The Zodiac is my favorite dive boat. They are relatively inexpensive, portable, can haul a ton of gear (1800 lbs for the futura mark IIc), and are easy to dive with.
I've put up a few pictures of the boats here of the boats in action. Enjoy!
A high school friend of mine gave me this boat. It was sitting in garage for several years and needed a new home. When I first saw the boat and set it up, I was surprised how good it looked. However, about 20 minutes into the maiden voyage, the adhevsive holding the transom weakened and the transsom started to separate from the pontoon! We came pretty close to losing the transom and the engine.
Above you can see the classic Zodiac out diving at Lake Owen. In the land picture you can see my Zodiac on top of the Avon. This is how we carried both boats from the Cabin to the lake.
The local Zodiac shop gave me an estimate of approximately $1500 to $2000 to make all the necessary repairs. Since a brand new Zodiac is only about $800 more than that, I decided to repair the boat myself. One of my friends said "You can buy a lot of glue for $1500". Very true. So, many nights were spent working on this boat and getting it seaworthy again and it returned to the water for a trip to Lake Owen and later on a trip to Green Lake. Unfortunately, the boat still had some serious leaks and was usually half full of water whenever we returned from a dive. The next set up repairs will involve sealing up the floor or maybe re-gluing the entire floor
Note the non-conical pontoon ends in the 2004 and later Futuras. Also, you can see the speed tubes in the hull diagram.
