Momentum | 2012 Lagoon 450 F

The story of your boat

Our journey with Momentum began in December 2023 when we purchased her in Annapolis, embarking on a year-long Caribbean sailing adventure as part of my sabbatical from work. Despite our initial lack of sailing experience, this decision has transformed our lives in ways we never imagined.

The first few months in Florida were intense and rewarding. We immersed ourselves in acquiring ASA certifications and mastering crucial skills – from diesel engine maintenance to electrical systems and navigation. Simultaneously, we transitioned our daughters (10 and 11) to homeschooling, adapting to our new floating lifestyle.

This experience has been nothing short of extraordinary. It’s undoubtedly the most daring and incredible adventure we’ve undertaken as a family, bringing us closer together and profoundly changing who we are. The challenges we’ve faced and overcome have strengthened our bonds and broadened our perspectives in ways we never anticipated.

From Florida, we set sail for Grenada, where we plan to spend the next few months. As we continue to explore and grow, we’re also preparing to pass Momentum on to her next family. We hope to find new owners ready to embark on their own life-changing adventure and continue Momentum’s journey of exploration around the world.

Our time with Momentum has taught us that the greatest adventures often begin with a leap of faith. We’ve discovered strengths we didn’t know we had, learned more than we ever expected, and created memories that will last a lifetime. As we look to the future, we’re excited for the next family who will have the opportunity to write their own extraordinary story aboard this remarkable vessel.
