Penrhyn Mawr Tidal Race - (Inner, Middle and Outer Race - increasingly faster and larger waves) famous among sea kayakers, advanced paddling (at least when it looks like these videos) multi-directional waves, can be very technical and challenging (more
tidal races). Obviously (from the videos) some skilled sea kayakers with bombproof rolls can handle the race in severe conditions. We do not currently (2020) have reports yet of paddle runs and conditions that safely favor various skill levels (if any) of surfskiers. This may be a tidal race that is simply too full of counter currents, intersecting waves, whirlpools, etc. to allow many if any surfskiers to thrive on its waves. In other tidal races such as
Deception Pass, surfskiers have already spent significant time learning angles of entry and exit, zones for surfing without excess turbulence, and weather and tide condition sets that are likely to favor their skill levels.
