What holds the gooseneck in place on a C-27

...a fat goose body?
I'm thinking that the boom vang would keep the boom in place and stop it from 'creeping' up. It would help flatten the main sail out too.
Not sure about the 27's, but if the main traveller is about the cabin entrance, that should help a bit too.
Without either of those, perhaps a cleat at the base of the mast would allow you tie down the boom.

Usually a small piece of line ( 3/8" is enough) is tied off from the goose neck straight down to a cleat inside of the sail groove thus preventing the goose neck and boom from rising up. Sometimes boats have a stop lock lug inside the sail groove that can be moved into place to hold the boom in place and then tightened up to lock itself in place, Most sailboat shops like this site's store or West Marine will have the mast lug for less than $10.
Is a Cunningham necessary, or am I doing something wrong?
My concern in regards to the boom is supporting it when the sails are lowered. I put a couple of slug nuts above and below the boom to lock it in place. Is there a better way that I am missing?
Couldn't tightening the luff be accomplished by tightening the halyard?

Cagay, Your slug above and below the gooseneck is good as long as there is a little extra room above the headcar of the sail at full pull.
To explain where I'm coming from it goes like this...
1. The upper point of the gooseneck (physical highest point) should be about 6 inches below the distance of the luff at its fullest hight. This can be controlled by a stop/locking slug inserted in the sail grove over the gooseneck -or- on a mast without a sail slug groove you rig a line from the gooseneck down to a cleat directly below the gooseneck that is mounted on the mast. These limit the vertical travel of the gooseneck but do not effect the side swing of the boom. It also allows a full pull of the halyard to raise the sail with a little room to spare.
2. The mainsheet pulls the leach of the sail down tightening the sail rear end. It also holds the boom down where it is rides over the length of travel of the traveller.
3. The boomvang holds the boom down when it is swung out to the sides outside the length of the traveller. This is the area where the mainsheet cannot hold the boom down.
4. The cunningham is used only to pull the luff tighter independantly of other controls.
5. The topping lift holds the boom up when the sail is down. A boom kicker or a solid vang do the same in place of a topping lift. Some boats hang a line or light cable off the backstay to do this function but that is somewhat frowned upon as a safe practice.
I hope this clears up some of the confusion.
