    This question relates to steel hull design.

    I have a question about the placement of frame members. Some sources say you should space the frames a small fraction of an inch away from the inside surface of the hull and have the stringers in contact with the hull. Others say to place the frame members in contact with the hull.

    What is best?

    You can engineer the hull either way.

    stick pieces of 1mm mig wire under the vertical framing it helps the look outside.
    If you take care with the weld size, leg, throat, length you can make a pretty fair looking hull
    You can IF you end up BUILD fair, use a cup grinding wheel so that no penetrations show at all
    Cupped wheels are rarely used, peop;le do not really know of them. But with you conventional grind wheel it takes a lot of skill to not gauge

    As gonzo and Dean say you can build it either way. Which way is "best" depends on what the hull is for...exterior appearence for a yacht or interior robustness and longetivity for a fish hold.
