Weathertight means that in any sea conditions water will not penetrate into the ship.
Watertight means having scantlings and arrangements capable of preventing the passage of water in any direction under the head of water likely to occur in intact and damaged conditions. In the damaged condition, the head of water is to be considered in the worst situation at equilibrium, including intermediate stages of flooding.
简单来说,weathertight防泼溅,watertight防水压
