Your student briefing needs to contain the following elements -
Brief your students to follow you on your starboard side, in front of your wake, leaving a minimum of 3-5 PW lengths between them and the PW infront.. the pattern should look similar to the photo above.
The dangers of following directly behind each other is that if someone was fall from a PW or stop suddenly the PW behind will run straight into them. The reason for keeping your students to starboard is that they are then kept on the right side of any channels and away from other craft.
Move yourself into a more obvious area in direct eyeline with your student (not on a collision course!) so that your student can see you & show the hand-signal again, or just hold you hand up in a stop position.
Stop the session immediately, recall your student & remind them of the initial briefing. Most PWC's have a speed guage onboard - for novice students, tell them a physical speed to follow i.e. 10 knots/mph/kmph - it is very difficult for new riders to know the difference between planing, displacement speed etc.
Stop the session immediately, recall your student & remind them of the initial briefing. You may need to demonstrate the course for them to have a full understanding of what is expected of them (especially with slalom exercises).
Stop the session immediately, gather all of your students together in one group & wait for the craft to pass by. If your students paid attention to your briefing they should already slowed to displacement speed when they saw the other craft heading towards them.
Teaching PWC courses creates an entirely new element to any thoughts you may have previously had on 'group control'. The main reason for this is the fact that you are looking after anything up to 3 PWC's and 6 students at any one time, all of which have the capability of going up to 70mph in opposite directions!
The key is in giving an effective briefing, but we are also going to have a look at the 'worst case scenario' and how you as the instructor can deal with this.
Prior to briefing - Answer the following questions to yourself:
