I've seen quad holders, but never six. It'd probably be too much stress on the mounting point. For big boards, I assume you're looking for tube style rod holders and want six per side. If you have the gunwale space, you can fit six rod holders in a 36 inch section of berts track. You would need a flat spot that's 3 1/2 x 36 inches and the track would cost around $100 per side. If you can muster a 3 1/2 x 4 inch spot anywhere on the gunwale, you can mount a Cannon 18 inch pedestal track. You can fit three rod holders in that and I'll include a picture of mine with very inexpensive rod holders mounted. These 18 inch pedestal mounts have been on clearance on the internet for the last year and can be found for about $20 each. Here's a link. You'd need four of these to be able to mount six rod holders per side. http://www.tackledirect.com/cannon-p...n-1904006.html.

I know everyone likes to run cisco, berts, and Cannon rod holders, but there are less expensive alternatives. I use Scotty Rocket Launcher rod holders. Walmart.com is selling them for a whopping $11.66. Search for Walmart item number 552658879. Scotty has come out with some lockable mounts for these rod holders, also at Walmart for $8.34 each. Search walmart.com for part number 552657138. You'd also need track adapters. Luckily, Walmart has those also for 12.50 each. Search walmart part number 552658510. A track mounted Scotty rocket launcher costs 11.66 for the rod holder plus 8.34 for the mount plus 12.50 for the track adapter for a total of $32.50

If you went with four cannon pedestals and 12 tube rod holders, you could set your entire boat up for:

Pedestal Tracks 4 x $20 = $80
Rod Holder, Mount, & Track Adapters 12 x 32.50 = $390
Total $470
