TunaHead in California here. *I just got my V a while ago and haven't gotten it in the water yet. *I am setting it up for diving as well as fishing. *I bought a used teak swim platform with rails on both sides and a drop-down step. *I bought it from these guys but you can probably get them from Flounder Pounder as well: ($75 + $15 shipping vs ~$150 new)

With the swim platform installed this should be a fantastic dive platform with lots of open deck space for a few folks to get in/out of gear. *Just need to figure out what I am going to do for storage of tanks. *Lots of options out there for this but I want something removable. *I'll probably end up with a track system like these guys offer:
