What size "bob" for a 16?

Baby or full size?

My mast fills with water faster than the Titanic. Numerous sealing efforts have been to no avail.

A mast head float is what I seek. I know of a Baby Bob for sale I am unsure if that will do the job.

Thanks

A mast float will not solve your leaking mast problem. I have the baby bob and my mast floats, works great. If your mast leaks, you'll need a hot air balloon instead.

Where is your mast leaking from? People here might be able to tell you how to address it if you tell us where it leaks.

Baby bob is the right model, but you need to resolve your leaking mast, obviously.

Put the mast in a pool or lake to find where it leaks.

If it leaks from the top or bottom of the mast, one of the mast end foam plugs (one at each end) will need to be sealed. You would need to remove the mast base or mast head. I would think filling the area with expanding foam would seal it.

If it leaks around any rivets, you can seal with silicone or better yet replace the rivet using ss rivet w/ a casing.
