• As the picture shows, extensions come in several diameters, sizes, materials and collors.  Here is what I consider before buying:

    • RDM or SDM (make sure it fits your mast)
    • Alu or carbon (carbon: less weight / more $)
    • Max AND Min** length

    Here are two extensions that meet my expectations:

  • * RDM = reduced diameter. Often a bit more expensive but les material means less weight. I find RDM mast just make the sail feel better. If you are not sure here, why not check check 'Recommended Masts' first

  • **= Is the 0 really the 0? (If the mast doesn't require extension I DON'T want 1 or 2 inch extra useless inches!)
