More than one way to skin a cat.
I can waterstart a 5.0 sail in 10 without grabbing below the boom.
OTOH, I can windsurf in 20+ winds and never fall more than 3 times in 5 days, making jibes every minute, and doing one jump a run.
I say "every minute" because I'm 72 and get out of breathe from activity. This with sub 100 liter boards planing every run.
I was waterstarting my 1st day in over 15 mph wind, 1st week.
