There is one propeller for each sailor, or for each way of sailing

A propeller is possibly one of the most important parts of a ship, because it ultimately determines the speed that will get, and the efficiency it will obtain. So, we can affirm, the propeller must be taken very seriously. Dozens of books have been written on this subject, but the experience on the study and know-how on the manufacture are the bases for a final good performance.

The propeller must be calculated to obtain the best efficiency from the characterisics of each case and ship: engine power, gearbox ratio, type of ship, waterline length, stern post dimensions, cruising rate you wish to sail, etc. That's the reason why we can say this is a business for specialists that are able to study and manufacture a PROPELLER FOR EACH CUSTOMER.
