who ever used the sidefins on the GO?

[crazychemical]

see tittle! I took out my GO139 recently in Leucate and because of a few crashes somehow on of the holes for the sidefins which i never use, and which, on the 139 model would have very little to even no use at all, seemed to have opened and my board was spitting water through it! So i asked myself why ever did they put them on? And i mean ... u don't even get the fins standard with the board so like ... few people really bother to use them.
