About four years ago Blew noticed that wake surfers were switching from traditional wakeboard boats to bigger 40-foot-plus yachts so they could surf in taller more challenging waves.
Boat wave height. To find the height of the waves generated by the boats I used the equation summarized by Sorensen and developed by Bhomik Soong Reichelt and Seddik. If you can sight along several wave tops in a row when in a trough then the waves are about three feet high which is what most of us judge to be six-footers Sight along the gunwale about two feet off the water to judge smaller waves. Speed reduced some pounding at speed.
This equation was produced by measuring the waves produced by 12 different recreation-type vessels. If the crest of the wave is at eye level then its a 7-footer. Remember a wave will have enough potential energy to knock your boat down starting at 30 percent of its length and certainly will be large enough if it is 60 percent of the boats length.
Waves will break when they get too steep to maintain their height. New and used models for sale. Remember pitch and roll will ensure that the boat and your eyes will be at an angle more often than not so you may not get a true measure.
These analyses resulted in estimates of individual wave height and period for each boat wake event. Boat length Wave height Boating conditions. The records of wave height and.
The equation for this depth is the sum of the wind-wave height and the forecasted swell. For example using the minimum 30 percent wave height to boat length if your boat is 40 feet long then the wave-height danger zone starts at waves 12 feet high 40 x 30. Ive found general wake wave databases where wake characteristics are dependent only on hull shape but would like to know if any further research has been carried out - particularly considering ski and wake-boarding boats.
Boat wake characteristics were estimated from the pressure measurements using linear wave theory and standard time-domain analysis techniques. Ad Luxury Cobalt Boats in Lake Geneva WI. A waist-high wave would be about 3 feet and a knee-high wave about a foot and a half.
