Holland America Line will not disclose the buyers behind two very similar ships, but they both hold striking resemblances to a start-up cruise outfit's future vessel.

The Carnival Corp brand on Thursday confirmed plans to sell four of its 15 ships, as previously reported in TradeWinds.

TradeWinds then reported that, among those vessels, Holland America sold the 1,350-berth Veendam (built 1996) and 1,258-berth Maasdam (built 1993) to undisclosed buyers.
