M_Boats: M15 Sail Info

Monty Pals Was out sailing today in steady 14-16K winds topping out @ 20K was able to sail without a reef and maintain boat on her 15 deg. line. I am wondering if I am under canvassed. Can someone direct me to where I can find Main and Working Jib dimensions? I noticed that I still have about 24" of host left on the Main. My boom is sitting just below the mast gate held there by a stop. It appears that I could have the boom above the gate with stop preventing it from coming down. Where should the Boom normally ride on a M15? I have my Jib foot at the same height as the Boom is that correct?
