MRS Fena
With a fin under your packraft, you get better directional stability and thus also higher speed when paddling.
The fin is available in two different sizes. The small fin weighs a little less but still has a positive effect on most packrafts. The large fin is only recommended for larger packrafts.
MRS Fena is used for longer paddles in slightly deeper water and is not recommended in shallower rivers.
The fin attachment is installed in all newer packrafts from MRS, but can also be purchased separately here.
Things to consider
The fin only fits in MRS's own bracket and does not fit, for example, in brackets on Anfibio's packrafts. Also keep in mind that all MRS packrafts manufactured in 2021 and onwards are sold and delivered with fin and bracket included.

I experienced a big difference from having no fin at all. The glue that came with the hardener took a while to apply but it sits like a rock when you're done. Note that the hardener's bottle does not have a spout, so when you dose it comes a lot at once. It seemed to work anyway.
The compromise of having a small fin is probably that a larger fin makes the paddling more course stable but that a small fin does not go as deep.
The fin is a big improvement. After 2.5 miles of sea paddling with the fin, I find that the packraft is more course stable but above all that it glides straight ahead when you stop paddling.
