I had my old Main re cut to loose foot when I had it refurbished by Sail Care this included the reinforcement of Clew & Tack.

Thanks Doug, & Dave...I can recall seeing the "shelf" you mention in my main when there's no reef in.
When someone saw a pic of my boat under sail and said my "first reef" may be what's called a "flattening reef" it all makes sense, because when I use the first set of reef points I get a definitely flatter foot of the main without that "shelf" at the bottom, and with the reef out it does have a bit of a "pocket" above the shelf for light air sail shape.
This isn't the original main, though I did get that with the boat...this is a newer main bought by a previous owner, by North Sails, three reef points, including the first rather small "flattening" one, a more significant second, and a pretty deep third. I've only ever used the first/flattening one so far.
cheers, John S.

Sails designed for a loose foot usually have a roach added along the foot of the sail to help "capture" the air flow. A sail cut for a bolt rope usually has a small shelf built into the foot to assist in this capture as well as shape the sail for lighter conditions. I don't think using a sail cut for a bolt rope foot as a loose foot ( not threading the bolt rope in the track) will enhance sailing performance.
It is more a useful decision when ordering a new main. In this case I also prefer a loose foot.

Funny, I was thinking about this question myself as I start to anticipate
sailing season...
Same goes for M17 I assume. My old '74 has foot in track.
Key question would seem to be whether clew and tack are strong enough...how do we determine if we have "proper" reinforcement, Dave (or anyone else who can respond to that...)?
cheers, John S.

sorry ... computer decided to send as i was typing.
you MUST have a vang ... it minimum to keep the boom from rising when sailing off the wind.
loose footed is wonderful. makes the sail shape better and provides for easier adjustment of the sail's draft using outhaul. NOTE: the sail needs to have proper reinforcement at the clew and tack.

I have been sailing my M15 with the main fitted in the boom groove but
recently it has been suggested that flying it loose footed, with only tack and clew fastened, will improve performance. I have also been advised both for and against adding a boom vang. I appeal to this forum for an experienced opinion.
