Buying Guide for Trailer Accessories and Covers for 18 Foot Boats
Choosing the right trailer accessories and covers depends on several factors related to your boat size, environmental conditions, and trailer setup.
Bunk Carpet Considerations
- Thickness and Material: Thickness between 5mm and 12mm is ideal for cushioning your hull. Marine-grade polyester or carpet ensures durability and UV resistance.
- Size Compatibility: Measure trailer bunks accurately to select carpet width and length that fully envelops bunks without excess waste.
- Installation: Look for pliable carpets with suitable backing for easy stapling or glue adhesion to secure them firmly on the bunks.
Brake Hose Selection
- Certification: Ensure the hose is DOT certified to meet safety requirements for trailer braking systems.
- Material and Fittings: Stainless steel flared ends with brass fittings offer corrosion resistance and a reliable, leak-proof connection.
- Length and Flexibility: Select a hose length compatible with your trailer and sufficient flexibility to facilitate installation and movement.
Boat Covers
- Material Quality: Heavy-duty polyester with PU and anti-UV coatings ensures waterproofing and sun protection for extended outdoor storage.
- Fit and Securement: Adjustable straps, elastic hems, and buckles provide a tight, windproof fit that protects against harsh weather and prevents cover blow-off.
- Ventilation: Adequate air vents reduce moisture buildup to avoid mold and mildew, preserving your boat’s surface.
Additional Accessories
- Guide-Ons: Adjustable guide-ons made with rustproof materials improve boat loading accuracy and protect trailer sides.
- Durability: Prioritize corrosion-resistant finishes and marine-grade construction for longevity in harsh environments.
