Querido cofrade,

He calculado el SA/D para tu barco y sale 21,19. Dentro de un rato repaso los cálculos y los escribo aquí para que todos puedan repasarlos también.

Ratios below 14 are suited for motor sailers, from 14-17 for ocean cruisers and from 16-18 for typical coastal cruisers. Ratios over 18-20 are seen on racing dinghies, inshore racers and ocean racing yachts. The more extreme screamers can have very high SA/D ratios indeed; My 60 foot design, WILD THING, had a SA/D ratio, based on 100% foretriangle, of well over 30, depending on her displacement at the moment. Her displacement varied widely as she could carry 8,000 pounds of water ballast in tanks on the windward side.

Tienes superficie vélica de un Formula 1. Yo creo que no está mal, sobre todo si navegas en una zona de poco bien y protegidas. Ya sabes que tienes que reducir vela cuanto antes!

No se de donde lo has sacado pero yo tengo otras referencias


Sail Area / Displacement Ratio (SA/D) range of values:
16 to 18 Heavy offshore cruisers
18 to 22 Medium cruisers
22 to 26 Inshore cruisers, racing boats
26 to 30+ Extreme racing boats



El calculo de SA/D me sale muy ·igual 21,39 que cae dentro de los Medium cruisers


············· Sail Area in sq. ft.
SA/D = -------------------------------------
·············· (Displacement / 64)^0.6666


Los 48,5 m2 equivalen a 522,05 pies cuadrados
y los 3500 kgr equivalen a 7716 lb2.876 oz

Hay que tener en cuenta para los cálculos:

As with the D/L ratio, the displacement figure used must reflect the real-world weight of the boat in the water.
