1970-2025 Donzi® Ragazza 21 DL, No Tower or Arch Factory Original (OEM) Canvas & Covers, T-Topless™ Folding T-Tops, Shade Kit, TTopCover, T-Top Curtains, Bimini-Tops and Boat-Covers

Donzi®: We do not have OEM tops or curtains for Donzi® boats.

Factory Original-Equipment-Manufacturer (OEM) Canvas for Donzi® boats: RNR-Marine™ is a leading dealer for Ameritex® Fabrics, who patterned and manufactured Factory Original-Equipment-Manufacturer (OEM) canvas for Donzi® 26ZX and 28ZX boats from 2000 to 2002.

We produce new canvas (diagram explaining what each piece of canvas is called) in the Sunbrella fabric colors originally offered by Donzi® only. Note: Donzi® HIN = DNAsssssmbyy , where [yy] = model year. Specifications, care and cleaning of Sunbrella , and other canvas materials are detailed below. In some cases (if the boat mfgr is out of business for example) you can upgrade the windows to Strataglass coated clear vinyl (approx. 50-60 percent more cost), however the standard Eisenglass (clear vinyl) will last for many years with proper care, cleaning and storage. We utilize our library of 1,000's of patterns to produce new, "made-to-order" Factory Original canvas for your Donzi® boat. This is the same canvas originally offered from the Donzi® Factory and sold by your local Donzi® dealer (local dealers may only go back 5 years or so however, and charge local sales tax, which we do not charge except in SC and FL). No other canvas manufacturer has these patterns or the ability to produce the exact factory Original Equipment Manufacturer (OEM) replacement canvas and covers that were offered from the Donzi® Factory when your boat was new.

Please be sure that you have the Factory Donzi® frame or matching canvas.

Size #10 (5 teeth/inch) and #8 (6 teeth/inch) zipper comparison and measurement
There are no cancellations, refunds or returns on Factory OEM canvas, since it is all "made-to-order" for you. Some owners (and even dealers, when new) installed their own "after-market" Bimini Tops, T-Tops, Hard-Tops and Canvas, so please:

Compare your canvas or frame to the Donzi® factory OEM photos shown here,
Check for "Ameritex" or "Taylor Made" tags with Donzi® OEM part numbers on existing canvas,
Verify that your existing canvas has # 8 gauge zippers (factory original-equipment Donzi® OEM zipper size):
- #8 gauge zippers have 6 teeth per inch and will NOT zip to #10 zippers,
- #10 gauge zippers have 5 teeth per inch and will NOT zip to #8 zippers,
- See zipper size comparison photo at right,
- Please note that after-market canvas makers often use the large #10 gauge zippers.
- The zipper gauge size is actually the height of the teeth, 8mm or 10mm tall for example. (#8 has 8mm tall teeth and #10 is 10mm tall for example). Since it is very difficult to measure the zipper tooth height, the easiest way to measure zipper size is to count the number of teeth over 2 inches: a #8 zipper has 12 teeth over 2 inches and a #10 zipper has 10 teeth over 2 inches.

Additional Shade for Donzi® boats : When its hot you can never have enough shade. Our Boat Shade Kits (starting at $524.00 , SALE PRICE: $487.32 (End of Summer Sale)) extend shade over the cockpit or bow (can even be used like a Spray-Dodger) and can be put up or taken down in minutes.

Folding T-Tops to fit Donzi® boats: Our T-Topless™ folding T-Top` fits most Donzi® center console boats. This top lowers (or removes) in less than 15 minutes to store your boat in your own garage or storage building/shed, potentially saving $1,000's per year in storage costs (or let you pass under a low bridge). The T-Topless™ folding T-Top is made of solid, yet lightweight, 1-inch diameter welded 316 Stainless Steel tubing with Sunbrella® canvas and install in an hour on the Stainless Steel windshield grab rails of Donzi® center console boats.

Factory Original-Equipment (OEM) Covers for Donzi® boats : We offer Factory OEM Cockpit Covers (typically in durable Sunbrella®) to fit your Donzi® boat perfectly.

Custom After-Market Covers for Donzi® boats : We also offer after-market Carver® Custom-Fit™ Boat Covers (from $239), Styled-To-Fit™Boat Covers (from $229) and in Sunbrella® marine fabric (the best quality, breathable fabric for covers) as well as some excellent high-quality, but less expensive materials, that are designed as a precise fit using measurements taken from your particular model of outboard motor.

For Center Console boats, we also offer Universal (Not OEM) Center Console (No T-Top) Covers, Leaning Post Seat Covers and Reversible (Flip-Flop) Seat Covers.

