Think you`ll find Hydroptere is not a single craft but a series of crafts designed and built with specific records in mind. The craft recently used in in 500m and 100m records would not be used for "passage " sailing records. (Not in its current guise of foiling rudder and foiling amas;with water balast exchange) (apart from perhaps channel hop; on selected days)
(Imagine transfering ballast every tack; I diont think even Banc Populaire (a non foiling Tri ; which unusual to non-foiling Tri`s raises its middle hull to gain extremely large anti heeling moment.; only thing in coomon with Hydroptere)
I dont think Hydroptere 500m record holder will ever be seen mid Atlantic ???
