C 28 Bridge clearance w/mast up?

[CaptT]

Does anyone know the air draft for the C 28 with the mast up? We are headed to the Keys, from Tampa Bay, and have a few bridges to pass under. I know the clearance is 9'1" with the mast down but searched the forum and can't seem to find clearance with the mast up?
I'd like to leave it up for anchoring out at night but if I have to lower and raise it, with my screwed up hands, I'd probably spend more in wing nuts than fuel.
Thanks in advance for any help with this!

In another thread, Kevin from FM said they measure the air draft with full tanks, but light load:

This topic had me asking the same question - my plan was to measure the mast itself and add to the 9'1" (plus some extra for safety), since that would seem easier than trying to measure everything from the waterline. If someone has already done the math I'd be interested in seeing it as well though.

Good idea. When I get over to the marina I'll try it. With an "Admiral " who likes to take a complete chef's kitchen and a wardrobe to match, our boat doesn't know what a light load is.
I've seen the information on the 29 Rangers and the 31s on other threads but nothing on the Cutwater 28 with mast up. I'll let you know what I measurement i get when I implement your plan.
Thanks for the reply.

I use 13’ as my limit. That is with the VHF antenna down.

Thanks James. That sounds like a good round number to use. I've got a feeling when I do get around to measuring it I will probably get something like 12' 10.5" which will change quickly when hit with someone's wake.
13' sounds safe. Thanks again.
