On an open center console, marine vinyl goes on anything you sit or lean on in the weather, solution-dyed acrylic canvas goes overhead and over the boat, acrylic upholstery fabric suits softer cushions and pillows, and the look of leather is best delivered with synthetics built for marine and outdoor use. Each material is good at some jobs and wrong for others, and putting it in the right place matters as much as picking a good one.
Here is how we think about each one, with the makers' own descriptions so you can check us.
Marine vinyl: the seating workhorse
Marine vinyl is a coated fabric: a vinyl face over a fabric backing, often finished with a protective topcoat. It sheds water, it wipes clean with mild soap, and the marine grades are made to live in sun and salt.
Sunbrella lists where its Horizon marine vinyl is best used: cockpit seating, captain's chairs, gunnel pads, tower cushions and leaning posts. On a high-performance center console, that is most of the interior: the helm and companion seats, the leaning post, the bolsters, the coaming pads and the bow cushions.
The label matters. A Marine Fabricator article on choosing seating materials quotes a supplier saying vinyl specifically labeled "marine" will outlive other vinyls, and warns that non-marine vinyls deteriorate rapidly in sun, wind and rain. Marine grades carry the mildew resistance, UV stability and cold-crack ratings that a furniture vinyl does not.
The marine vinyls we work with are Spradling, Morbern and Sunbrella Horizon. Which one goes on your boat depends on the colour, the texture and the look you want, and on whether you are matching the factory or changing it. Our guide to choosing marine vinyl and fabric goes through how we decide.
What vinyl is not good at is breathing. Spradling's own guidance is that seats should be built so the foam does not become saturated, dries out quickly if it does get wet, and is vented so trapped moisture can escape. That is why the foam, the seams and the drainage under the vinyl matter as much as the vinyl itself.
Acrylic canvas: overhead and over the boat
Canvas covers the jobs where a material has to shade, shed water, move in the wind and still let air through: T-top and bimini canopies, enclosures, console covers, seat covers and full boat covers.
Sunbrella describes its marine canvas as made for Bimini tops, dodgers, sail covers and other custom shade, and as water-repellent and mold-resistant. Its fibres are solution-dyed acrylic: the pigment goes into the fibre before it is spun, so in Sunbrella's words, the colour you choose is the colour you keep.
The other reason canvas belongs on covers is that it breathes. Sunbrella says its marine fabrics allow air to pass through, and Spradling's own advice to owners is to cover the boat when it is not in use while allowing venting so moisture is not trapped underneath. That is what you want from anything that sits over your interior for days at a time.
We cover tops and covers in detail in our marine canvas guide, and you can see our canvas work here.
Acrylic upholstery fabric: soft cushions and pillows
Acrylic also comes as an upholstery fabric, softer and more textured than canvas. Sunbrella lists its Marine Upholstery fabrics as best for cushions, decorative pillows, sunpads and berth covers.
The trade-off is that a fabric is a fabric. It has a softer, more relaxed feel than vinyl, but it does not wipe clean the same way. Sunbrella's own care guide notes that after cleaning with a bleach solution, the fabric needs retreating for water and stain resistance, and that bleach may discolor fabrics that are not Sunbrella.
On a performance center console that gets wet at speed, the primary seating belongs in vinyl, and fabric suits the places where comfort matters more than washdown: a sunpad that is covered when not in use, throw pillows, or a cabin.
Leather: the look, done in materials built for a boat
Owners ask for leather because of how it looks and feels. On our builds, the leather-look options are synthetics made for marine and outdoor use.
On our top tier, the Signature Bespoke Edition, the options include Ultraleather and Alcantara:
- Ultraleather is a polyurethane fabric from Ultrafabrics. When it launched indoor and outdoor collections for the marine market, Marine Fabricator reported their claims of protection against fading and discoloration, an EPA-registered anti-mildew defense, and resistance to cracking from temperature changes.
- Alcantara offers an outdoor palette, which it describes as showing exceptional performance in breathability, colour fastness and, above all, resistance to atmospheric agents, salty air and seawater.
On the Premium Sport Upgrade, we use a cool-touch silicone fabric. Carbon-fibre textures also sit in the top tier for owners who want a technical look rather than a classic one.
These materials are not interchangeable with marine vinyl on every surface. Placement still matters: which pieces see direct sun all day, which get sprayed at speed, which are under the T-top. Talk it through with us before you choose.
The floor is its own decision
Underfoot, the choice is usually between EVA foam decking and marine carpet, and that decision has its own trade-offs. Our EVA decking guide covers it, and you can see our EVA decking and marine carpet work.
Where each material goes, at a glance
| Part of the boat | Where each material usually belongs |
|---|---|
| Helm and companion seats, leaning post, bolsters | Marine vinyl, or a marine-rated leather-look synthetic on top-tier builds |
| Coaming pads and gunnel pads | Marine vinyl |
| Bow cushions and sunpads | Marine vinyl, or acrylic upholstery fabric where it is covered when not in use |
| Throw pillows, cabin cushions | Acrylic upholstery fabric |
| T-top or bimini canopy, enclosures | Acrylic marine canvas |
| Console, seat and boat covers | Acrylic marine canvas |
| Decks | EVA foam decking or marine carpet |
Warranties follow the material
Manufacturer material warranties, where any exist, are passed through to you. Our own craftsmanship warranty sits on top of that: a "two (2) year limited warranty covering failures in stitching, seam binding, and direct installation craftsmanship from the date of final delivery. This warranty is transferable: if the vessel is sold during the warranty period, the warranty passes to the new owner for the time remaining, measured from the original date of final delivery." Budget-tier work carries no craftsmanship warranty, and the terms exclude damage from improper cleaning, including harsh bleach and high-pressure washers. Full terms are on our terms page.
