You deserve the pride and prestige that goes with that boat. Enjoy it, and don't apologize to your wife -- no doubt she appreciates your brilliance too.
I'd love to take you for a ride, if we ever get the chance.
As for giving the tour, we also get lots of attention and questions about our Dragonfly tri. It's kind of like having a dog in that it can be an ice breaker and conversation starter. We've met some nice people in our travels.
