Maintenance Information 


In cooperation with MWR, NPSC performs a majority of the maintenance work on the boats used by the NPSC Sailing club. A successful all-volunteer maintenance team helps keep our expenses low and therefor our rental fees low.
Sailing is not like renting a car. If a car breaks down, you can simply pull to the side of the road and call AAA. If sailing, as skipper you are responsible for the well-being of the crew and the boat, and help could be hours away depending on location and weather. Knowing your boat well and being able to perform basic maintenance tasks helps to safely secure the boat and get her home safely.
All NPSC club members are welcomed and encouraged to participate in maintenance activities and learn the in/outs of boat maintenance that is quite a bit different than auto maintenance. Many find the work in maintaining a sailing craft and seeing the fruits of their labor part of the FUN of sailing.  Bottom line, helping out with maintenance not only gives you a better boat, it makes you a better skipper.  
If you are interested in participating in maintenance activities, sign up for the Maintenance forum, talk to any of the Boat Captains or other maintenance team members, or contact the Maintenance Commodore.

Maintenance Boat Captains

NPSC uses a Maintenance Boat Captain system where one club member takes single POC responsibility for a specific boat, or type of boat.  This system helps coordinate maintenance activities for each boat.  Responsibilities include checking on the designated boat(s) regularly, and keeping the Maintenance Commodore and skippers aware of maintenance issues with the boat, and ensuring that schedule preventive maintenance occurs as needed.  (BC's are NOT expected to do all the maintenance on their boat themselves, just facilitate, expedite, coordinate, communicate.)   If you are interested in volunteering as a Boat Captain please contact the Commodore.
