Coastal Marine Center Inc

Our Headquarters

Same Location Since 1988

Stop by and check out our full inventory of new and pre-owned boats. Our sales department provides brokerage services and our Mercury Certified service center will meet all your maintenance needs. We offer full storage for your convenience if you decide to leave paradise for a short period of time, or just need a place to keep your boat year-round. Land storage is a lot more affordable than a rack-o-minimum with less than 2 miles to travel to either boat ramp in the area. Our completely fenced-in area is well-lit and secure.

Our history

1983-1988

Coastal Marine Center's founder, Todd Garthwait, established a strong foundation in marine service and customer relations working at other local marinas.

1988

Todd establishes Coastal Marine Center Inc as a full-service, Mercury-Certified Dealer, offering new and pre-owned boat sales as well as a brokerage service.

1988- 2025

Surviving the test of time, Coastal Marine has served its customers at the same location for the past 38 years. Shortly after its establishment, Mercury recognized Coastal Marine Center as a "Premier" Dealer, assuring you that we have all the specialty tooling it takes to get the job done right the first time and keep you on the water.

We want all of our customers to have the Florida lifestyle experience of "Happy Boating". Here's how we do our part to make it happen:

Honesty: We'd rather tell our customers the truth and lose a sale than jepordize our reputation, or more importantly, the safety of our customers on the water.
Integrity: We do our part to make sure that any vessel on our lot is worthy of being represented by Coastal Marine. If a boat is junk, you won't find it for sale here.

Clients say

Dave Summerour, greeted us, my wife and I, and we immediately felt very comfortable with him. He didn’t try to sell us anything, he just answered all our questions, or got answers for us on every concern. If I ever need anything boat related again, he will be the first person I contact. It was a real pleasure doing business with him and yes, we did buy a boat from him. Highly recommended!!!
Dave - Kaw City, OK
