I have a Willi 2, sweet boat for sure. I use a https://www.cascadeoutfitters.com/in...ID=68&framein=
recretec frame with dry boxes that latch into the frame. I think the two boxes are 44"x20 or 22". With the dryboxes and cooler, it is a pretty clean set up, but the oarlocks are aft of center on the frame. In the rower compartment, I usually have a day cooler on one side, then 2 water jugs or 2 rocket boxes (groovers) on the other side. In the back, i usually throw gear on the floor, then cover the duffle pile with a mesh cover. The mesh cover has d-rings to secure it. I use 10' oars. The Bimini is the next addition. Have fun outfitting your boat!
