Why choose Dowco Marine products?

All Dowco custom marine covers, enclosures, and tops are manufactured to exacting specifications using industry-leading digital technology. This guarantees that all our products are made to fit... the first time... every time!

All marine products have extra sewn-in reinforcements for increased protection at wear points and sharp edges. Dowco warrants all of its products against manufacturing and material defects. All covers provide excellent protection from sun degradation, rain, and airborne debris. The snug fit helps to keep the inside of the watercraft clean and protected from bird droppings, tree sap, leaves, and small animals which can stain or damage your investment.

ClimaShield® Plus

2x Stronger & 3x More Water-Resistant

Dowco’s ClimaShield® Plus is a 7.5 oz, 600 denier solution-dyed polyester fabric providing superior UV protection and fade-resistance. The woven fabric is further enhanced with Durable Water Repellent (DWR), plus a urethane undercoating to increase longevity and durability. The anti-microbial coating makes the material highly resistant to mold and mildew. This top-quality fabric is highly resistant to shrink or stretch ensuring a tailored and secure fit.

Better Fade Resistance

Most fabrics are first woven from yarns with color dyes laid on top of the woven fabric as a coating. ClimaShield® Plus fabric is made with yarns dyed with Color-Lok® technology where the dye is impregnated into the yarn prior to weaving. This process not only significantly increases the fade resistance of the fabric but also eliminates the possibility of color transfer or "rub-off" to other materials.


Designed for the ultimate in wear resistance.

Dowco’s premium NauticShield fabric, a heavy-duty, 10.7 oz, 600 denier polyester features waterproof top and under coats. The resulting high-tensile strength, tear-resistant fabric is completely waterproof, UV protected, and highly fade resistant to maintain its color and good looks.


How can I prevent mold & mildew on my product?

ClimaShield® Plus and NauticShield marine fabrics contain antimicrobial agents that are compounded in the polymer system of a particular product. Benefits include resistance of product deterioration and discoloration caused by bacteria and fungi, as well as growth of color-causing bacteria, fungi, molds, and mildew. Please keep in mind that even with an antimicrobial agent within the fabric it is extremely important that you keep the product dry. Clean it periodically to keep it free of dirt or debris.

There is water leaking through the seams on my canopy top?

Once any fabric is sewn, subsequent needle holes and seams will affect its water repellency. Dowco recommends applying two coats of seam sealer, such as Kenyon® Seam Sealer 3, to all inside seams, needle holes, and fabric joints prior to use or storage.

Care & Cleaning

Proper maintenance of ClimaShield® Plus and NauticShield fabric is important to help maximize the life of your product. Routine care is simple and certain procedures are recommended.

  • Keep dirt, leaves, and other debris from accumulating on the fabric surface.
  • Washing down with a garden hose on a bright, sunny day is recommended about once a month.
  • To remove dirt from either side of the material, use a soft brush and mild soap (such as Ivory).
  • DO NOT use bleach. Rinse thoroughly with clear water and let dry completely before storing or rolling.
  • If accidental tears occur repair them as soon as possible.
  • Prevent sharp objects, solvents, and hot items from coming into contact with the product.
  • Avoid cleaning in commercial car wash.
  • Do not steam or pressure-wash.


Keep trailerable boat covers secure while trailering. Please note that pontoon mooring covers, enclosures, boat tops, and components are NOT TRAILERABLE.

  • If stored outdoors, do not allow snow, ice, or water to accumulate as this may damage the cover.
  • Do not store or roll up while wet. Be sure product is clean & dry before storage as mildew can grow during storage if moisture is present.
  • To extend the life of your enclosure or top it is recommended that the product be rolled rather than folded prior to storage.
  • Additional storage notes for components with vinyl windows:
    • Vinyl windows and/or flaps should be in the down position for storage.
    • Do not crease or fold the vinyl windows.
    • Avoid contact between the clear vinyl windows while rolling for storage. During periods of high humidity a temporary bonding may occur. Separation may be difficult and could result in permanent damage to the cover.

Am I receiving the exact custom fit cover for my boat?

Yes, every one of our covers is designed to fit a unique make and model of boat, they are not intended to fit a range of boats, they are designed to fit one specific boat. This is why it is critical to be sure you know the accurate make, model, model year information of your boat that you’re ordering product for.

Will my cover hold up in the elements?

Dowco takes great pride in the materials we choose to use in the production of our products, and have invested time and resources in developing our very own proprietary fabrics that we use in the production of each one of our products.

Is my cover intended to trailered?

Not all covers are intended to be used while trailering; you will want to pay close attention to whether the cover is a mooring cover, or a trailerable boat cover. If your cover is intended for trailering, pay close attention to your usage while traveling. Covers are subjected to the most amount of potential damage while being trailered.
