Late May Open Water Course Just Scheduled!

Our next three week SSI Open Water SCUBA Course is scheduled to start on Sunday, May 31 , 2026 with the first class session held from 1pm-4pm at North Atlantic Scuba in Marshfield. The course continues on the next two Sundays, June 7 and 14 with the classroom sessions held at NAS from 1:00pm-3:00pm and then continue with the pool sessions from 4pm-7pm at The Weymouth Club Pool. The four local open water dives that will complete your certification are scheduled for the weekend of June 20 and 21. We also offer a referral to complete these open water dives if you should be traveling.  Deposits are now being accepted at this time with a limited amount of seats available. You can give us a call or stop by to register.

We offer Courses monthly starting in February and continue through September. We do offer Course Gift Certificates that can be applied to any of our Courses. Private instruction is also available.
