Removable suction cup fin
First Claim
1. A removable fin assembly for mounting to the underside of a small watercraft having a centerline comprising:
- at least one suction cup having a cup side and an anti-cup side wherein the cup side can be reversibly attached to the underside of said small watercraft;
at least one distributor member having a fin side and a suction side wherein the suction side of at least one distributor member is attached to the anti-cup side of at least one suction cup; and
at least 1 fin member having a port side and a starboard side along a transverse axis wherein at least one fin member is attached to the fin side of at least one distributor member and mounted such that the transverse axis of said fin member is not parallel to the centerline of said small watercraft and said fin member extends downwardly with respect to said small watercraft.

Abstract
A removable fin assembly with at least one suction cup for attaching to a small watercraft and a method for attaching a fin assembly using at least one suction cup to a small watercraft. The fin assembly removably attaches to the underside of a small watercraft with the fin extending downwardly. The fin assembly is made up of at least one suction cup, at least one distributor to spread out the forces across the suction cup or cups, and at least one fin. The fin can be a traditional fin, a hydrofoil keel, or something similar. An optional shell can be added around the attachment location to reduce drag. Recesses can be added to the distributor to help support the fin or reduce drag.

14. A method for attaching a removable fin assembly to the underside of a small watercraft having a centerline comprising:
-
(a) providing a fin assembly comprising at least one suction cup, at least one distributor member, and at least one fin member having a transverse axis; (b) locating the desired attachment location on the underside of said small watercraft; (c) orienting the fin assembly such that the transverse axis of said fin member is not parallel to the centerline of said small watercraft and such that the fin member extends downwardly with respect to said small watercraft; and
,(d) temporarily attaching the fin assembly to the underside of said small watercraft at said desired attachment location with the suction force from at least one suction cup. - View Dependent Claims (15)
