What makes some overweight is misplaced priorities, and redundant structural steel, such as transverse framing , etc. The steel would be far more useful in plate thickness than in transverse framing with thinner plate to compensate. I have seen a Tahiti ketch with 3,000 lbs of framing , and 1/8th inch hull plate . Without the framing , 3/8th plate would weigh the same and be a lot tougher ,and more corrosion resistant. With only 1/8th plate against such hard points , the framing increases the odds of holing.
Before putting in more steel, one should look for something which is structurally doing the same thing.
