Ben, the course plays from three sets of tees. There were sand tee boxes installed last year, and those are all no more than 5-15 yards shorter than the red tees, which total 2304 yards. The distances below are the reds, and I have take a guess in the yards shorter for the sand tees.
1: 299, 10 yards
2: 242, 4
3: 313, 8
4: 256, 10
5: 71, 0
6: 304, 6
7: 287, 10
8: 316, 8
9: 216, 3
I will double check the distance from the sand in the next week or so.
You will find St Martins in great shape. It has been restored over the past 18 months in accordance with a master plan developed by Keith Foster when he was working on the club's Tillingahst course - Wissahickon. All of the restoration work at St Martins was done by in house maintenance staff, making it very economical and a great living laboratory for the work at Wissahickon.
Here's a photo from early May of this year looking up the 1st fairway on the right with the 9th fairway on the left.
