Lab Partners, a Rosborough 246

She was lovingly enhanced to her present excellent state by a superior craftsman who did fine woodworking, sewing and electronics with the skills the rest of us can only admire.  Thank you Rip and Beth for selling us your fine boat.

Shearwater V loaded for the trip home to the Moose

We picked up Lab Partners at the Keystone Heights home of the previous owner. Rip went well beyond any previous owner I have known and helped fit our Anderson Load Leveling trailer hitch to the trailer in the rain and cold. We had an uneventful trip to her new home the following day.

Along the way, we stopped for a nice overdue lunch at Blue Water Bay.

The gallery below has the pre-purchase images provided by the previous owners. Rip and Beth took superior care of Lab Partners, adding enhancements to make her even more livable.

After purchase, I added (with significant help) a Andersen Weight Distribution Hitch to the trailer. It is about a $300 addition but requires a special ball mount.

I highly recommend the Weight Distribution Hitch for sway control if you are towing with a moderate size vehicle.

I will provide (or remove, your choice) the left portion of the photo below – it is attached to the trailer. To use, you must purchase the right portion to insert into your tow vehicle’s receiver. With this weight distribution  hitch,  she  tow  easily  with my  GMC  Yukon  fitted  with  a factory  brake  controller.

The ball mount is available from Andersen at:
