New Boat Upholstery, Repair Boat Seat Cushions
Show Your Style With Stitching
There's more to marine upholstery than fabric and foam. The method of stitching, for example, can make a big difference in water resistance, performance and style. Here's what you need to know.
When fabric is simply draped over the foam it's called Waterfalling. This method requires fewer seams, so it tends to repel moisture and debris better than other techniques. Some boat owners prefer the rounded edges of a waterfalled cushion.
The seams in a waterfalled cushion are often concealed or minimized using a technique called Blind Stitching. This is a single stitch line with a plain seam. Blind stitching is popular with boat owners who want their upholstery to have a clean, streamlined look. The seam allowance under a blind stitch can fray, so the fabric's edges are usually serged or "hot knifed".
Top Stitching is another popular technique. A marine top stitch is a blind stitch offset with a parallel decorative stitch. The double line gives the top stitch added strength. This method is great for boat owners looking for crisp edges and secure seams. While a top stitch is strong, it's not waterproof.
A Marine French Stitch looks a little like a baseball seam. Some customers prefer a French stitch to decorative welting (see below). This technique starts with a blind stitch. The two seam allowances on the reverse side are then folded over and reinforced with fabric backing. The backing and seam allowances are held in place with a double line of decorative stitches. A French seam allows the fabric to lay flat, but it's the least water resistant stitch.
Strictly speaking, a Corded Seam or Welt is not a stitch, but it's a popular way to "dress-up" a seam. A welted edge starts with a strip of fabric wrapped around a cord. The finished cord is then sandwiched inside a blind stitch to enhance the cushion's appearance. Some prefer the look of a welt, but there's a downside. Unless you're careful, a welt will collect dirt. What's more, normal wear and tear — sliding back and forth across the cushion — can abrade the welt. It's not a big deal, just something to keep in mind if you prefer a welted edge.

Naugahyde® Sample Colors & Textures
The vast array of vinyl samples in our showroom have one thing in common; they're premium grade vinyls from established manufacturers such as Naugahyde®.
Naugahyde is a pioneer in coated fabrics. The company's orginal vinyls had a reputation for cracking and fading in harsh environments. Today's Naugahyde is nothing like the old stuff; it's a popular, superior quality vinyl with outstanding durability and exceptional performance. Here are just a few of the colors and styles Naugahyde® offers for boaters. Roll your mouse over the color swatch to display its name:
Manufacturing a V berth cushion can be challenging. For one thing, the shape of a V berth varies from boat to boat. Cushion configuration, size and density also differ based on a boat owner's preferences.
Here's a seven piece V berth we built for a Sea Ray owner. As you can see, each cushion for this V berth is a different shape. They fit together like a jigsaw puzzle, so correctly sizing each cushion is critical.
Custom Fit V Berth
Selecting the right fabric is just as important. Many boat owners prefer Sunbrella®. Sunbrella's marine fabric is manufactured from solution-dyed acrylic, so it doesn't fade or change color in a demanding marine environment. It can be a little on the stiff side, however. The fabric we used for this V berth is much softer; 100% woven polyester with a Crypton finish. In addition to being soft, it's extremely durable. It's also stain, fade, abrasion, bacteria and odor resistant. In other words, perfect for this application.
Sea-Doo Seat Covers
Sea-Doo, best known for its line of sporty personal watercraft, also manufactures speed boats. Speed boat seats take a lot of abuse during the summer. It's not uncommon for Sea-Doo seats to need repair every two or three years, especially if teenagers are bouncing around the boat.
We fabricate custom replacement seat covers for all speed boats, including Sea-Doos. But, if a boat owner likes the color scheme of their upholstery, it may be more cost effective to simply order an identical replacement seat cover kit.

Sea-Doo Seat Covers
In this instance, the seat cover stitching ripped, exposing the foam padding to destructive UV light. The boat owners put off repairs until the end of summer. By the time they brought the seats to us, the foam was pretty well shot. Instead of restitching a couple of seams, the cushions needed to be rebuilt and both seats needed new covers.
Fortunately, there was a Sea-Doo seat cover replacement kit available, which kept repair costs down. We rebuilt the damaged foam cushions, installed a set of identical covers and that was that; the seats were good as new.
Pleated Sun Pad For Seaquest
Here's a custom-designed sun pad we created for the bow of a 42 foot Sea Ray. It's fabricated from white and light grey Sequest Vinyl, a durable marine grade vinyl.
The pleated sun pad features a bolstered headrest adjacent to the windshield. The edges are also slightly raised.
There's a hatch built into the SeaRay's bow directly above the V berth. This ventilation hatch doubles as an emergency exit. Since the boat is a privately owned pleasure craft, there's no requirement to have a workable V berth hatch.
For safety reasons, we recommended keeping the hatch functional by building a rip-away cover into the sun pad. We used Velcro® so it easily pops open.
During the off season or when inclement weather strikes, it's easy to remove and store the three piece sun pad below deck or elsewhere.
Color-Matching Boat Cushions
Not all cushions in a pleasure craft wear at the same rate. If passengers prefer sitting in the stern, those seats wear faster than cushions elsewhere. Since there's no sense reupholstering all the seats when only some are damaged, the challenge becomes choosing a vinyl that matches the color and texture of the original fabric.
It's not as easy as you may think. Take the color white, for example. White comes in scores of shades and tones. Some are a little more "blue" than others. Some appear slightly warmer. It's sort of like the difference between fluorescent tubes and standard incandescent bulbs; the light from both are "white", but you definitely notice the difference.
Marine Grade Vinyl
We carry hundreds of vinyls and acrylic-based marine grade fabrics. We'd be happy to suggest a color and pattern to reupholster a boat cushion, but ultimately the customer makes the choice. Whatever the choice may be, you can be sure that any boat cushion reupholstered by Mac's will be durable and flawless.
Bow Cushions For Yacht
Here's an eight piece bow cushion we recently built for a 105 foot yacht. Bow cushions, like V berth cushions, can be challenging. Each bow tends to be a little bit different angle, size and shape. The striped fabric in this picture helps illustrate why correctly sizing the cushions is so important.
Notice the bottom two cushions on the far left. Cushion 'B' is rectangular; the parallel stripes extend all the way down the cushion. At first glance, Cushion 'A' also appears retangular, but look closer and you'll notice how one of the stripes on the cushion doesn't go all the way. That's because this cushion is slightly curved where it meets the gunwale. A less experienced trimmer might have missed this
Ultraleather™ For Luxury Yacht
When the owners of the luxury yacht Southern Cross based near Santa Barbara decided to homeport a second yacht here in Puget Sound, they called Mac's Upholstery. They wanted to upgrade their interior in royal blue.
Since money was not an object, we upholstered a number of pieces on board the yacht including an eight piece bridge settee, a nine piece galley settee, the captain's bunk and a pair of helm chairs. Everything was reupholstered in Ultraleather®. While substantially more expensive than standard vinyl, Ultraleather® is perfect for a luxury yacht.
Reupholstered Helm Chair
Reupholstered Helm Chair
Ultraleather® has the rich look and supple feel of real leather, but it's easy to clean and a lot more durable. It comes in a range of colors and textures.
Before upholstering the helm chairs, we replaced the foam. It's important to use the right kind of foam, especially in a demanding marine environment. If boat or yacht seats are exposed to the elements we often recommend Dryfast™ or EZ-Dri™ Foam. They're large cell foams designed to shed water. In this case, large cell foam wasn't necessary – all the pieces we upholstered were intended for the bridge and salon.
