Kayak Rig: Work in Progress

The idea of drilling a hole in the deck to insert the mast is not an option for me. I prefer decks to be as water tight as possible. So the idea is to erect a frame on the hull so the mast can be set into it and left there while kayaking. Since the sail will be hoisted to the mast, it is the sail which will be taken down leaving the mast erect. I started by using the remnants of my previous attempts of a frame. This wooden construction I used for the inflatable kayak but found it too heavy, but it is sturdy enough for the plastic kayak. I screwed the longer panel onto the top of the frame thus creating a 'box' like construction with a hole cut for the mast to go into and a wooden base with a hole drilled to insert the bottom of the mast. The longer top section can be cut to size or left its length to use as 'spreders' if rope stays are to be added to keep the tension of the mast.
Now to choose where to fix the frame and in what position?
I positioned the frame at cross-section to the kayak. Resting above the compass well did give it a balanced secure position.
But with heeling I would have to make the base more secure than only bunji straps.

The next position I tried was to place the frame lengthwise to the kayak hull. This would give stability while Running with the wind, but it was not stable if the wind was beam on.
By placing strips of wood underneath the frame it gave a stronger and sturdier foundation the frame to rest upon the hull. The lengths could by cut to size later flush with the deck. Foam or rubber could be placed underneath these cross-sections to make it plush with the hull to stop the frame from moving.
The next position I tried was similar to the first with the frame at a cross-section to the hull but this time I added a 'V' shaped construction to strengthen the stability when on a Run. This position gave full contact with the hull and added to the strength of the frame.
This is the one I will probably use..but it is early days yet.
