Your definitive guide to choosing and installing the right covers, halyards, and sheets for your sailboat — and finding the perfect match at MAURIPRO
Mainsail Covers by Boat
A mainsail cover (sometimes called a boom cover or sail cover) is not just a canvas accessory — it’s a crucial protector of your sail’s largest surface when it’s stowed. The right cover shields your mainsail from harmful UV rays, salt spray, dirt, and other wear risks that degrade performance over time.
At MAURIPRO, our “Mainsail Covers by Boat” collection is curated to match specific boat models, rig dimensions, and sail plans. By choosing a cover tailored to your vessel, you ensure better fit, less chafe, and more longevity.
Why a Custom-Fit Cover Matters
- Precise fit: A cover shaped for your rig reduces gaps and flapping, protecting edges and seams.
- Chafe resistance: Well-reinforced cutouts (for topping lifts, lazy jacks, fasteners) prevent wear on the fabric and sail. Many quality covers add reinforcement at cutouts to avoid chafing.
- Material choice: High-grade marine fabrics (Sunbrella™ or UV-stabilized acrylics) resist fading, mildew, and stretch.
- Ventilation and drainage: Good designs incorporate vents or mesh panels to allow moisture to escape and airflow to prevent mildew.
- Ease of use: Features like zippers, Velcro closures, bungee ties, or flaps make donning and removing the cover more efficient.
Tips for Selecting & Using a Mainsail Cover
- Use the precise boat model (or rig specs) when selecting your cover in our catalog.
- Check cutouts for fittings like lazy jacks, topping lifts, or battens — your cover needs to accommodate them without interfering.
- Ensure enough overlap to wrap securely under the boom or use tie-downs to avoid wind lift.
- Inspect stitching, attachment points, and fabric yearly — UV damage and wear often begin at stress points.
- If your boat or sail plan changes, replacing or re-measuring your cover is worthwhile — a misfit cover is worse than none.
Halyards & Sheets by Boat
Running rigging — specifically halyards and sheets — are the arteries of your sail control system. Choosing the right lines and maintaining them properly is essential both for safety and performance. MauriPro’s “Halyards & Sheets by Boat” collection helps you select lines tailored for your vessel’s rigging needs.
Understanding Halyards vs. Sheets
While they may seem similar, **halyards** and **sheets** serve distinct roles on a sailing vessel:
- Halyard: the line used to hoist or lower a sail. It bears high loads, and low stretch is vital to maintain sail shape.
- Sheet: the line used to trim or adjust the sail’s angle to the wind. It needs flexibility, control, and some durability against abrasion.
Confusing one for the other at the wrong moment can compromise handling, especially in tight or windy conditions.
Maintain Your Running Rigging
Proper maintenance significantly extends the life of halyards and sheets:
- Inspect regularly for abrasion, sheathing cuts, or stiffness.
- Rinse with fresh water to remove salt, grime, and grit.
- Lubricate or treat with appropriate line lubricant to reduce friction over sheaves or blocks.
- Retire any line with visible damage to the core or compromised sheath immediately.
- Organize by color-coding or labeling — that helps crew quickly identify halyards/sheets in tight situations.
