I sail on a friend's Tartan 28 alot. He has 2 different mainsheet
fittings on the boom. One directly over the traveller that is used
without the dodger. One is further aft on the boom and is used when
the dodger is up. It still has a little interference with the dodger
up and sailing off the wind, but we just unclip the side panel of the
dodger and it's no big deal. He has considered putting a padeye on
the cockpit sole, just ahead of the wheel. That would remove any
interference with the dodger, but lose the adjustment with the
traveller, which is ok for cruising.

For a boat that will be used a lot with non-sailing guests, a cabin
top or aft mounted sheet would be safer.
