Severne Dyno 2021 - Thruster Fins

Tuning. And no the gaps don't matter unless they're huge. By that I mean for freeride with no blankers in, and even then its going to be just a bit of looseness sometimes

Easier to cut n past others' work
From Black Project fins:


To promote turning a smaller fin with more curve will help you carve tighter. This is an excellent opportunity to try out a 3 fin thruster set up.
While slower than the single fin option, thruster fins help to maximize the turning ability of your freewave board, which has a straighter rocker line compared to a full-on wave board. The Freewave Thruster fin set will be ideal, choosing the right sizes will depends on your board, weight, sail and conditions.
Check the Freewave fin size guideThe Freewave Thruster fins are designed to bridge the gap between our wave and freewave ranges.
The individual fins are the same design as our thruster wave fins, but in bigger sizes and combinations. The size guide is optimized for this type of sailing with higher volume, flatter rocker boards and more powerful sails.
When sailing predominantly in onshore winds and at beaches with strong currents, choose a bigger set of fins than you would use in side shore conditions. If you are used to the feel of a single fin then start off with a larger rear fin and over time you will get more comfortable with a more balanced set up.
Bringing your fins closer together will make the board looser, whereas moving them apart will increase grip and make the board feel stiffer.
It is a good idea to have one set of front fins and two rear fin options, this gives you maximum tuning range.
The extra wave performance of thruster fins will enable you to turn and pivot your board faster, remain in control in high winds and get to grips with wave riding.

Depending on your weight and size of your board you will want to choose a sail between 4.5 and 5.5m.

With the mast foot closer to the straps and fin, the board will turn easier."
