Protect Your Investment: Top Tips for Boat Winter Storage & Covers
As the leaves begin to change across Canada, boat owners know it’s time to think about winter storage. Prepping your boat properly now can save you from expensive spring repairs, mold growth, and cracked vinyl windows later. This step-by-step guide covers the essentials — from cleaning and repairs to choosing the right cover — with products trusted by marine pros and DIYers. A printable checklist is at the end.
Step 1: Deep Clean Before Storage
Don’t let dirt, mildew, and salt linger on your boat all winter. Left unchecked, they can break down fabrics, finishes, and vinyl.
Recommended Cleaners for Marine Vinyl
- IMAR #603 Stamoid® Marine Vinyl Cleaner
- IMAR #601 Stamoid® Marine Vinyl Protective Cream
- Iosso® Mold & Mildew Stain Remover
Pro Tip: Use a soft brush for textured vinyl and always rinse thoroughly. Any residue left behind can trap moisture and cause damage.
Step 2: Repair Before It Gets Worse
Small issues become big problems over a Canadian winter. Tackle quick fixes now and note bigger projects for winter downtime.
Quick Repair Tools & Products
- HH-66 Vinyl Cement — Reseal seams or patch small tears in marine vinyl and clear windows.
- Tear-Aid Type A
- Tear-Aid Type B
- Marine Fasteners Collection
Step 3: Protect Clear Vinyl Windows
Clear vinyl windows (Regalite®, Strataglass®, or extruded vinyl) need special care before storage. Cold weather and grime can lead to clouding, scratches, and cracking.
Best Cleaners & Protectants
- Skippers Klear to Sea
- IMAR® Strataglass Protective Cleaner
- IMAR® Strataglass Protective Polish
If your windows are already severely damaged, no cleaner will undo long-term UV or element damage — in that case, replacement is the safest choice.

Step 4: Choose the Right Boat Cover Fabric
