Rapid Turn Around Service

Historically, when it came to the design and production of propellers, you could have speed of delivery or high quality, not both. Rapid production meant opting for an off the shelf pattern that was considered a ‘close match’ to your vessel. The notable downside to this approach is that the propellers aren’t QUALITY WITH AGILITY TO MEET THE NEEDS OF THE INDUSTRY designed for a specific boat, or its requirements, and therefore are not optimised for performance or efficiency. This could cost you in multiple ways, including top speed, fuel burn, ride comfort and longevity. Alternatively, if you required a bespoke, fully optimised, Class S propeller, you would likely be waiting eight weeks or more before it was shipped. Thankfully, this is no longer the case.
