I got them fitted and IMHO have made a marked improvement on preformance. Gets going on the plane V fast especially when a heavy lot is on board. Into wind keeps the nose down. Down wind ya have to be a bit careful as the nose drops fast if you power off.
Now everyone will say - you would say that cause you fitted them !!!
But they do the job well on my small tub.
divide that cost by 3 and you would be more in the ball park.
Ok - let the abuse flow
Ps I have installed a pulley to raise them when Launching and recovering - could easily snag and get damaged. would recommend - but what do I know (before someone else says so)
