Thanks for all the thoughts and ideas everyone. We'll see if I end up doing anything or just spitballing more and more. No cost for that.
Parking/storage is a factor, as is my tow vehicle (Toyota Sienna w/ tow package), and cost. I'm honestly not even sure where I'd put anything on a trailer. I don't have a garage, and my driveway is constantly bombarded by needles and branches in the winter. But that sort of impracticality won't stop me for ever.
Having something small but Neah Bay-worthy would definitely be cool. The superior bluewater/offshore capability of RIBs compared to similar aluminum or fiberglass boats is definitely a factor. The last time I was running a whale research RIB out of Sekiu was during halibut season. We'd get looks of amazement from the tough grizzled fisher folks in their 32' Duckworths and so forth when they asked us where we'd been. "You went out to Swiftsure today... in that?!" "Yep. Twice!"
