Maybe it is time you got yourself your own red suit, would the guys in your swimming club notice if you turned up for training in red? If the thought of wearing red speedos in front of your mates is too much perhaps you might like a red bikini, 1" sides for use on quiet beaches when no one you know is around.
Then again both 2" red speedos for the pool and 1" red bikini for the beach might just be the solution.
Suspect that you are correct and that it is an underwater hockey logo, though I thought underwater hockey used something like a windscreen scraper to push the puck along with.
Does this help:
