You'd want to wear your warm jumper to wander those shores.
So nothing you could swim in, but it would be relatively easy to build a boat.
Hmm, come to think of it: Titan's gravity is 0.138 g. So you might be able to stay afloat in liquid methane by actively swimming upwards, even if you can't float.
Similar to how birds stay afloat in the air, despite being heavier than air.
Wouldn’t it dissolve a lot of things, including space suit seals? If it wasn’t for the extreme cold embrittlement anyway.
Basically, you wouldn't want to build them out of materials that are useful at human room temperature, but you could perhaps build them out of materials that are liquid or even a gas on earth, but solid at Titan's temperatures. (No clue whether ethanol would be good, it solidifies at -114.1C, but I have no clue what kind of solid it would be.)
War pigs is positively cheerful compared with Titan! At least Titan sort-of avoided another Stephen Baxter trope that annoyed me when it kept appearing: how humanity's first star ship, last-chance rescue ark, etc always somehow gets taken over by a gang of lowlife characters who were included for bizarre plot reasons / sneaked onboard at the last minute / etc. Although in Titan, instead of stowaways, madness due to increased radiation exposure turns one of the crew into the deranged psycho who has to be managed by the others.
Many of his books also include a disgruntled ex-astronaut partnered with some all-knowing alien / robot / immortal / etc that provides exposition / info dumps as required when Baxter decides to 'tell' rather than 'show'.
