Old obrien sensation fin mounting system?

Question
Hi i have the board as mentioned above, but do not have the skeg fin on the back.  Is it still possible to buy one and what type of mounting system would it have.

Answer
Hey Ryan,

Your board will use a standard type fin known as 'A' box, US box, or Chinook. Readily available used on ebay or possibly your local craigslist. Look at some of the other questions posted to me and you will find a similar question about an O'brien board that has a picture of the type of fin you are looking for in my answer.

Hope this helps.
Keep on sailing,
