Although I had trouble getting the dimensions correct at first, I finally got the layout right. Ordering was intuitive. I ordered the install kit for each side because I was afraid to run out while applying the second decal. I could’ve ordered just one but if the decals were bigger, I’d err on the side of caution and order two kits. The decals were easy to install even though my husband and I argued about where they should go; he wanted to put them under the “Cobia” at the back end of the boat. We wound up putting them about lined up with the center console. I would definitely order from boatdecals.biz again, and will tell anyone who asks where we got them from.
