This may be farther then you are willing to drive, but Randy Ratliff(troutfishers guide service) has one for sale. I can get you his email if needed.
I have a water ready 2005 14′ Star Wonderbug and custom trailer for sale.
The raft has wooden standing platforms front and rear, lean bars front and rear, full pulley anchor system, Carlisle oars with spare oar (oars shown do not go with the raft).
Trailer has custom roller system, front storage box and winch system.
Counterbalancing is where there’s enough weight in the handles that the oar wants to ride horizontal in the oarlock; it reduces the load on the rower by helping to hold up the oar blade under it’s own weight.
The trailer was purchased from a local trailer maker and modified by me with a roller system for the raft to glide on as you winch it on the trailer. I have about $1200 in the trailer. The trailer is 5 ft wide by 14 ft long (bed dimensions)
The oars are 9 1/2 footers.
Just as John said a good trailer and full pulley anchor system, like mine has, will help as you spend the day on the river.
John and his Dad have spent a few days on the river in my raft and can tell you how my system works well.
