    Has anyone built stabiliser for the ama? This would be to have a central pivot axa joint like a bearing to allow the ama to slightly “flip flop” up and down the waves. I would have stoppers so restrict movement too much. Or have shock absorption small springs.
    Also, thinking of using aluminium 32mm with 5mm wall thickness axa that is retractable for total boat beam of 1900 at small size to 4000 for widest beam from ama to ama. Powered with 4hp outboard.

    To answer your question, if I’m understanding it correctly, yes.

    Here is a well known example:

    I believe the drawings of the design can be found in the Multihull Design thread.
