Steel
Very strong, but it rusts and needs constant care
Welded steel is the strongest and most forgiving hull material in a collision or grounding. A welder can repair it in almost any port in the world. The price is weight, and a constant battle against rust, especially on the inside.
Strengths
- Highest impact strength
- Repairable by any welder worldwide
- Relatively cheap to build
Weaknesses
- Rust needs constant attention
- Heavy, so slower in light winds
- Hidden interior corrosion lowers resale value
