Painting Your Boat Like a Pro

Practical Sailor covers topside paints from top to bottom.

A high-quality finish begins with proper preparation, and Practical Sailor’s hands-on refinishing projects on crafts ranging from an 11-foot sailboard to a 41-foot Ericson offered our experts plenty of insight into prep-work challenges. Preparing the hull’s surface for painting is a laborious process, but if you review the primer on prepwork and our do-it-yourself notebook that accompanies our top-side paint test, you can save time and avoid the most common pitfalls. If you are set on a do-it-yourself spray paint finish, former technical editor Ralph Naranjo walks you through the process in a sidebar to his extensive, three-year-long topside paint test. These articles offer a good foundation for getting a high-quality finish without shelling out thousands of dollars for a professional paint job.

As Naranjo demonstrates in multiple test boat projects, probably the biggest challenge comes when working with two-part paints. These are usually more sensitive to temperature and humidity than single-part monourethanes or acrylic enamels, which typically are less glossy and less durable than two-part paints. The trick to getting a perfect two-part finish is achieving the right balance of flow and cohesion, so the paint does not sag, run, or orange-peel. This is why we recommend novices undertake a few practice projects like oars or a dinghy before tackling an entire hull.

The quality of your painting tools also makes a difference. For one of our test hulls (a Catalina 22), we used the two-person roll-and-tip method, which entailed one person applying the paint with a roller and the other tipping the rolled-on paint with a brush. If you want to take this route, our article on choosing a paint brush will come in handy. It compares high-quality natural bristle brushes to hardware-store varieties. We also offer a guide to caring for your brushes after using them. And if you plan to save some paint for touch-ups, we have a few tips on preserving leftover paint and varnish.

As the years go by, dulled linear polyurethane (LPU) finishes can be revived, but this requires special care. Our article on extending LPU life makes sure you avoid any mis-steps that can lead to premature LPU death.

Weve recently made open to the public our introduction article to the ongoing test of topside finishes. Presently, only subscribers can review our latest test report on topside paint.

For even more detailed advice on sailboat refinishing, check out Don Casey’s illustrated guide Sailboat Refinishing, which covers everything from choosing the right tools to getting a professional finish at half the cost. The book is available in our online bookstore. And if youre not interested in painting your hull but simply want to bring back its shine, our e-book on gelcoat restoration and maintenance tells you everything you need to know about reviving a worn fiberglass hull.

We’d like to hear about your hands-on experiences during do-it-yourself paint projects. If you have already undertaken a paint project, you can help fellow sailors through this process by posting your comment below or emailing our editorial offices at practicalsailor@belvoirpubs.com.

Darrell Nicholson, editor of Practical Sailor, grew up boating on Miami’s Biscayne Bay on everything from prams to Morgan ketches. Two years out of Emory University, after a brief stint as a sportswriter, he set out from Miami aboard a 60-year-old wooden William Atkin ketch named Tosca. For 10 years, he and writer-photographer Theresa Gibbons explored the Caribbean, crossed the Pacific, and cruised Southeast Asia aboard Tosca, working along the way as journalists and documenting their adventures for various travel and sailing publications, including Cruising World, Sail, Sailing, Cruising Helmsman, and Sailing World. Upon his return to land life, Darrell became the associate editor, then senior editor at Cruising World magazine, where he worked for five years. Before taking on the editor’s position at Practical Sailor, Darrell was the editor of Offshore magazine, a boating-lifestyle magazine serving the New England area. Darrell has won multiple awards from Boating Writer’s International, including the Monk Farnham award for editorial excellence. He holds a U.S. Coast Guard 100-ton Master license and has worked as a harbor pilot and skippered a variety of commercial charter boats.

  1. I recently repainted my trawler yacht using Epifanes mono urethane. The gloss was amazing. I used the roll and tip method. I struggled to get the fine brush marks to lay down and disappear. After conversing with the Canadian rep he informed me they now just recommend rolling, without the tipping off. They now recommend rolling over spraying as well! My final coat was done that way and the results were great. I have used Epiphanes competitor products (Interlux and Petit) with much worse results. In one case I painted a racing sloop 4 separate times and it glossed up only one of the four times. In another case a barrier coat litterally balled up and would not roll on pulling itself off as I rolled. Epifanes for me! You can see my video of the results on a facebook page I manage “Mainship Owners Page”
