I BOUGHT THIS FOR MY FATHER'S PONTOON BOAT AND IT'S GOING TO PERFECT. IT WILL FIT RIGHT ON THE RAIL WITH NO PROBLEM. IT IS NICE TO HAVE SOMETHING TO HOLD YOUR ROD LEAVING BOTH HANDS FREE TO DO SOMETHING ELSE. COULD BE BAITING THE HOOK, GETTING A COLD DRINK FROM THE COOLER, HELP A FISHING MATE OR JUST LOUNGING IN THE SUN. IT IS MADE OF HEAVY STURDY STEEL WITH A STRONG CLAMP TO KEEP YOUR POLE FROM SAILING AWAY! OVERALL I REALLY LIKE THIS AND I HIGHLY RECOMMEND IT. WELL DONE TO THE SELLER!
