So... The boat question !
(I could have sworn I saw a video where you were complaing about ill defined questions online....)
Presuming the ice is within a sealed environment within the boat & the ice is above the level of any water already within the boats hull it will bob up and down by a tiny amount.
- Volume of the ice vs water becomes a non issue in a sealed environment, purely a mass issue vs the amount of water displaced by the boats hull as does any air resistance / displacement.
- Potential energy will be transmitted from the ice to the hull due to the height of the ice above the hull temporarily forcing it to a lower level in the water & if you really want to be fussy the increased gravitational effect on the droplet of water would increase it's weight as it dropped.
