流氷の多い地域は、船のサイドにタイヤをぶら下げるのはいかがでしょうか？ If you live in an area with a lot of drifting ice, why not hang a tire from the side of your boat?

 流氷の多い地域は、流氷のせいで、流氷と船との衝突を避けないといけないです。危ないから船を出しづらいであろうと推測します。

バンパーが有ればいいかも。

難しい構造を発明するのもいいけれど、それはまた先のお話。とりあえず、船の両サイドに、タイヤをぶら下げて、バンパーとして利用するのはいかがでしょうか？流氷と衝突の際、クッションとなり、意外と流氷の中をすすめるかもしれません。

In areas with a lot of drifting ice, ships have to avoid colliding with it. I imagine it would be difficult to set sail because it would be dangerous.

Bumpers might be a good idea.

It would be nice to invent a complicated structure, but that's a story for another time. For now, why not hang tires on both sides of the ship and use them as bumpers? In the event of a collision with drifting ice, they would act as a cushion, and might actually make it easier to navigate through the ice.
