. On all great European classics it took time to make multihulls admissible.
Anyway it is a shame because at that time of the year, with frontal winds, the monohulls would give fight to the multihulls. It would be a much more spectacular race.
