A very long 440 yard par 4, the 15th hole's entire right side runs along the bank of the Merrimack River.  While the fairway is quite large , there is not much room for error on the left due to high grass and trees separating the 15th and 16th fairways. Long and straight hitters have a distinct advantage here but anything less than a very accurate approach shot will leave the player with a difficult attempt at par.
