Looking for a holder which could hold either (2) wakeboards or (1) wakeboard and (1) knee board. Also will this hold fishing poles?

We do offer a double wakeboard rack. The only combo rack we offer is a Wake/Surf rack, the larger fork fits boards up to 2 3/4" thick. We also offer a Kneeboard rack that fits boards up to 4" thick. Please see the link below to visit our Rack page for all the options we offer. https://monstertower.com/tower-accessories/wakeboard-racks.html
