There are probably 5-10 threads already on this topic. If your mast is properly sealed you don’t need the float. The boat will come right back up from turtle (if it ever turtles) by sitting on the back of the leeward hull. In fact, the increased weight aloft will actually make you more likely to capsize.

The only argument that I can see is that if you got tangled in lines as you went over a mast float might keep the boat from turtling. I have liked a couple ideas from the past. Like, sewing heavy duty Velcro to the top of your sail and Velcro a foam piece to that when you want the mast float.

I have heard of boats with wings having trouble coming up from turtle. In that case there used to be a product that had a heavy duty balloon at the end of a hose which was attached to a co2 cartage. This might be nice to have if you are on the big ocean or lake with no one to help you.

Of course you could just buy the mega bob. Many people on this forum have done that. I know Jim Hoying did it on his P18.

Hope this helps,

Matt
