Colorado’s Cobalt & Boston Whaler Dealer Since 1976
New Cobalts and Boston Whalers, Yamaha outboards, quality pre-owned boats, and a full-service shop that has kept Colorado boaters on the water for five decades.
The new 2027s are here, in the showroom and ready to climb aboard. Tap Ask on any boat to request your one-on-one pricing consultation, and we will walk you through pricing.
From the Montauk to the Outrage, every Whaler is foam-filled and unsinkable. Tell us how you fish and cruise, and we will spec and factory-order the right boat, then rig and service it right here in Littleton.
We sell the full line of Yamaha outboards, from portable power to high-horsepower offshore models, and we stock the most commonly used genuine Yamaha parts and accessories to keep them running. Buy your Yamaha here, and the same techs who rig it will service it for years.
Factory-trained technicians, honest timelines, and a shop that treats your boat like its own. It is why our customers keep coming back, season after season.
Fall booking is open. Winterization and shrink wrap appointments fill up fast once the first cold snap hits. Book yours now and skip the November rush. Call 303-791-6100