Seat Insert Repair
There's usually plenty of action onboard a ski boat; passengers running around the deck, hopping in and out of their seats. Upholstery can wear out fast. As you can see (top row), this ski boat bucket seat was in desperate need of repair. And not just because of normal wear and tear. It ripped because the original vinyl was thin and stretched too tight.
Damaged Ski Boat Seat
Damaged Ski Boat Insert
The bolster arms were undamaged and the foam was still in good shape, so we focused our attention on the damaged insert. Instead of repairing it with the same substandard material, we used a stronger vinyl with a little bit of stretch. We also increased the seam allowance so there was more "give". After repairing the insert the seat was good as new.
How Not To Build Marine Cushions
Every once in a while we come across a real head scratcher; these boat cushions, for example. They're fabricated with EZ-Dri® foam. EZ-Dri is a stiff foam with large air pockets. Instead of absorbing water the way conventional cushions do, the air pockets in this foam are engineered to shed water.
Original Boat Cushion
Plastic Under The Cover
The people who fabricated these boat cushions wrapped the EZ-Dri foam in waterproof plastic. Since EZ-Dri is designed to absorb and discharge water, covering it with plastic is counterproductive. Instead of draining water, the plastic cover created a perfect environment for mold and mildew.
Ez-Dri & Dacron Layer
And that's not the only thing wrong with these cushions. The white material covering the foam is Dacron®. Dacron is used to soften the crown of a cushion. Trouble is, these cushions were manufactured with the Dacron underneath the foam instead of on top. It doesn't do any good that way.
Before fabricating new covers, we cleaned and re-engineered the cushions so they worked right.
Boat Carpet Replacement
In addition to marine upholstery and boat cushions, we install custom snap-in and glue-down carpet for any size pleasure craft.
When the owner of this 19 foot Bayliner Capri needed new carpet, he dropped by our showroom to check out different color and style combinations. In the end, he decided to stick with the original rubber-backed burgundy. We ordered the carpet and went to work.

Bayliner Capri After New Carpet
After sizing the replacement carpet, we stripped the old flooring, scrubbed and prepped the fiberglass deck, then began the actual installation. This is where experience counts. Carpeting a boat is a lot different than carpeting a living room. Marine carpet needs to be a perfect fit; there's no floor molding to cover frayed or misaligned edges. What's more, this sort of flooring doesn't stretch the way residential or commercial carpeting stretches. You have to get it right the first time. As you can see, our guys nailed it.
Why We Don't Use Cheap Fabrics
Customers sometime ask why we only use marine grade fabric when upholstering boat interiors and cushions. The pics below help illustrate why. The first two show a standard grade red vinyl purchased by a customer to reupholster his boat cushions. The vinyl looks and feels great, but look what happened when we stitched through the material.
As you can see, the vinyl chipped around some of the thread holes. Adjusting thread tension didn't solve the problem. The vinyl face and thin backing on this fabric simply couldn't cut the mustard.
Standard Grade Vinyl
Marine Grade Vinyl
The vinyl we use is more durable. Sewing this fabric into cushion covers was a breeze — the stitching turned out perfectly.
You'd think the better vinyl would cost more, but not in this case. Our superior quality marine grade vinyl turned out to be less expensive. So, be sure to contact us before buying lousy fabric from somebody else.
Our craftsmen fabricate marine cushions with the finest foams and fabrics. But, even using the best materials, wrinkles are inevitable.
Eliminating wrinkles is one of the biggest challenges we face when fabricating custom marine cushions. Steam is the best way to get the wrinkles out. This video shows we do it.
Quality In Every Detail
Generic boat cushions are easy to make. Fabricating premium quality, custom-fit boat cushions require the skills of a maritime upholstery craftsman. Here's an example of how pleasure boat cushions manufactured by Mac's are superior.
