Proper manufacturing techniques are the only way to assure the design is executed to the highest level of accuracy.

PATTERN - The first step is to transform the design into a pattern. We use state of the art CNC milling machines along with our patented computer software to score patterns to the highest degree of accuracy.

MOLDS - The patterns are then used to precisely manufacture our sand molds used during the casting process. Our Pro series molds are manufactured with Chemically Bonded Sand also referred to as “No-bake” sand. It consist of a combination of high grade silica sand and chemical bonding agents.

Hub Boring - Propellers are bored to accurate measurements using Ahoy’s computer driven CNC milling machines according to SAE J755 and ISO 4566 standards. Tapers are available in 1:16 and 1:10 ratios.

Dynamic Balancing - All propellers are balanced using Ahoy’s high speed digital balancer which allows your propellers to be installed on your vessel immediately upon delivery. All propellers are dynamically balanced according to the ISO 1940/1 standards of G 6.3 or G2.5 (residual balance mass).

Finishing - All propellers are finished using our exclusive software and our patented measuring instruments and inspection equipment. We have designed the worlds first 6D-axial inspection machine. Its basic functions include: scanning and analyzing pitch, expanded area, thickness, prop angle of elevation and the deviation angle among blades. It can also measure a single blade of CCP. It's the only prop inspection instrument on the market which can digitally measure the thickness of props in a one step process.

Our Pro Series propellers are finished to standards of Class S and Class I by computer driven CNC milling machines which completes the propeller making process in accordance with the internationally used ISO 484/ 2-1981 Norm.

Our standard propellers are hand finished by our team of highly trained technicians to ISO 484/ 2-1981 Norm. of between Class II and Class III.
