 Chapman 's archipelago frigates provided better protection for their crew than the galleys they replaced , and up to three times the capacity for stores and provisions . They could operate in the narrow , shallow waters around skerries in all weathers and in open water in all but the worst storms . They had a deeper draft than galleys , but considerably shallower draft than traditional sailing warships . The new ship types also increased the archipelago fleet 's firepower , provided it with better defensive capabilities , and made possible more efficient fire support in amphibious operations .
