1. The Marketplace Forums can be useful for members who know one another well from forum discussions and offline communications and wish to post boatbuilding tools, drafting tools, molds and tooling, and other professional equipment for sale or trade. However, caution and good judgement should always be used. Especially when considering any business with anyone not already well known to you and trusted, due diligence must be used to confirm details and identity and be sure the transaction is safe before any money or property changes hands. Always use good judgement and perform due dilligence and follow these guidelines.

    This is to advise anyone interested that the kFOIL patent is actively for sale. This patent was granted May 3rd, 2005 ; Patent Number 6,886,481 B1 kFOIL™ is filed in the US only.
    The patent covers a retractable, pivoting foil located inside of or on the bottom of a canting keel bulb. The foil is deployed upwind to add lateral resistance lost when the keel cants. It works in place of extra foils such as daggerboards or a forward rudder and allows for increased inside room, increased safety and lower wetted surface than most other solutions for canting keels.
    Here are a couple of pictures of the foil system as shown on SA:
