When I was younger I tried mightily to overcome vertigo so I could fly helicopters. Unfortunately I was sick every single time. I think the inner ear sensitivity has served me well operating heavy machinery, but when the visual perception doesn’t match the sense of motion in my head, immediate flight response kicks in and evacuation ensues. I plan to attempt a short cruise soon. Hopefully I can do it without Dramamine or spending all my time below! I love following you and living it vicariously though. Maybe one day. PV.
