Sailing the P16 without a jib is very okay.



The trick is that you need to rake your mast a little more forward. This means that you need to put the sidestays a hole up and the forestay a hole down in the plates. When your P16 is well balance with a jib than just on hole or at max two hole should the trick. this will loose all weather helm when leaving of the jib.



Personally I rake my mast just to the perfect balance on my P16 whennflying with a jib and just leave the jib off and accept the small amount of weatherhelm. I'm lazy.



Tacking should be a little more difficult in the beginning but easy enough after some practice. After doing it right you'll will learn to tack well (most sailors don't ) and then you should hardly feel any difference. Then you will not miss the jib at all.



Just make sure you tack using the right technic, which is on a uni rig. head up pull sheet in, point throught the wind and immediately let out the main be sheeting a foot or so out. keep steering all the way through the turn and only when the boat has bore off considerable sheet the main back in again. With practice this should take more then 5 secs and feel easy and smooth.



Good luck
