We run 1 dedicated speed boat with 150hp Yamaha engine.

All dive trips start at 9.30 (9.00 am at the dive center). Dives are held between Estoril  (where we have the dive center), and Cabo Raso.  Most of the trips takes approximately between 15-30mins boat ride. Our dives are mainly reefs, with depths that vary from 6 to 30 meters, depending on the water conditions, and of course your level of certification.

We do usually 2 / 3 dives a day. First dive takes place at 9.30am, and we always come back tp the center for the second dive (see bellow for exceptions). Second dive takes place at 11.30am. Most of the activities takes around 2/2.30 hours in average (including the boat ride) Tea or water is served on the boat (bring your own Cup or Bottle! We are an environmental conscious dive center)

Yes, we have a team of experienced Instructors and always run at a maximum ratio of 4:1 for dives, should you wish to reduce this ratio we can offer the possibility to hire a private guide for an additional fee of €50, per dive.
