I have a Bennington fish and cruise that I fish from. I had Gene that makes the spyderloks make me a pair of custom mounts. They bolt on the rail then I mount the crossbar from the spyderloks on them. I unbolt one hand screw and can take the entire rod holder set off. I am fishing in the morning and will get pics. Also the spyderloks are without a doubt the best holders I have ever used.
