Extremely. They are quite slow laterally (a couple knots while docking), the lateral currents (which are not constant or unidirectional) reach 2-4x+, throwing them into whatever happens to be in the way. AFAIK the bigger issue is that the boats are grounded so violently when the water recedes that the hulls get destroyed before they even have a chance. This tends to be why they put everything they have into getting further out to sea the moment a warning is issued.
