The "Five-Minute Rest" concept is ridiculous if you take it literally. I never have such a strict interpretation in my games, it seems so silly.
Unless I specifically decide on running waves, quite a few things count as a rest. Searching through bodies, scouting the hallways for patrols, spending a few minutes to sort out a complex puzzle left by a mad archmage.
Even the example with the ships and the swimming would either be a chain-encounter, or individual encounters.
Now, for fun:
"Lets set down and have a cup of tea gents, I need ta rest my weary bones."
"We just stopped give minutes ago, why do we need to rest again?"
"Well, that squad of orcs caught us unawares, and .."
"Fine, you sit there if you want. I'm willing to bet those orcs have friends, and I sure aint gonna be sitting around waiting for them to find us."
