 (btw, Lucas is also a bronze Medallist skipper in 470s for Argentina in

Lucas- “It all depends on tactics, but a good guideline I think is:
- Planing: it works when you do over 9.5 to 10 kts of boatspeed.
 
- From planing to wing-on-wing: if you are trying to plane and you are
 doing between 8.2 and 9.5 kts, wing-on-wing is probably the best mode.
 
- From wing-on-wing to VMG: if doing less than 8.2 kts of boatspeed while on the wing you are better off going displacement/ VMG mode.
