So, a ST 44 is around 24,000 pounds in light condition plus another 8,100 pounds of fuel and water when full plus, say another 1,000 pounds of "stuff." 33,100 pounds all up. The weight seems doable for a lift. The support needs to be well thought out with pilings deep enough and stout enough. My 20,000-pound capacity DECCO boat lift supports my 12,000-pound plus boat lift using six 40-foot pilings sunk about 20 feet into the sandy bottom here in NWFL. For a ST44, I might want a 40,000-pound lift, but the lift maker would be a better place to check.
