    I’m currently building 28 foot aluminum v hull and my metal suppliers center keel extrusions are on back order until September. Does anyone know another metal company that carry one? I have been searching and searching and keep striking out.

    Couple different versions it looks like, don't know which one your looking for. I'll say this, we use a specific extrusion that's essentially an alloy d guard. Last delivery was similar lead time as you had quoted (about 6 months) but they pulled it off a few weeks earlier.

    I wouldn't recommend using an extrusion below the waterline, especially if it is structural.

    What shape and what alloy do you use?
