Discover what many others already have…our store is a “true” discounter!
Our prices are often competative with Wal-Mart and Amazon.
“Got to say, I’m always impressed at the competitive costs of items in your store. In many instances items are less expensive than what I have found online. Much appreciated, especially when I realize that I’ve forgotten a key filter etc mid-service.”


At our store, we know you have many choices on where to make your boat supply purchases. That’s why we are willing to go above and beyond to earn your business.

Our People

With decades of boating experience, our friendly and knowledgeable staff will help guide you through most of your boat projects. From bottom painting to furling units and everything in between. We can offer advice, do the research for you, or steer you to the right resource such as our experts in our Service Department, to make sure you are purchasing the right product for the job at hand.

Product Selection

Our store stocks a comprehensive inventory for the do-it-yourself boater. Covering products from electrical to sailing and from fiberglass repair to plumbing, we pride ourselves on having the product that can fill most of your needs.

Stop in our office and ask for a full catalog.

To get the SUPER SAVER discount price, simply email with your part request and we will usually reply within 24 hours!

We stock many of the items in our catalog. The remaining items can be delivered in as little as one day with no commitment! We will just throw it back on the next truck if you don’t like it.


While we may stock many products in the store, we cannot possibly carry it all. That’s why we have multiple distribution centers delivering to us four times a week. This allows us to put thousands of products in your hands in as little as one day. Feel free to browse our catalogs to find the exact product for your needs. We are also able to quote you our discounted price immediately by phone or in person on most items so there are no surprises when your part arrives. We also specialize in those hard to find parts from marine plywood to custom sailing blocks and even boat manufacturer specific gelcoat as well. Stop by or give us a call to see what we can do for you!

Discounted Pricing

Probably the biggest surprise of all is that our pricing is very aggressive even on special orders and most often beats our competition! And if it doesn’t, we’ll gladly tell you and lead you to the lower price. Feel free to shop and compare or better yet, let us quote your next product need.


Besides being right in your back yard, you can call in or email your order ahead of time and we’ll have it waiting for you when you arrive.
