I use an inflatable standup paddleboard to follow novice rowers.  It uses a 5hp outboard motor because sculling boats move pretty fast and paddling a standup paddleboard is pretty slow.  Being inflatable makes sure that I do not injure a rower should I run into them.  It allows me to be very close to them as well.  AND since it is inflatable I can take it anywhere my client’s need me to be.  Here is more info on this unique water vessel:
