How to Choose the Right Tarps for RV Awnings & Boat Covers

When you’re choosing a tarp specifically for RV awnings or covering boats, think about three priorities: fit, material/thickness and fastening. Fit matters because a tarp that’s sold as a nominal size can be smaller than advertised; look for "finished size" or exact measurements so the tarp will fully cover your awning or hull without constant readjusting. Size choice depends on use—measure your awning length and projection, or measure hull length/beam plus extra for tie-downs and drape.

Material and thickness determine longevity. Virgin polyethylene at 14 mil is a reliable heavy-duty choice for year-round exposure — it stands up to UV and tears better than thin (7 mil) options. Thicker tarps weigh more and are harder to handle but pay off when you need long-term protection. Check weave count and whether the manufacturer states virgin (non-recycled) polyethylene—those are less prone to brittle breakdown.

Fastening and reinforcement are equally important. Marine and RV use involve wind, chafe and repeated tie-downs; look for reinforced edges, metal (preferably stainless) grommets spaced every 24 inches or closer, and welded seams or double-stitched hems. Grommet spacing affects how securely you can anchor a cover—36-inch spacing on lighter tarps often requires adding webbing or extra tie points for reliable hold in wind. Color and finish have a role too: reflective whites reduce heat buildup under covers, while silver/black or green blends offer UV reflectivity and aesthetic blending with campsites or marinas.

Customer feedback often highlights build quality, ease of installation and value for money. Expect some debate: heavier tarps cost more but provide better durability; some buyers experience edge wear or tear after prolonged exposure, so plan to check tension regularly and use additional reinforcement where hardware contacts sharp surfaces. For boaters, saltwater exposure calls for rinsing covers and using stainless hardware to reduce corrosion. For RV owners, consider breathable fit or occasional ventilation to avoid trapped moisture under covers.

Budget Tiers

Budget: Thin or light-weight tarps (typically 7 mil) are cheap and good for short-term or seasonal protection. Expect lower puncture resistance and wider grommet spacing. Mid-Range: If available, these balance weight, durability and price—better weave and closer grommets. Premium: 14-mil virgin polyethylene with reinforced edges and close (24 in) grommet spacing—best for long-term storage, frequent travel and harsher climates. Choose based on how long you expect a tarp to be deployed and how much handling it will endure.