A popular solution for boats with T-Tops are our T-Top Console-Storage-Curtains, which completely cover the front cooler seat, entire console and helm seats or leaning post (starting at $484.00 , SALE PRICE: $454.96 (Winter Sale)). This is a nice alternative to the factory OEM console-cover and OEM leaning-post or OEM pedestal-seat-cover, typically costing less than the OEM console-cover alone.

Since Donzi® did not offer a factory mooring cover for boats with a T-Top, we offer custom-fit, durable TTopCover® Under T-Top Boat-Covers and Carver® Over T-Top Boat-Covers for Donzi® center console boats with the Factory OEM T-Top or Hard-Top. We have patterned hundreds of boats and T-Tops, so search for your boat or email to see if we have patterned your boat

Although Stamoid® is made in a variety of colors, we typically offer only white (Ivory for Grady White®), as used on many yachts.

Water repellect Top Gun™ fabric is characterized by excellent strength, durability, tear and abrasion resistance, dimensional stability, UV and mildew resistance, and is backed by a 5-year Limited Fabric Warranty. We offer Top Gun™ in very few applications.
- Vinyl ... Some of our aftermarket Tops and Factory OEM canvas are offered in marine grade Vinyl fabric. Proposition 65 is a California law intended to protect consumers in the state of California from exposure to certain chemicals that may be harmful. The law requires that businesses notify Californians prior to sale if a product contains certain chemicals. The law also requires that the manufacturer label the product with a warning. Vinyl often contains the chemical Diisononyl Phthalate (DINP) which is on the list of chemicals known to the state of California to cause cancer, birth defects or other reproductive harm. DINP belongs to a family of chemicals commonly added to plastics to make them flexible (products such as garden hoses, athletic shoes, automobile and marine seating). Exposure occurs through ingestion, inhalation and, to a lesser extent, dermal contact. While such products are perfectly safe to use in their intended manner, the law still requires that we warn Californians of the presence of the chemical.
- RNR-Marine™ recommends cleaning your canvas or cover to maintain its original beauty and increase longevity.
Covers are made of a fabric with a weave that can "breathe" to prevent mold and mildew. Vinyl or vinyl coated fabric, such as Weblon®, Stamoid®, Top Gun® or SeaMark® are not recommended for covers, since the material does not breathe to ventilate the covered space. We offer covers (depending on boat manufacturer) in one or more of the following fabrics:
- Solution Dyed 100% Acrylic 9.5 oz./sq.yd. marine fabric is used for Console-Covers, OEM Seat-Covers, OEM Leaning-Post-Covers, Bow Covers, Cockpit Covers and Mooring Covers. This durable, 9.5 ounce per square yard fabric is colorfast and mildew resistant, and is backed by the Sunbrella® 10-year Limited Fabric Warranty. Sunbrella® is the premium cover fabric in our opinion, since it is tough, breathes and the fabric is woven with solution dyed acrylic fibers, which last longer than polyester and retain colors extremely well. Sunbrella® is made in the US (Anderson, SC) by Glenn Raven Mills®, and is offered for all of our Factory OEM canvas and covers, as well as our Carver® after-market Custom-Fit™, Styled-To-Fit™ Boat Covers and Bimini Tops.
- 100% Solution Dyed 9 oz./sq.yd. Polyester fabric (in Grey, Tan, Navy Blue or Black) is used for TTopCovers® T-Top/Hard-Top Boat Covers and T-Top Center Console Storage Curtains. Top-Notch® Elite® is breathable, reversible, water repellent, UV resistant, dimensionally stable (won't sag or stretch) and mildew resistant. Because the yarn is solution dyed, color fastness is very good. Top-Notch Elite® is backed by a 5-year Limited Fabric Warranty.
- 100% Solution Dyed 8 oz./sq.yd. Polyester fabric (in Navy Blue or Black) is used for T-Top Boat Covers and T-Top Center Console Storage Curtains. Weathermax-80® is 100% solution dyed polyester incorporating UV resistant characteristics for long-term color and strength retention along with excellent breathablity and abrasion resistance. The HydroMAX® finish raises the bar of hydrostatic performance and delivers unsurpassed water repellency, mildew and oil resistance without relying on environmentally unfriendly coating compounds. WeatherMAX® has anti-microbial properties and a minimum UV resistance of 1000 hours but only weighs 8.0 oz. per square yard due to the use of a filament rather than a spun yarn like acrylic fabrics. Excellent for anything from horse blankets to tough outerwear to marine grade tarps. WeatherMAX® is backed by a 5-year Limited Fabric Warranty.

