Officiating Game where One Team is Deaf

[NICK]

Having refereed at the Deaf Olympics a few years back, couple of things:
1) we had to use whistles with peas so that the players could feel the vibrations. Fox forty whistles were useless in these games.
2) some patience, as sometimes play tends to go on after the whistle has gone off.
3) sometimes we had to go on court to seperate players playing too physically especially on the low post area.
cheers and have fun- Nick
