Give me some ideas on how to mount a 3x5 flag on my boat, 210 sundeck

That's gonna be a beast of a flag on a 210! I like your patriotism (assuming it's the US flag you'll fly) but you'll need to anchor that bad boy a little better than most. Perhaps a rod holder flush mounted into a gunwale.

I'd personally skip the surface mount style for a flag that big. I don't think they'll survive...

As was mentioned, that would be a pretty large flag for a 21' boat, although maybe you're thinking of an extra large one to fly around Independence Day? I sometimes fly an extra large flag for the 4th too, mounted in a rod holder. Perko and Taylor Made have flush mounts that have angled sleeves under the deck that look fairly hefty, compared to the ones that clamp onto a rail. I haven't reached the Burger King sized flag yet... not sure my rod holders would even be up to that task

Typically, the ensign is around 1" for every 1' of boat length. So for my boat, 36' LOA, I would use a 24" x 36" flag. For a 21' boat, the suggested standard sizes would be either 12x18 or 16x24. The staff you mount it on should be 2x the vertical dimension of the flag, so a 12x18 flag would have a 2 foot staff, a 24x36 would have a 4 foot staff.

Here are a couple places with info:
