Thanks for your interest. Here are the answers to your questions:
1) about 20 teams, at least that is what we have averaged this year through our first 3 events.
2) payout is 80% of the entry fees, the payout break down is in our tournament rules on the website but to save you time: 1=35%, 2=25%, 3=20%, 4=15%, 5=5% We only pay out top 5. We do have a big fish pot that is 100% payback winner take all and that is $20 per team.
3) the minnow level membership is membership to our club, this includes your spouse and kids under 18. The increasing membership levels include free banquet tickets and additional recognition through club events.
4) Yes the $25 membership fee is payment for the minnow membership level. This is an annual fee to be able to fish the club events.
Let me know if you have any more questions. My phone number is on the the tournament sign up sheet.
