I scanned these in big so they are clear. What these are are the Calcutta auction for the Poco bueno tournament in Port O. It is a private, invitation only tourny, limited to a 100 boats. The money pool consists of 2 parts, the entry fee pool and the Calcutta pool.
The entry fee pool is just that-entry fees minus expenses, and is paid to the winning boat.
The Calcutta is an auction. Each boat is announced and sold. This is the calcutta pool, and it is awarded to who ever bought the winning boat at auction.
What this means is that you can win the tourney, but only win $50,000 of a $500,000 dollar pot (It reached over a million sometimes). Anyone can buy anyones boat, so the the big boys bid each other up. It is a fun, and drunken, 5 hour dinner/auction. Notice that the trend over the auction is up, although the order is random. Mr Crown royal plays a part. I was second mate on Annie Fannie, #3 on the list)
