Performance and design

The RS400 is designed for a wide crew weight range.^[5] The interior layout is simple with the principle control lines being led to either side of the boat, so that either helm or crew can adjust the rig control settings.^[6]

The light weight mast and mast bend can be controlled using a deck level screw and adjustable spreaders. Rake and sideways bend are further variable via the jib halyard.^[7] Both the main and jib are fully battened.^[8] The asymmetric spinnaker has an extending/retractable bowsprit that can be biased/offset/"rocked" to windward, allowing the RS400 to sail deeper angles offwind/downwind.^[9]
