Question is about the rules of blocking the ball in beach volleyball and its differences from indoor.
Is there any other block differences from indoor volleyball other than counting as one of three possible touches?
Is there any more differences from indoor volleyball other than that its counted as one of three possible touches?
No. Other than the unavoidable differences due to the number of players (and the existence of the libero in indoor volleyball), Rule 14 "Block" is identical between the indoor and beach apart from 14.4.1:
14.4.1 A block contact is not counted as a team hit. Consequently, after a block contact, a team is entitled to three hits to return the ball.
14.4.1 A blocking contact is counted as a team hit. The blocking team will have only two more hits after a blocking contact.
(my emphasis in both cases).
