Welcome

Carolyn Shearlock

Hi! I'm Carolyn Shearlock. My husband and I have been living on a boat and cruising over 17 years and 13,000 miles, first on a Tayana 37 monohull and then on a 34' Gemini catamaran. Along the way, we sold pretty much everything we owned (twice!), gained a great boat dog, had a bunch of wonderful times and some adventures . . . and learned a ton about what does and doesn't work!

How Can We Help You?

I'm curious about the cruising life What is it, who does it, and what's it really like day to day?
I'm tempted — but is it realistic for my situation? My budget, my health, my partner, my life, my skills (or lack thereof)
I'm getting ready to go Buying a boat, getting insurance, planning to move aboard
I'm aboard and navigating the learning curve How do I make it the life I dreamed of?
