since the new fix for boats dispensed with sideways facing dispensers completly reworked how boats are  dispensed rather than fixing the offset, the height of dispensed boats changed by ~ 9 pixels, this breaks boat based contraptions of the past 9 years.

beeing able to dispense a boat this much further up made it possible to use waterlogged blocks to dispense a boat without glitching into the floor.

the minium would be to actually spawn the boat 1 block up rather than 15 pixels wich would atleast fix the boat teleporting to the water surface of a waterlogged block resulting in it glitching into the floor
