Stay out of the way as best you can. The past-time is called surfing, not paddling. Paddle completely around the break if necessary and stay out of the impact zone as much as possible. As long as the surfer riding did not intentionally run the paddler over, it's always the paddler's fault in any collision. An apology is all that's necessary to settle a dispute.
Boards get dinged and broken, that's part of surfing.
No financial remuneration should ever be asked for and none given. Surfers with no leash have priority over those with leashes, regardless of wave position. This priority increases with the degree of difficulty that riding the break leashless presents. Unquestionably advanced surfers should have priority for the most challenging waves. However, it is the responsibility of the advanced surfers to share and give lesser challenging waves to the lesser ability surfers who observe this rule.
