RS Mast Floatation Bag
Inc. Tax
Ex. Tax


A twin tube mast Flotationbag. It slides up and down the mast at the same time as the mainsail, which makes it a very tidy and unobtrusive design. Helps prevent a full inversion. Total capacity 8 liters. Only works on boats with a mainsail mast track. This is a generic fitting - can be adapted to work with many RS models with a mast track and mainsail bolt rope. Does not include boat specific instructions; we recommend connecting the two fabric loops at the top of the bag into the main halyard line (when connecting it to the grommet at the head of the sail). A small diameter mouse halyard can be used on the lower end to ensure you can pull the sail back down without the bag getting stuck in the track.

  • RS Part Number RSM-SP-900
  • 8 Liter Capacity
