Hi Chris, I run 3 Penn downriggers on Snoopy-C, so don't think 4 would be much different. I have 2 on the gunnels just ahead of the fuel fill pipes, and on port, I have another about midway between the aft downrigger, and the cockpit bulkhead. I use 4 ft Penn electrics with swivel bases. Keep the forward rigger at 90 degrees to the gunnel, and the aft rigger I swivel just far enough of dead aft that the ball will clear when pulling it in to set the clip. The 4 ft reach just clears the back of the boat. I use the line retrievers on the cable so I can reach the clip when rigging. Need to be careful though, and if I had one on the kicker side, I'd be a bit more concerned around the prop, although most of the Canadian guys use the deflector ring around the prop on the kicker to stop the cable entanglement. Regards, Ron
