I would be tempted to buy the system if I could demo it first. I would probably get a longer racing board dedicated to this and put the more permanent fastening system. I would make my 14' Tahoe Zephyr go pretty fast while providing a great cross-training exercise. I noticed the rower's hands were crossing over each other. Is this common with sculling?
