Question about tinker tramp

[lilianroyle]

Just bought one second hand. You inflate the dinghy in the usual way ( four valves for inner and outer tubes) but at the stern are two bicycle type valves. Can someone tell me what they are for.

For 2xCO2 cylinders to speed inflate the rear inner tubes if in liferaft mode. Ours had the cylinders, but local gas supplier took one look and condemned them-aluminum, and badly corroded in prev. owners lockers

Likely to be for connection to the (missing) gas cylinders to auto-inflate as a liferaft. Not present on the standard Tinker.
