BannerBayMarine FinDelta anchor riding sail. Virtually brand-new. Hardly used. One of the earliest of FinDelta's made by Banner Bay Marine. Retails for $445USD (https://www.bannerbaymarine.com/index.php?l=product_detail&p=25)!
Bought for use on a 45' full keel, traditional sloop, but found it a bit too small as the wind piped-up. Would be perfect for a more modern (as in less windage forward) boat or a smaller traditional boat.
Works beautifully - Veering at anchor reduced to something like 10-15 degrees as opposed to 30-40 degrees.
