The Catalina S63 is a 63 cu ft aluminium scuba tank (9 L water capacity, sold in the UAE as the 10 L size), rated to 207 bar (3000 psi) and finished in sanded bare aluminium with no paint. At 55 cm long and 12.2 kg it is a shorter, lighter cylinder that suits smaller divers, teens and instructors running pool sessions, and divers who want an easy tank to carry on shore dives.
It works well for the warm, shallow reef dives of Fujairah, Dibba and Musandam, where you rarely need the gas of a full 80. Aluminium does not rust like steel: it forms a protective oxide layer, and the bare finish has no paint to chip in salt water. Amit, the UAE Catalina distributor, supplies its Catalina tanks with the convertible Pro valve for yoke or DIN regulators.

Frequently Asked Questions
Is the Catalina S63 a good tank for smaller divers?▼
Yes. At 55.1 cm long and 12.2 kg it is shorter and lighter than a standard 80 cu ft tank, which makes it easier for smaller divers, teens and pool training.
Why is it called a 10L tank when the water capacity is 9 L?▼
Catalina rates the S63 at 63 cu ft of gas from a 9 L water capacity. In the UAE this size is sold as the 10 L tank.
How should I weight myself with this tank?▼
It is 1.27 kg negative when full and 0.82 kg positive when empty, so check your weighting for the end of the dive, not the start.
