Seat and perimeter decking


Rick thinks I need to fill up as much of the void in the cockpit as I can to facilitate bailing. Within-24 (the 24 hour record version of Within) may get splashed a bit and any water coming up and over the gunwales will slosh around in the bottom of the boat. If I build up a deck along the perimeter between the seat and the gunwales, then splashed water should shed back into the lake. The remaining water should run to the low point where I will have a bilge pump.


For the ocean version of Within, since my main entry/exit hatch is at the side near the water level, the cockpit needs to be considered a 'wet-area', and minimizing flooding and facilitating easy bailing is a good idea. So, this built up perimeter deck will also be something that will be required for the ocean boat with the full top deck.


What I am thinking of doing, is filling this side area with expanding foam and covering it will fiberglass. Then later when I start working on the ocean version of Within with the full top deck, I can cut out storage bins and close them with hatches to make them water tight.



I put together the seat rails today - two, 3/4" square stainless tubes that run from flanges bolted to the drive leg bay to flanges bolted the the rear bulkhead. For now, I am going to leave the seat rails bolted in place until I have the function of that seat completely figured out. Then I'll epoxy the rails down the the kayak hull floor and epoxy the bolts and flanges in.


I had planed on securing the seat position on the rails with two spring loaded T-handle pins. The problem is that the T-handle is too long and it rubs against the curved walls of the kayak. Darn! Now I have to search the world again for spring loaded pins that are shorter. Until I find something, I'll just use a bolt and nut to hold the seat brackets onto the rails.


The recumbent seat from PowerOn Cycling pivots to allow for various seat angles. I have not yet figured out how to adjust the seat back yet - I was hoping that it would be obvious once I got the seat and rails installed and functioning. It could be something as simple as a tube that extends from the rear of the seat back to the bulkhead wall. If there was a pivot on the seat back and on the bulkhead wall, then I could slide the seat forward and the seat back would automatically recline - all the way down to lying flat on the floor.


I am also thinking of an easy way to link a steering arm up to the rudder in the back. The rudder tube slides into the rudder shell tube from under the boat. It is secured with a rod end swivel bearing at the top. The collar will have an arm welded to it that drops down to the deck at a slight angle. I can hook an aluminum tube up to the arm with a ball joint and run the tube to the right or left hand side of the seat where it would connect to a handle - push forward and steer right, back and steer left.
