unlike many of her half-sisters, "sapphire" seems to have never had additional guns added to her after completion; indeed by 1666 she carried just 36 in wartime (and 30 in peacetime), with 12 culverins and 10 demi-culverins on the lower deck, and 14 sakers on the upper deck. "sapphire" was wrecked on 31 march 1670 when she was deliberately run aground at sicily to escape from what her captain, john pearce, thought were four algerian corsairs. they weren't, and pearce and his lieutenant, andrew logan, were shot for cowardice at deptford on 26 august 1670.
