I have a Tayana 42 aft
cockpit. On mine the propane locker is in the
cockpit on the starboard side closest to the
companionway, enclosing the entire width of the cockpit bench all the way out to the
hull. It has two drains...one inboard and the other
outboard in the floor of the locker. They each have a drain hose and they "T" into one through
hull fitting above the waterline. They should drain whether on a port or starboard tack. I don't know the set up on the
center cockpit model. Try Wilson Chang at the TaYang shipyard ...wilsonchang421@gmail.com...He has been very helpful and his
English is okay.
