Except for those prefabricated propellers which Henley’s distribute, a detailed propeller drawing is provided to our customers in order to give the man idea on what will be the profile of their custom made propeller. Henley’s will specify one of these custom designs to suit your vessel.
Why should you choose Henley’s Propellers?
Data used for prop selection is supplied by our customer on a Propeller Specification Form. This information is firstly compared to Henley’s vast database of proven designs, and then entered into intricate computer software programmes insuring the best possible selection for the customer.
We then use this propeller selection in a Propeller Drawing Program which is a parametric design/drafting tool for the preparation of detailed and dimensioned propeller drawings. The designs made with the use of this equipment are then transformed into patterns, castings and a personalised "custom built" boat propeller. To ensure the propeller design is maintained and that the propeller is manufactured in conformity with ISO 484/2 Class 2, 1 or S standards, Henley’s have invested 20 years ago in Electronic Propeller Scanning equipment.
This allows us to measure a propeller and to produce reports on the quality of the propeller to a set standard that is recognised World-wide.
This technology also allow us to repair our props to the original design and or repair props of various designers to a known standard of tolerance which produces the best efficiency’s. This gives Henley’s a distinctive advantage over others, as we are able to control the design, manufacture and the after care of Henley’s propellers.
Henley’s is also involved in a worldwide network of propeller technicians operating similar equipment, to whom we will be able to forward your propeller data and they would be able to extend the Henley’s care you deserve.
