Your best bet is get a hold of a client and server that supported boats... I believe 0.4.4 did off the top of my head, though I could be wrong. Then, add support to the current EQEmu build for the 0.4.4 "a bit more classic" client. I am sure this is possible as 0.4.4 client is well documented and was imho the first version of EQEmu that was really becoming decently playable. This client used UI 2.0, so it isn't classic completely, though that is nothing a classic splash logo and UI can't take care of. You may want to ask FNW or Doodman what would be entailed in adding support for an older client. Of course, talk of this patch and where to find it would be strictly forbidden on these forums so keep that in mind.
As for Windcatcher's client... I don't want to say too much but it is indeed impressive. Just a cravat, out of the box Live zones will not be supported. A custom .dll will have to be written to allow those zones to work. This is done purely for legal reasons. Though, I am fairly certain Wind has done nothing to the client to prevent support, just isn't going to add it
