Smith rod holders are inexpensive iron racks with few features, however they make 3 and 4 pole holders designed to clamp on to pontoon rails, which could be easily modified to go over your cleats. that being said if it was mine id find a way to mount short perrotis, or since your worried about the weight pulling holes out somethin light with a flat base like tite-locs or hi-techs, the hi-tech guy is on here and seems very customer oriented i'd prolly ask him.
