Question 1

Is 900D polyester waterproof?

Accepted Answer

900D polyester is highly water-resistant on its own; with a polyurethane (PU) coating and reinforced 3000 PA seams as on Safeboatz covers, it becomes fully waterproof under rain, snow and trailering conditions.

Question 2

How long does the waterproofing typically last?

Accepted Answer

With proper care, the PU waterproof coating on a 900D marine-grade polyester boat cover lasts 3-5 boating seasons. Lifespan depends on UV exposure, washing frequency and storage conditions. Re-treating with a marine fabric sealant every 2 seasons is recommended.

Question 3

Is 1200D better than 900D for boat covers?

Accepted Answer

1200D is slightly more abrasion-resistant but heavier, harder to handle, and slower to dry. 900D offers the best balance of strength, weight, breathability and waterproofing for trailerable boats. For most 17-22 ft boats, 900D is the optimal choice.

Question 4

What hydrostatic rating should a boat cover have?

Accepted Answer

A boat cover should have a hydrostatic rating of at least 1500 PA to be considered waterproof. Premium covers like Safeboatz reach 3000 PA at the seams, enough to withstand heavy rain, melting snow and standing water without leaking through.
