Noodles will float your boat
Phil - check with Hunter - that is probably the same float for both boats.
I can attest to the tippiness of the 146 - I turtled mine. I am amazed at David's experiences in never tipping his 170!! I have heard from many others that they are tippy, but David is proof that it's in the sailor too!!
I used Glenn's advice, with a sligth variation.
I slipped swim noodles down from the top of the mast, then sealed it. Also put one in the boom, though did NOT seal it.
I wanted to put a windex wind vane n the mast head, so didn't want the float.
My posts are also in teh archive.
Haven't yet tested mine, but Glenn and others have doen extensive testing, and verufiy that it works.
If you've already ordered the float, and Hunter confirms its the right one, might as well just go with that.
Enjoy!!!!
