Re: Pros and cons of steel sailboats
Disclaimer- although I briefly went to engineering school I have no detailed knowledge of N.A. or structural engineering and unlike some admit it.
Still seem to recall all metals have thermal expansion and contraction issues. Although of greater degree in Al still operative in Fe. This is one reason framing in metal boats allowed to " float". Also seem to recall allowance for thermal effects is incorporated into design of attached framing such as at watertight bulkheads.
Seem to recall metal around welds and welds asked to handle load cycles generated by thermal effects are more likely to fail.
Also recall t or angle framing cut and welded to allow curve is much stronger than simple framing bent to curve.
Wonder how above issues impact on Brent boats.