Carver®'s own unique finish provides exceptional water repellency while maintaining breathability for the health of the boat. Made in USA by Glen Raven Mills® (North Carolina manufacturer of Sunbrella®) for Carver® Industries. Carver® Sun-DURA® is backed by a 7 Year Limited Warranty.
- Black Resilience™ is a proprietary tough, black or white stretchy fabric (like Spandex) with a quadruple coating on the outside to reflect the sun to keep things cool beneath. We use Resilience™ on our T-Top-Storage-Bonnet (1-Year Limited Warranty) and T-Top-Dry-Stack-Covers (3-Year Limited Warranty). This is the same fabric made for the US Government to cover fuel storage tanks in the desert to keep them cool. The Limited Warrnty on these products includes free repair for any damage caused by poor workmanship (excludes abuse).
- Some of our Factory OEM canvas is offered in ClimaShield® Plus fabric as offered by the boat manufacturer. ClimaShield® Plus is woven with Dowco®'s Color-Lok® polyester yarn (solution dyed so the fibers that make the threads are indvidualy dyed) to provide superior fade resistance, product longevity and durability.

- Poly/Cotton Duck ... 50/50 polyester/cotton "Duck" fabric (from Dutch "doek") is a heavy, plain woven blended fabric offering the advantages of both cotton and polyester fibers blended in one fabric. Cotton is a fully breathable fabric, which helps prevent mold and mildew in your boat. However, as the thickness increases, the breathability decreases. 100% cotton tends to rip and wear out easily, depending on the weave. Cotton canvas is a very durable and abrasion-resistant fabric, but it can be very thick and heavy. Polyester does not breathe, but it is very elastic and therefore tends to be very tear resistant. However, it is not as abrasion-resistant as cotton canvas. Poly/Cotton blend fabrics combine the strengths of the two fibers. Poly/cotton fabric is breathable, tear-resistant, and can be fashioned into abrasion-resistant fabrics, like canvas. We make many older Factory OEM Mooring Covers (to order) in Grey #6 weight (13oz per 36"x22" piece) 50/50 Poly/Cotton Duck fabric.
- Vinyl ... Some of our Factory OEM covers are available in marine grade Vinyl fabric. Proposition 65 is a California law intended to protect consumers in the state of California from exposure to certain chemicals that may be harmful. The law requires that businesses notify Californians prior to sale if a product contains certain chemicals. The law also requires that the manufacturer label the product with a warning. Vinyl often contains the chemical Diisononyl Phthalate (DINP) which is on the list of chemicals known to the state of California to cause cancer, birth defects or other reproductive harm. DINP belongs to a family of chemicals commonly added to plastics to make them flexible (products such as garden hoses, athletic shoes, automobile and marine seating). Exposure occurs through ingestion, inhalation and, to a lesser extent, dermal contact. While such products are perfectly safe to use in their intended manner, the law still requires that we warn Californians of the presence of the chemical.
open weave vinyl covered polyester "Standard Mesh Solids" fabric (very breathable) is used on Gear-Nets and Mesh Windshield-Covers. Although there are a wide variety of Phifertex® colors, most Gear-Nets and Windshield-Covers are Black, Grey or White.
Visors, Connectors, Spray-Shields, Enclosures, Side-Curtains, Aft-Curtains and Gull-Wings are typically made with a combination of canvas (above) and either:
- Flat, extruded 30-mil (0.030" thick, often called "30ga" or "30 gauge") clear, marine grade vinyl (often called "Eisenglass" or "Isinglass") as specified by the boat manufacturer.

- premium, flexible Urethane-coated poly-vinyl-chloride (PVC) sheet "glass" (60% higher cost) engineered to be ultra clear and resistant to the damaging effects from the sun's rays, environmental fallout and scratching from handling. It also blocks out the UltraViolet (UV) spectrum of light (90% UVA, 99% UVB, 99% UVC). Read more about Strataglass® advantages. Strataglass® is available in 20-mil (0.020"), 30-mil (aka 30ga = 0.030" thick), 40-mil (0.040") or 60-mil (0.060" = ~1/16") thickness. The 40-mil is available in a clear, light smoke or dark smoke tint, which is a special order (adds another 10% to the cost and 2 more weeks). We recommend 30-mil for fishing boats, since the thicker vinyl is hard to roll up offshore. Yachts may use 40-mil or 60-mil (even more costly) when the vinyl is seldom (if ever) rolled. Strataglass® claims a 5 year life expectancy (care & exposure dependent), but notes that many yacht owners see 10 or more years of use with proper care.
- RNR-Marine™ recommends cleaning and removing all clear-vinyl prior to trailering, to avoid the harmful efects of rocks, bugs and oils on the vinyl!
