Over water paths are good, but not because of reflections.  It's more
because of good line of sight, and also there is often an inversion layer
(one for the meterologists ;) ) over the water, especially on warm days,
that forms a duct which helps signal ropagation.

Reflections from the water can actually be a problem, but as WLANs use
spread spectrum, this problem should be minimal, due to the inherent
characteristice of SS (because the wide bandwidth SS employs, only a small
part of the signal is affected by multipath fading at any given time).
