Here is a description from Scott Cassell:
Originally built by George Kittredge in 1974, it was upgraded in 2006, 2013, 2023 and is currently located in Osprey, Florida, USA.
Her 24VDC and 12VDC need to be re-wired due to salt-intrusion but the base wiring is in place to use as a template if you wish to wire her the same way we did. The salt intrusion was only once and it happened last year during a long-ocean tow and a storm hit us and the dome hatch was cracked open. The huge waves delivered water into the hull 4 inches deep getting ALL the wiring wet. Now electrical shorts are starting to happen and up to 85% of the wiring needs to be replaced. Also, the exterior DSP&L wiring for the four LED lights are UV rotted and need to be spliced.
Her dome ring / hatch needs a new "O" ring and the four ballast solenoids need to be installed (12V system) to the already existing interior 12V buttons. The thruster batteries still work well but need replacing soon (Nellis Engineering in California is manuf).
The thrusters, batteries and lights are all included along with chargers, oxygen whips and other support equipment. She could be easily diving with just 20 hours work and she includes most everything you will need.
