From their website:
SRA is pleased to offer youth sculling camps to children ages 9-13. These camps include 15 hours of instruction both on and off the water. The goal of the camps is to introduce the sport of rowing, in particular “sculling” (rowing with 2 oars) in a fun camp-style atmosphere. These camps are limited to 10 athletes at a time in order to provide individual attention. The athletes progress from “coxed quads” (4 rowers and a coxswain) to doubles, and recreational singles and finally racing singles.
