I think teak may be a mistake. Check out
www.thesmartrail.com. I installed them on my flats boat and it cut spray by 85%. They took 2 hours to install and no holes needed to be put on the boat. I feel the teak ones do not have the correct curve to catch the water and mantainance is YUCK on teak, non on the smartrail PM me if you have any q's.
