I would like to share some mods I am currently installing in the space behind the cockpit seat backs (SB).
(1) A storage area between the aft cabin BH and SB frame 1. Access to this area will be from inside the cabin via an opening in the aft cabin BH. SB frame 1 was altered to a solid wall, and I added a transom bung at the very bottom in the unlikely event it has to be drained. This mod does however remove some of the foam buoyancy volume.
(2) I added additional cleats to the SB frames and an extra vertical cleat between SB frame 1 and SB frame 2 to provide additional support for the seat back.
(3) I added additional reinforcing blocks to the seat top aft of the cabin BH for additional deck hardware.
(4) I didn't want exposed electrical wiring in the cabin area for the following things:
Cabin lights, Nav lights, DC outlets, GPS/Fish Finder power and transducer lead.
So, after considerable thought I decided to run all this wiring through separate lengths of 25mm electrical conduit. Wiring will leave the electrical panel and travel under the cabin floor to the lazarette area. It will then go up through the cabin floor via a small length of conduit which is raised higher than the cockpit floor to prevent water entering the lazarette area from the aft storage area. Then it will feed into another length of conduit that travels from the aft storage area to the new forward storage area via the foam filled buoyancy chambers. This conduit is sealed to ensure watertight buoyancy chambers.
I now have electrical access to the aft cabin BH and the seat back storage areas. I also intend to run the stern nav light wiring (Stern Nav light to be located on the boom gallows) up through the lazarette into the stainless-steel gallows pole and out through the gallows to the stern light.
I have covered some of these mods in my blog, it is still a work in progress.
Check out the blog.
Cheers Terry from down under.
