Comments about Hatch - Ocean 30 Flange Base by Lewmar | Plumbing & Ventilation at West Marine
The product itself is what I expected. The dimensions are accurate and it fit my boat as expected. No leaks and the quality is above average. Makes my 1986 sailboat look more modern. A comment regarding the service. I ordered the hatch and selecting free shipping, quoted 3-5 business days. I received the package in 2 days, however to my dismay it was the incorrect sized hatch and the hatch itself was damaged due to the poor packaging. That being said, the customer service at west marine filed my claim promptly and resent a new hatch the same day and I still received the correct, undamaged (much better packaging this time) hatch within the original quoted shipping timeframe. Overall, great product. Thankful that west marine stood by their service and fixed the issue. I'll be returning as a customer service for that reason.
