Not really - steel boats easily last 100 years. A friend of mine lives in one from around 1940 and the steel is in fine shape. As long as it's properly maintained there's no problem.
Yet, Modern ships have a lifespan of 25 to 30 years before corrosion, metal fatigue and a lack of parts render them uneconomical to operate.https://en.wikipedia.org/wiki/Ship_breaking
With smaller boats labor is a higher fraction of construction costs vs raw materials. Going big results in massive increases in efficiency which almost paradoxically shift things to a shorter ship lifespan.
