JJ_, why do you single out the Blade when the Viper, Taipan and Blade all have the same mast section. If you want lightweight masts with corrector weights on the top, go Stealth or buy a custom carbon mast. Boats can be delivered without masts so you can buy a custom mast.
If you want to go surfing, a surfboard or a windsurfer is much better suited than any cat. Why dont you tell why you think you want an F16, where you sail, your experience with cats and I am sure you will get feedback on wether a F16 is the boat for you.
