Woke up with the expectation (based on the forecast) I would go wave sailing with the 5.3 but instead I had a hard time to keep on planing with the 8.4. A bit disapointing but still nice day on the water, even when it was raining. Tried to test the Select S12 versus the Select VMAX, both 43cm but due to dropping of the wind the comparison was not fair.
