Jflex,
It is very easy to start a club up, you just need a meeting place.
Pubs and workingmens clubs are good if you are old enough. If you have your meetings on a slack night for them, say a Tuesday, they will usually allow you to use a spare room free of charge or a very low rate. If it is a workingmens club, just getting the members to join is usually enough, some can be as low as £2 a year for membership for each member, and this will also allow the use of the club and it's facilities at other times.
Get together your band of merry men, select a chairman (he keeps control of the meeting), a secretary, to take notes about the days meeting, and to read the minutes of the last meeting, just to jog peoples memory. Plus any follow ups from the previous meetings. He will be the most important one, as it will be him/her that will usually take actions on what has been discussed, things like advertising, buying articles for the club as a whole, say a canopy for outside meetings etc.
Then you will require a trustworthy member to collect club fees, open an account for the club, pay collected money in and issue money out, usually to the secretary to do his purchases or refund him for personal money spent, envelopes, stamps, phone calls etc. He will also be required to keep up to date accounts of the clubs financial goings on.
This is a club I helped to start many years ago, and over the years has grown to what it is now. We started off with about 5 or 6 like minded people meeting in a pub. Once we had obtained permanent sailing water, we had to form the official club as finances became involved.
These are the rules of the club, and have been expanded greatly over the years from when we first started.

So basically, it is someone with a load mouth to keep control, another that can read and write, and a tight wad who keeps control of the cash.
Hope this helps you on your way.
