After you beat Norman in Sapphire, head next door (the house to the left of the gym). There, Wally's parents will give you HM03 (Surf).
after you beat flannery you go back to where your dads gym is and beat that gym hope it helped :p
To defeat or "beat" the 7th gym leader in Pokemon sapphire there twins and they have a solrock and a lunatone to beat them I suggest about level 40-50 water types.
The gym leader in the normal gym, your character's father will give it to you after you beat him.
go back to your fathers gym and defeat him
You must beat the MossDeep City gym to use the HM for Dive.
Beat the E4 and Champion.
beat the fifth gym, talk to Wally's dad in the house next to the gym
