Let's have a look at the map again...

As a tangential point, but still on Leshp in general and it's place in Circle Sea cultural importance (as a Mediterranean style cradle of civilisation ) and of Holy Wood and it's sunken 'city' (which really is too close to Leshp for co-incidence), I'm rapidly coming to the conclusion that a retro mage-war Discworld Atlantis/Indiana Jones-style story is waiting to happen if Terry is spared long enough to get around to it?
The entire Circle Sea is too super-volcanic caldera-like for comfort in fact.
OK - Atlantis-style theory
a) Leshp is mostly built on pumice - that's an aerated volcanic rock which is formed during an eruption when super-heated air-borne lava hits a large expanse of water...
b) the buildings on Leshp are a mix of earlier cultural architectural styles from societies bordering the Circle Sea.
c) we have another, permanently sunken city off the coast of Holy Wood and Para Mountain (8 & 14) that we've already seen in MP (blue text).
....(i) Terry also mentions the occasionally floating island of Leshp in either CoM or LF that he develops fully in this book
d) Vetinari found records concerning Leshp in A-M's municipal archives that dealt with previous risings
e) because people had built on Leshp before at various times this indicates that previous risings may have been for longer periods or even from before it sank - is it not therefore likely that knowledge of it's existence would have survived from even earlier times as folklore and legend?
In that last point Quirm (24 on the map) is not so far off that they may have had tales of the island too, perhaps from survivors of the original sinking? So Leonard, being that sort anyway, may also have investigated the odd tales and went to the general area to find out more. Whether or not it was on the surface is perhaps not so important - he could have gone there via a conventional boat but, this is thing - why would he build the Boat in the first place if not because he extrapolated and wanted to find out if the island did indeed float and so could sink as well (demonstrated in a & b) - the seaweed etc all over is proof enough of that surely for someone as clever as Leonard isn't it...?
