Forget the trifecta, here's the quinella.
21' Checkmate "StarFlight" Merc 275 Verado (90kts+
)
17 Boston Whaler Montauk w/ Merc 90 Optimax - 40 kts
20' SeaCraft Seafari w/175 Verado - 45 kts
31' Bertram FBSF w/ twin 3208ST 600hp Caterpillars (gear-driven superchargers AND turbocharged w/intercoolers) 48 kts
72' Rybovich "Cutting Edge" engine types unpublished, but at sea trial off Palm Beach in '99
Top Speed was 51 kts with full fuel and water!! (Might as well wish for the very best, n'est pas?)
Although I have to admit, I'd be happy with any two of the above
