This is the genuine Starboard Astro SUP fin in the Race 23cm size, with a slot based fin head system.
This injection-molded (PA+GF 30%) Starboard Astro SUP fin provides added flex suitable for larger boards…in this case the Astro race, touring and faster profiled inflatable SUP boards.
This fin is designed for flat water predominantly, so it’s ideal for a rider looking for directionality and stability from their board, without going to the expense of a carbon fin.
The fin box system is the slot based system, whereby the fin slots into the fin box of the board and is retained in the fin box with a stainless steel grub screw.
Genuine OEM Starboard replacement or spare fin.
