The Mariners at First Presbyterian Church is a Christian social and service organization comprised of both singles and married couples. The Mariners host a fellowship coffee on the third Sunday of each month after worship and then meet that evening at 6:00 PM for a pot-luck meal and planned activities. In the past, these have included informative programs, a fall hayrack ride and cookout, a February "Sweetheart Dinner", "Hanging of the Seaweed" (preparing the church for Advent and Christmas) and other service related projects.
