On a Personal Note

Thea began sailing in Desolation Sound in the Pacific Northwest after receiving her coastal cruising certification in her early twenties. Later in life, after cruising from Puerto Vallarta to Cartagena and back on a 51-foot Mikelson Cutter, Thea sold yachts for a brokerage in Nuevo Vallarta, Mexico, in 2010.

Relocating to Hawaii in 2012, she sold yachts from small sailboats, to large sport fishers and motor yachts in Honolulu. In Hawaii, she spent much of her spare time fishing on a 51-foot Viking sport fisher. She now owns and lives on a Lagoon 450F catamaran.

A retired attorney with a strong foundation in yacht sales and in luxury sales and management, Thea can easily and thoroughly understand your needs and find the ideal yacht for you. Her strong knowledge of sail and power vessels make her the perfect person to sell your yacht. She forms trusting relationships with her clients many of whom become great friends with her.

Thea is fluent in English, and speaks conversational Spanish and French. And she is a certified yoga instructor. 

Testimonials for Thea Koshman

The Barbers, Lagoon 440

We used Thea Koshman, Catamaran Guru, to sell our beloved Lagoon 440 catamaran. Thea was great to work with; she is responsive (emails, phone calls), she looks after the interests of her clients, she offers helpful suggestions and solutions to the issues and questions that will inevitably arise during the process. If we were to purchase another catamaran, we would not hesitate to use Thea.

Eric & Debbie, Matrix Vision 450

Thea was our stunning broker.

The brokerage owners, Stephen and Estelle, were amazing! I was blown away at the care and consideration they bestowed upon us!

They all truly went far above and beyond the call of duty when faced with a snag that was no fault of theirs.
