> Every right to go to another countries waters...?

Yes.

First, the Houthis aren't the recognized government of Yemen by any country except Iran; they don't (legally) control Yemen's territorial waters.

Second, even if they did, the vessels are permitted under international law (including treaties Yemen is subject to) to transit the strait. https://en.wikipedia.org/wiki/Transit_passage

> A blockade that has killed 0 people I would add.

If you run around shooting a gun at people and only hit their cars in the process, expect to still be shot by police if you don't stop.

> For clarification, do you believe preventing aid from entering gaza under the threat of violence is self defense...

No, I similarly believe Israel is violating international law in various ways. I'm opposed to their blockade of Gaza.
