Converting Spelljammer Ships to 5E (Spelljammer Supplement)

AT this time all conversions will be based off the ship rules in the DMG page 119 and storm kings thunder page 221 pending any future published rules that would apply to ships. The squid ship based on this info has the stats of a the sailing ship listed in the DMG. also based on the text in the spelljameer books for the hammer ship I think should use the stats of a warship from the DMG and 1-9 hull point ships should use stats of a rowboat with the option of using Damage Threshold stat. Any stat not coved here should just be copied over.
