This is a boat I had made at a local fishing Village here in the Philippines. The coast was $216 US. It is made of plywood and glides effortlessly over the top of the water. It has extend my diving range at least 10 fold. It used to take me 35 minutes to swim out to the outer reef in front of my home in the Philippines I can now be there in under 10 minutes. It is also nice to have base to fish from that far out.
Notice the wheel? I made a cart so that I can ferry it to and from the China Sea to be stored above the tide line. Without the cart it would require two or three people to carry it back and forth. Since I can't count on help to be present every time I want to go diving (Each Day I am Alive) I developed the cart using two motor cycle wheels welded to an axel on a simple plywood base.
I can transport it back and forth easily by my self. One note it is a bitch to get in and out of the water but doable. It's like doing a chin up and push up at the same time. The outrigger do stabilize the entry and exit quite nicely though.
