It is important that your forward energy matches the energy of the oncoming wave to maintain forward momentum, as a wave will pick you up and push you backwards if you stop. This is achieved by limiting the time in which you stop paddling while negotiating a wave or white water. There will be times where you stop and wait instead of paddling into an unsafe position in relation to a breaking wave.
In all cases, the rescue board should be positioned directly into the wave (perpendicular) to minimise resistance.
