    metal versus composites. Which is best for building?

    Hi Guys:

    I am looking into building an offshore CC fishing boat 27 - 30 foot. What is the best route, metal or composite and what are the advantages or disadvantages of each?

    Are you building a one off metal is the way to go because it's easier.

    Unless your making a high speed hull composites is not really neaded.

    If you are making a series off boats with the same specs composites is behter.

    Metals like steel has alot off advantages, it's easy to cut out a pice and just weld in a new. If you hitt something you will get a bump and not a hole.
    If you want to scrap the boat you can just sell it as junk steel and get a few dollar per tonn and it will be cutt up and melted for diferent purposes while composites can not be resycled easely(not that I know off)

    Composites is light compared to strenght and it's easy to cast a boat if you have a mold and it's more efficiant to make in composites if you plan to make more than just one.

    My thoughs.

    G'day Tallow

    The British (bless their little hearts) have a competition called conkers.

    The are nuts (not the British, then who am I trying to kid)

    To decide the winner they whack their nuts together (the conker nuts) and the winner is the one that survives.

    Composite or steel. Put them on a collision course.

    Then pick the winner.

    Seen composite hit reef at speed, grind over it and keep sailing with minimal damage . (my last boat)

    Seen steel hit reef and sink. (a mates boat)
