Aerospace has used winglets for more than 30 years. They must know something about efficiency since you see it on almost every commercial jet. Rainbow Fin Company has incorporated this winglet technology to our fins and we are proud to introduce our "SPEEDWING" fin line. By adding the winglets to our fins we have made a major leap forward in fin design. The winglet converts the drag caused by the vortex at the fin tip into apparent thrust. When surfing with the SPEEDWING, you will feel like the fins are slipping through the water, which means that you don't feel drag. One of the most repeated comments about the SPEEDWING is" IT FEELS LIKE I HAVE A FIFTH GEAR ON MY SURFBOARD!" Take your surfing to the next level with the SPEEDWING.
Sold as a pair of side fins.
QWhich is the size of RFC FCS Speedwing? Thanks for answering
AThe RFC FCS Speedwings have a depth of 4.65" and a base of 4.25"
Qdo these fins acctually do anything? they just seem like a gimmick to me, would be cool if they did what they say they do.
AThe following wikipedia page explains the use of winglets in aviation to help reduce drag and this is why rainbow fins developed the the speedwing so that drag was reduced and speed was increased. http://en.wikipedia.org/wiki/Wingtip_device

A very good fin set if you are looking for as much speed as possible. They have a noticeably low drag.
