Main yacht - fine
Commuter yacht - fine
Weekend yacht - you’re taking the piss now.
You need the weekend yacht if your main one is moored say in southern Spain and you cba’ed flying down at the weekend. It’s pretty much a necessity really.
I know, I really didn’t think this through. It fine being all noble and saying something like ‘people should have fewer yachts’ but clearly we all have different circumstances. If it means using the private jet less, then it’s probably better for the environment to sail there.
