PHANTOM 377 vs 320

Hey, friends:

I want to buy a new raceboard, but I´m not decided between the Phantom 377 and the Phantom 320. I am 48 years old, and want it to do large travels (29, 30 miles) in sea. I sail for 30 years. Good level. These are my questions:

- Speed in planning conditions (max speed)
- Speed in non planing conditions
- Entry to early planning (min wind for planning with 8.6 m)
- Facility in high wind (max wind for control it with 6.5 m sail)

Thank you in advance
