Surf ski and double ski rules
Single skis start afloat in knee-deep water, paddle around two orange turning buoys 250 m out and an apex buoy, and finish when the ski crosses the line with its paddler (§4.4.2). The double ski course is the same with the apex buoy further out (§4.4.3). If the surf makes a fair start or finish impossible, the race goes to a dry start or finish on the sand.
Course
Two orange turning buoys about 75 m apart and 250 m from knee-deep water, with an apex buoy about 50 m further out for single skis and about 100 m for double skis (§4.4.2–4.4.3). The summary sheets put the apex at 300 m (single) and 350 m (double) (Section 4, Appendix B).
Start and finish
Skis line up about 1.5 m apart in knee-deep water, and no one may sit in their ski before the start (§4.4.1). The finish is when any part of the ski crosses the line with the paddler riding, holding or carrying it, and you must have your ski and paddle (§4.4.2). You can fall off and remount.
Dry start: paddlers stand with their skis on the beach and carry them in on the signal. Dry finish: after the last buoy you run up to a line about 15 m up the beach, judged on the chest (§4.4.2).
Double ski
Both paddlers must cross the line in contact with the ski and at least one paddle (§4.4.3). At the SA championships the double ski is a combined-junior and a senior event (§11.4.1); in masters the younger paddler's age sets the band (§3.8.2c).
Ski relay
Three paddlers each complete the course, leave the ski at the water's edge and run around the turning flags to tag the next (§4.4.7).
Common disqualifications
Deliberately impeding another ski, ignoring the Starter's alignment instructions, two skis with the same number (the wrong user is disqualified), and a ski without the LSA compliance decal (§4.4.1–4.4.3).
Common questions
How far out are the surf ski buoys?
The turning buoys are about 250 m from knee-deep water, with an apex buoy further out (LSA Competition Manual §4.4.2).
Can you fall off your ski and keep racing?
Yes. You may lose your ski and remount, but you must finish with your ski and paddle (§4.4.2).
What is a dry start in surf ski?
When the surf makes a fair water start impossible, paddlers line up on the beach and carry their skis in on the signal (§4.4.2).
Which age group does a masters double ski race in?
The age group of the younger paddler (§3.8.2c).
How many paddlers are in a ski relay?
Three (§4.4.7).
