Is the Dwyer DM-275 mast section legal in the InterClub dinghy?
At present, NO! Only the Zephyr #1 section and the Kenyon B section are legal. Dwyer’s DM-275 section is nearly identical to the Kenyon, having very similar weight and moment characteristics (Kenyon – 0.89 lb/ft, Dwyer – 0.824 lb/ft). The Dwyer is also slightly less expensive (I think about $2/ft). It is unclear to me why this mast section is not allowed under class rules.
