Operators are committing to multi-vessel construction programs, and some yards have begun boats on speculation before securing a buyer. Series construction gives operators common machinery, familiar layouts and more predictable maintenance. The build programs also reflect the financial strengths of consolidated operations with strong credit lines that can afford to build on spec. Their confidence also reflects the confidence of their lenders and backers in the future of this market. For an industry that measures assets in decades, these build programs amount to a practical vote of confidence in the waterways’ future.
