YimSting 1200D Boat Cover 16–18.5 ft
The YimSting model uses a thick 1200D marine grade polyester with ripstop construction. It features a backside 3-layer PU coating and waterproof sealing tape at seams. Reinforced points at bow and stern reduce tearing, while robust windproof straps help secure the cover during travel. Best for boat owners who want strong protection without frequent strap maintenance. Note a potential limitation: very strong winds still require secure tie-downs to avoid movement.
HAHASOLE 1200D PU Boat Cover 17–19 ft
This cover emphasizes all-around protection with double stitching and 4-layer fabric: waterproof coating, 1200D Oxford, anti-UV, and PU. It includes 12 quick-release buckles and an elastic bottom hem for a tight fit. Best for boaters who storage for long periods and want strong UV and water resistance. Better for those who trailer often, though the higher fabric density can be a bit heavier to handle.
YimSting 1200D Boat Cover 17–19 ft
This variant mirrors the 16–18.5 ft model with reinforced seams, triple fold and double stitch construction, and edge protection at key wear points. It offers windproof straps with removable components and a tight bottom elastic cord. Best for boaters who need a longer cover for storage or extended trips. Choose this if your boat sits outdoors for months and you require durable UV resistance and tear resistance.
Mancro 17–19 ft Trailerable Boat Cover
Mancro’s cover uses heavy-duty Oxford fabric with waterproof and UV-resistant coating. It offers 11 adjustable straps with quick-release buckles for a snug fit and is marketed for both long-term storage and travel. Best for budget-conscious buyers who still want reliable all-season protection. Limitation: may require more frequent checks on strap tension during long trips to ensure a secure fit.
iCOVER Trailerable Boat Cover 16–18.5 ft
iCOVER offers a universal fit for boats up to 16–18.5 ft with a 94″ beam. It features a heavy-duty elastic hem, buckle, and strap tightening system for quick installation. Best for owners who prioritize a simple, quick setup and a compact storage footprint. Limitation: may understate some wind resistance compared to higher-end 1200D options with extra reinforcement around wear points.
Buying Guide
What should you consider when choosing a heavy duty boat cover?
- Boat size and hull type: Ensure the cover matches your boat’s length and beam. A snug fit prevents water pooling and wind damage.
- Fabric and waterproofing: Look for 1200D Oxford fabric with PU coating and UV protection for long-term outdoor use.
- Seams and reinforcement: Triple-folded seams and reinforced points at bow and stern increase durability in high-wear areas.
- Wind protection: Detachable or fixed straps with buckles reduce cover movement during travel.
- Storage and maintenance: Removable straps and included storage bags simplify transport and storage when not in use.
Frequently Asked Questions
- What is the difference between 900D and 1200D boat covers? – 1200D is thicker, generally more durable and tear-resistant, better for long-term outdoor storage and frequent trailering.
- Can a heavy duty cover protect against snow and ice? – Yes, if it has high water resistance and UV protection, but removal of snow buildup is advised to prevent strain on the fabric.
- How important are windproof straps? – Very important. They prevent movement and tearing during highway travel or strong winds.
- Should I choose a 16–18.5 ft cover or a 17–19 ft cover for a 17.5 ft boat? – Choose the one that offers a snug fit around the stern and bow; a slightly larger size can still fit but may be less secure.
- Is storage bag necessary? – It helps protect the cover when not in use and makes transportation easier.
