Just wanted to share the rest of what I found out about the blinds in case anyone else is interested.
A few places sell the Oceanair product, West Marine, Ahoy Captain
& Defender to name a few.
The biggest question for me was whether the color differences noted for the product referred to the cassette color or the blind color. The color (silver, beige or white) refers to the *cassette* that holds everything, not the pull-down blind.
Defender was great in answering my questions & giving me Oceanair's customer service
number (it's 802-362-5258 in case you want it).
So, it turns out that Defender sold the blinds in the color I want (beige to match the bulkhead) in the size I want (2) for $10 cheaper a set than Ahoy Captain
so I'm going with Defender. Also - no sales tax!
Here are links in case anyone is interested:
Defender: Port Shade
Ahoy Captain: Oceanair PORTshade Portlight Shade at AhoyCaptain.com - Always your best source.
Thanks again for everyone's suggestions & links!
