We’ve talked about the simplicity of McConks’ Click Fin side fin system, which you can read here. If your McConks inflatable stand up paddle board has a US Box (single leading edge mounted screw head) then it’s just as hassle free to attach. Here ‘s how in six easy steps –
Place the screw plate in the box track via the gap at the centre of the fin box. We find that screwing it to the fin bolt first and using the fin bolt to drop it in place works for those less dextrous poeple (like us!)
Slide the screw plate towards the front of the box along the plate track. Again, you can use the fin bolt to do this if still attached, or if your fingers struggle to get in the box. (Note, if you are using one of our specialist 4.7″ river fin you’ll need to slide the screw plate backwards)
Slot the fin pin into the gap – make sure the fin’s the correct way round. Its angle (rake) should be leaning back towards the tail.
Slide the fin back towards the tail (or forwards towards the nose for the 4.7″ river fin) a short way to ensure it’s firmly secure in the track.
Rock the fin forwards and line up the screw hole with the screw plate you attached earlier.
Using your thumb and finger turn the screw until tight.
Once you’ve affixed the centre US Box fin you can tune according to your wants and needs by moving it forwards or backwards. Rule of thumb dictates the further forward your fin in the box is the more manoeuvrable your SUP will be. The further back you have your fin the less manoeuvrable it is. You can also change the ‘feel’ of your inflatable stand up paddle board by changing the size of your fin. Experimenting with different configurations is always worth doing to find your best fit.
