Those unfamiliar with the capabilities of many adventurous outdoorsmen (and women) facing serious disabilities, may be surprised to hear that this fixture is designed to assist quadriplegics who have limited use of their arms and possibly little, if any, ability to grip with their hands. This fixture also proves especially useful for a paddler that has good use of only one arm and hand!
I put all my designs in the public domain so they can be freely reproduced, even for profit, and noone may patent them to preclude others from fabricating them and perpetuating their use.
Together with my seat adaption, shown in the photos below (and the subject of a future Instructable), this combination has safely brought the freedom, adventure, and inclusion of the wonderful sport of kayaking to hundreds of participants.
The Paddling Fixture is easily constructed with a minimum of parts and a total cost well under $100. The hardest part of the design process is making a few 90-degree bends in the aluminum braces that hold the base of the boom to the deck plate.
The design, as presented in this Instructable, is specifically tailored for use on an Ocean Kayak, Inc. Malibu Two model. The M2 is, to date, the best selling kayak in the world and the model most often found to be available at rental outfitters. This design is Plug & Play to a stock Malibu Two, requiring absolutely no modifications or additions to the kayak.
Modifications to this design for adaption to another kayak model may include one or both of: Changing the Base Plate (white, in the first photo below) in shape and/or method of attachment to the kayak, or changing the length of the Boom (shown as 48 inches in length in this design). The rest of the design would remain unchanged.
The List of Materials is quite small, so I'll simply present them as they are encountered in the build process. With that said, let's get started...
