You obviously have no clue what you are talking about. The pipeline reef has 3 technically 4 stages.
Outer Log Cabins- This wave feathers out of really deep water. If the reef it was breaking was super shallow, it would be a barrel. This is about 20-25ft Deep according to underwater bathymetry models. This wave only breaks on 15-20ft swells and the period has to be over 15 seconds.
3rd Reef- This wave is basically the same as Outer Log Cabins. It is just as Shallow, but the only reason this wave picks up, is because the shoal from ricky point is much deeper creating a refracting effect which picks the wave up higher. This will start to break at around 15-20ft.
2nd Reef- This wave is the first wave of all the pipe reefs that can be paddled. The reason this wave picks up is because after 3rd Reef, the wave shoals out, then mushes. In between 2nd and 3rd Reef the Reef drops from about 15-20ft deep to about 30-40ft deep. When it hits the end of the rocky point shoal, the wave picks up dramatically setting a wave breaking to about 10ft of water. Once the wave reforms, it hits first reef. This wave starts to really break at around 10-12ft.
1st Reef- After the 2nd reef reforms into this reef, the water level drops around 6ft. Thats why pipeline barrels is because of the waves strength over all the reefs, and then it comes out of deepwater and slams on a 4ft reef. People don't seem to understand that the only time you can get hurt by the reef at pipe is on the take off. because if you look right after the take off 10-15 yds down the line, it turns into sand. 1st reef breaks from Flat-10ft.
PIPELINE WILL CLOSE OUT OF ANYTHING THAT IS REALLY BIGGER THAN 15FT.
BEST PIPE SWELL-- 10FT WNW @17SEC, LIGHT TRADE WINDS, MID JANUARY OR FEBRUARY.
