I know it is just a rant, but I have to respond when someone claims that CompTips are dangerous.
The CompTip is a great solution to a hopeless situation concerning electrocution. Hobie Cat is the only company who stepped up and offered a safe solution.
CompTips add just one additional leak possibility (the connection joint) compared to an aluminum full length mast. The taper is a side benefit to the molded process and allows a lighter and better aerodynamic upper mast for higher performance.
Every mast made has a potential to leak. Everybody knows that. Seals and sealant do not seal a mast permanently. Stick the mast head to 30 feet depth, you may have problems. Especially with an older boat.
Carbon masts? Talk about care and maintenance.
