dutch ships in the17th century were rather good. Especially the east-india traders were well build ships. Also I believe the Dutch were the first to somewhat mass produce ships after the invention of the windmill saw. It lead to our dominance on the world market in those times.
Dutch warships seemed to be rather efficient compared to contemporaries (maybe with the exception of British ships?).
Spanish ships never were really good. Too much pomp and circumstances and not enough practicallity.
