Performance Ratios

On the numbers, DH550 rates as high-powered (SA/D 25.2).

Ratios use published displacement (often light ship) and reported sail area; see Sources & methodology.

SA/Displacement (Calculated): 25.20

SA/D 25.2 — high-powered. Sail area relative to displacement: the higher the number, the more sail the boat carries for its weight, which means more power in light air.
