At Boishaai we participate in the Boland tennis league. This consists of playing against schools from Hermanus, Strand, Somerset West, Paarl and Wellington. Our teams consist of four senior and two u/14 teams. League starts in September and runs through to March the following year. We aslo compete in the Eight National School's tennis tournaments playing against all the top tennis schools in South Africa. That means our players are competing against the top players in the country on senior as well as junior level.

Boishaai has over the years produced many provincial and national players.
