The school board’s support for wifi on ferries, or any other place of learning, is ironic. Several studies conclude that exposure to wireless (which includes wifi as well as cell phones) interferes with learning and memory: Fragopoulou et al., Pathophysiology 17 (3), 179-187 (2010); Wu et al., ACTA Biophysica Sinica 15, 152-157 (1999); Hao et al, Neurol. Sci. 2012 (Feb. 24). Summaries of these and other studies supporting a link between wireless and adverse bioeffects — increased stress hormones, disrupted immune function, sperm damage, permeability of the blood-brain barrier, and increased cancer rates (to mention just a few) — can be found at www.bioinitiative.org. This website contains over 1800 peer-reviewed studies (pro and con) on wireless. I urge you to read them and judge for yourself whether it is a good idea to subject our children and ourselves to ever-increasing amounts of wireless radiation.
