Black Project SUP Sonic 18 Pre-Preg Fin
Beschreibung
The Black Project SUP Sonic 18 Pre-Preg Fin is the smallest and most agile-feeling option in this Black Project fin group. It is aimed at advanced paddlers who want the board to feel quicker to redirect, easier to carve onto bumps and more fluid in technical ocean conditions.
This is not the fin you buy because you want your board to feel calmer. It is the fin you buy because you want it to feel more alive. In the right hands and the right water, that can translate into quicker line changes, easier swell linking and a board that feels less tied down under your feet.
Why choose the Sonic 18?
- Maximum agility in the range – ideal when quick direction changes and flow matter more than maximum straight-line stability
- Excellent for downwind and technical ocean use – helps the board respond more naturally on bumps and swells
- Useful in shallow or debris-prone water – the smaller size can be an advantage where a bigger fin becomes awkward
- Great for advanced paddlers – particularly those who already know they want a looser, more reactive fin feel
- Strong technical-race option – especially where the course rewards manoeuvrability over pure straight-line tracking
Where it sits in the Black Project fin range
- Choose the Sonic if you prioritise agility, flow and direction changes in downwind or technical conditions
- Choose the Maliko if you want a more forgiving medium step into downwind and open-water use
- Choose the Tiger if you mainly want race speed and buoy-turn performance
- Choose the Ray if you want added stability, tracking and confidence over distance

FAQs
Who is the Sonic 18 best for?It is best for experienced paddlers who already know they want a smaller, looser and more reactive fin for downwinders, technical ocean conditions or faster changes of direction.
Is the Sonic a good choice for improving intermediate paddlers?Usually not as a first step. Most paddlers progressing into open-water use will find the Maliko or Ray easier to handle. The Sonic is more specialised and rewards experience.
Why would someone choose a smaller fin like this?Because in the right conditions a smaller fin can make the board feel faster to redirect, more surfable and easier to link bumps rather than simply track in a straight line.
