The boat location if you choose to swim there can be seen on this map:
With a Fire Mage, I managed to obtain the following in just 1 hour:
260+ netherweave
7 tomes
136 signets
1 blue
5 greens
about 35g in Junk
That is approximately 300 gold per hour on my server. In the course of doing this for several weeks, I've also made a lot more from blue/recipe/formula drops but my average is about 250g/hour at the very least depending on how many people are there as well.
