Compare a compact fin profile with the Moloko Flexi Thruster US Fin. Its plastic construction has some flex, with a listed depth of 3.5 inches and an 8-inch base length. The measurements give you a starting point; confirm the base and fixing against the board you use.
Why choose it?
- Compact published depth of 3.5 inches.
- Plastic construction with some flex.
- Clearly identified base length for comparison.
How the details help
A small depth means less lateral area than a larger fin of similar shape. That trade-off matters if you are considering it in place of a larger centre fin. The shallow profile should not be treated as proof that a river or other route is suitable.

Choosing and using it
Check whether your intended setup calls for this fin format, then verify the base and securing arrangement. Ask before substituting it for an existing centre fin with different dimensions.
Questions before you buy
Does the base need less room because the fin is short?
No. The published base is 8 inches long; depth and base are separate measurements.
Will it provide the same feel as a deeper fin?
Do not assume that. Changing fin area and shape changes the setup and needs an appropriate comparison.
