With just two races left, Newton Olympian Stu McNay is inching his way toward the top 10 boats in the men's 470 sailing event. 

After race seven and eight (out of ten races total), McNay and his crewmember Graham Biehl rank at No. 17 out of 27 teams. McNay and Biehl -- known as Team MB -- finished sixth in race seven and 18th in race eight, which were held earlier this morning at Weymouth and Portland in Dorset, England.

Team MB now has a total of 120 points after eight races, or just 97 net points if the highest score is dropped. After 10 races, the highest race score is dropped and the top 10 teams (with the 10 lowest scores) move on to the medal race. 

McNay had a couple of big finishes on Friday, moving up to the No. 11 spot after race three and four. However, he moved back down to No. 19 after his Saturday races. 

McNay will sail in the final two races tomorrow, which are scheduled for 7 a.m. EST (noon London time) and 8:15 a.m. EST (1:15 p.m. London time). The races will be shown online only, beginning at 7 a.m. each day and the medal race will be held Thursday, Aug. 9 at 7 a.m. on the NBC website.

According to the Olympic website, the men's 470 event consists of a series of 10 races. In each race, points are awarded for the place the team finishes (first place gets one point, second place gets two points etc.) After 10 races, points from the worst race are discarded and the rest of the points are tallied together.

After the points are tallied, the 10 best boats advance to the medal race. Points are doubled in the medal race (first place is two points, second place is four points etc.) and the total points after the medal race determines the final rank. 

The crew with the lowest score is the winner. 

The men's 470 event gets is name from the length of the boat, which is 470 centimeters (or 15.12 feet). The 470 is manned by two athletes, a skipper (McNay) and a crew (Biehl). 

According to his Olympic profile, McNay is a member of the Beverly Yacht Club in Marion, MA and works as a coach. He attended Roxbury Latin High School and was captain of the wrestling team. 

McNay and Biehl teamed up in 2005 with a goal of winning an Olympic medal for the U.S., according to the Team MB website. Although they are the 2011 North American Champions, McNay and Biehl have yet to take home an Olympic medal; they finished 13th in Beijing 2008.
