Abaye: explains the following Machlokes:
R’ Gamliel: A Sukkah needs to have qualities of permanence and the middle case is lacking that because it will be blown away on the ship, with its Normal Boat Winds.
R’ Akiva: Sukkah only needs to be a temporary dwelling place and that is defined as dry land requirements. Withstanding boat winds would make the Sukkah have permanence.
Both opinions seem to be in agreement that if a Sukkah can withstand normal winds on a ship it would still be considered a “temporary dwelling place.” Even though Boat Winds are commonplace on a ship and the Sukkah would not last, both opinions define it still as a DWELLING PLACE, never-the-less. This shows us we NEED a lot less than we think we do.
E’s Lesson: Do not get lost in our luxuries and appreciate that we only really NEED a temporary dwelling place in this world. All the extras we get blessed with must properly be utilized for our service of Hashem.
