The Wreck Today
The 36m Sub., or J5 Sub. was probably the first of the J Class submarines to be regularly dived. It lies in 36m and has been referred to as the Yellow Submarine, a reference to the yellow zoanthids that decorate a large portion of the hull.
The submarine sits upright on a sandy bottom, and is virtually intact. An interesting dive can be had swimming along the outside, due to the proliferation of marine growth, and the numerous fish present.
Penetration inside the wreck is possible at several points, where large plates were removed from the hull prior to scuttling. However , caution must always be exercised, and octopus regulators, good torches and a reliable buddy are all obvious pre-requisites.
While swimming through the interior of these submarines, one cannot help admiring the courage of the forty-four crewmen, who lived in such confined quarters for extended periods. Due to the limited bottom time at 36m, this submarine cannot be fully explored in the dive. However it represents an exciting and challenging location, to which the experienced diver will want to return , time and time again.

Hazards and Precautions
The same hazards associated with depth and wreck penetration apply to all four of these scuttled submarines outside the Heads.
