2018 R/V Preservation Work Weekends

The summer project season is fast approaching!  We could really use your help in preparing our research vessel, the R/V Preservation, for an exciting season of fun and interesting projects. We are working on some still-in-progress items and include a number of improvements for the new season. Please review the To Do List and Dream List to see if there is anything that you could help with. We invite you to join with us and get to know our boat and some people in the GLSPS. We'd love to share a weekend of boat work and camaraderie.  With the R/V Preservation and Phil's camper, we can usually house up to a dozen volunteers at a time!


This event is split into separate activities for each day of each weekend. Please register for each day you are able to attend so we can plan tasks and sleeping arrangements based on the skillsets and headcount of those attending each day.

Task Status

The task list below will be updated each work weekend (hopefully each day of work). Task progress will be reported in blue font and completed tasks will be marked (Done!) .
