Frequently Asked Questions
What mil thickness do I need for a boat cover?
For seasonal boat covers, 12–20 mil is adequate for most small to medium boats. Choose 14–20 mil for a good balance of protection and manageability; 30 mil vinyl provides extra puncture resistance for heavy-duty or long-term outdoor exposure.
Should I choose clear vinyl or opaque polyethylene for my boat?
Choose clear vinyl if you need visibility and light transmission (for sheltered cockpits or temporary shelters). Opaque polyethylene is typically lighter, more affordable and better for complete UV protection and hiding stored gear.
How should I secure a tarp to a boat to prevent tearing?
Use reinforced grommet points and a combination of straps, bungee cords or marine-grade rope tied to fixed points. Space tie-downs evenly, avoid concentrating stress on one grommet, and add edge protection (soft pads or corner guards) to reduce chafe and tearing in wind.