We only use durable, marine grade vinyl
Using two Velcro bands instead of one ensures cushions stay put even in rough seas
Seams are meticulously stitched using heavy-duty thread
To maximize air circulation, we drill a series of precision vent holes in the back of the cushion
Gusseted zipper pockets keep the zipper slider in place
Our premium quality upholstery and marine foams last years longer than standard foams
Recover Grady-White Cushions
If the owner of this Grady-White had waited any longer to fix the onboard cushions, it might have been too late. As you can see from the first two pics, the vinyl was already ripped to shreds and the foam was deteriorating.

Recovered Boat Cusion For Grady-White Fishing Vessel
After repairing the damaged cushions with superior quality foam, we covered the cushions with marine-grade vinyl. Recreating the pleated backrest for the aft bench was a little tricky, but our craftsmen did a great job. They're the best in Seattle. As always, the reupholstered marine seats turned out great.
Bolstered Marine Cushions
Bolstered marine cushions are among the most difficult to upholster, especially when they're long and contoured. Not only are these Yamaha speedboat cushions hard to make, they require a fabric that's both tough and stretchable.
Cushion With Sharp Curves
Wrinkled Fabric Before Steam
Steam Smooths The Fabric
Spradling Vinyl manufactures a fabric with a flexible backing. It's called Softside™. Softside vinyl is durable and easy to shape. It's ideal for upholstering contoured cushions like these. There are nearly 300 colors and patterns. Here's a link to the company's website. The boat owner selected Zander Pearl Grey and Zander Ivory.
Even with the perfect fabric, upholstering a monster cushion with bold curves requires plenty of elbow grease. You have to make sure the fabric tension is evenly distributed then use lots of steam to smooth the wrinkles.
Beneteau Sailboat Settee
Here's a striking example of how new upholstery can transform a run-of-the-mill salon sette into something extraordinary.
Compare the original settee from a 42 foot Beneteau sailboat to the new one beside it. Look closer and you'll discover subtle design improvements, beginning with the cushions.
We improved the seating deck by building a foam ridge into the edge. The foam ridge not only cups a passenger snugly into the seat, it lifts their legs a couple of inches, reducing lumbar strain. We also contoured or angle-cut the back cushions for added confort.
Main Salon Starboard Sette, 42 Foot Beneteau Sailboat
Rather than snap fasteners, we used velcro. Velcro allows more flexibility in cushion placement. The notches you see in the cushions accommodate an arm rest and a mast cable. They're engineered to fit like a glove.
As always, we use only the finest marine-grade foams and fabrics. For this settee, the boat owner selected striking Mediterreanean colors from Sunbrella's marine fabric collection.
The reupholstered settee is snug, looks great, and fits the salon perfectly. And thanks to our design improvements and craftsmanship, it'll last for years.
Using Design To Fight Mold & Mildew
Seattle's damp climate encourages mold and mildew. When you factor in all the nooks and crannies found aboard boats, controlling mold can be a real challenge. Mold is not only unsightly and destructive, it's a health hazard.
Mold & Mildew Collect In Seams
Redesigning Cushion Cover
Sleek & Sanitary
If a boat owner can't keep a cushion dry, we recommend the next best thing – removing dark places where spores and grime collect.
One way to do that is by eliminating seams. In this case, we replace moldy tri-panel cushions with flat foam. Flat, symmetrical surfaces require fewer seams than something fancy. By removing seams, these freshly upholstered cushions not only look sleek, they now resist mold and mildew.
If you're considering new boat carpeting or marine flooring, you might want to check-out a new product called Infinity Luxury Woven Vinyl®. This stuff is truly amazing. It's not only beautiful, soft and flexible, but extremely durable. It features a unique, heavy-traffic rated backing system ideal for indoor and outdoor use.
This fabric is UV stable so it resists fading. Antimicrobial technology prevents bacterial growth. Soil and stains are easily cleaned reducing the long term maintenance expense compared to other floor covering options. We've posted pics of the current fabric collection below and we have samples at the shop. Here's a link to the manufacturer's website. Definitely worth looking into as a better alternative to marine carpeting.
