2nd vote for good idea
We added last season to our 33.5For a 27 footer, you could get away with the twist lock version made by forespar. We added two deck chocks for storing as we didn't store on the mast as it adds too much weight aloft. One eye attached to mast is plenty with this kind of storage. Unless into racing and super fine tuning you don't need a ring that slides up and down on a track. More stuff for your 150 to hang up on on a tack. Main thing is to get a pole that is as long as the foot of your largest jib/genny and to mount your padeye on the mast so that in your primary position (set up for light to med air with full 150 flying on our boat), that is to say, the way you will use it most often, the wisker pole is horizontal or paralel with the water.It will make downwind sailing twice as fun and fast. Have fun.Doug
