It is a good laugh (if wet, cold and wobbly is you thing) but, unless you are reasonably close to Pompey, it is a short day. You get the same package as regular recruits. Briefing, training, getting wet (about 45 mins in the training rig) getting dry, debriefing in about 2 hrs. The instructors are a mix of civvy and Navy and are a great bunch. Recommended.
