Product Description

The Rainbow Fin Company's Costa Azul is a classic fin that Rainbow has been making forever, and for good reason, because this fin has withstood the test of time. The fin comes in 5 different sizes, so the size you choose will have an impact on the setup and surfboard to pair it with, and the conditions to use it in. At the smaller fin sizes, from 6" to 8", this fin is best-suited as a center fin supporting 2 side fins in a tri or 2 + 1 setup. With that setup, you can screw the Costa Azul into all kinds of boards, from Spoons to Longboards, optimally from 7'6" to 9'6". But the Costa Azul can be used as a single center fin, too, with surfboards on the smaller end of the spectrum, or if you grab the 9" or 10" Costa Azul, you can set that into your longboard as a single center fin. If you surf in a variety of spots, on a lot of different surfboards, or with a number of fin setups, the Costa Azul is a great fin to have in your arsenal!      

As mentioned, this fiberglass fin comes in 5 sizes from base to tip so you can really customize your surf experience: 6", 7", 8", 9" and 10".  Because each fin is handmade in California we cannot guarantee the colors of the fins available.  For additional information on surfboard fins and fin setups, check out our Surfboard Fin learn section.

About Rainbow Fin Company:  Rainbow was started back in 1968 in Santa Cruz, California, by a group of Santa Cruz surfers who were looking for fins to ride for their own boards and to sell to others in the surfing community.  Since then, for over four decades and counting, and through the evolution of fin setups, designs and constructions, Rainbow has been relied on by surfers throughout the country and around the globe to provide them with the perfect fins for any conditions.  Whether your go-to is a longboard or shortboard (or a SUP), a single, twin, thruster, quad, or five fin setup, or have FCS or Futures, Rainbow has you and your surfboards covered.
