The Differences Between Harken Radial Winches and Harken Performa Winches

Harken have an extensive range of winches which are split into x2 primary ranges: Harken Radial Winches and Harken Performa Winches. In this blog we help you understand the key differences between these Harken Winch ranges and guide you to the right choice for you and your boat’s needs.

The Harken Radial Winches line is loosely described as a cruising range with Harken Performa Winches orientated more to performance projects. Performa bridge the gap to grand prix carbon winches with an approx. 20% price premium over the equivalent Radial size. Both Harken Radial Winches and Harken Performa Winches offer a complete range of options i.e. manual, electric, hydraulic, 1, 2 and 3 speeds.

Harken Radial Winches vs. Harken Performa Winches

So how do the technical specifications of an aluminium size 40, 2-speed, self-tailing, Harken Radial Winches and Harke Performa winches compare?

Hhhmmm…...... on the face of it, there is nothing between them! So, what and where are the differences between these core, Harken winch ranges?

Firstly, if you are looking for Chrome or Brass drums then these are only available in the Harken Radial Winches. Similarly, electric single speed and Rewind (powered in both directions) winches are only under the Harken Radial Winches brand. Harken Performa Winches are also only sold in black aluminium and with 2+ speeds (in the electric/hydraulic ranges).

The key differences between the aluminium Harken Performa Winches vs Harken Radial Winches come down to 4 subtle but important factors.

Sand-blasted drum finish

Like the Harken Radial winch, the Harken Performa winch drum has ribs, designed to drive the line down the drum, when easing, but the primary difference is its sand-blasted finish. This significantly increases the grip on the line which means that higher loads can be held with fewer wraps on the winch, saving race crews valuable seconds.

The downside of this increased grip, is an increase in line abrasion. The covers of modern high-tech lines are specifically designed to manage high levels of abrasion and also the heat generated under higher loads, when easing. However, standard cruising lines on a Harken Performa winch would lead to rapid and excessive amounts of line wear.

Self-tailing jaw

One of the biggest advantages of stronger, higher performance lines is their smaller diameters. The composite self-tailing jaws on the Harken Performa Winches have been made narrower than the Harken Radial Winches range, to ensure they securely grip smaller diameter, stiffer, high-performance lines.

Ball thrust bearings

Whilst the maximum power ratios are the same, for a given size, Performa race winches generally get pushed harder by winch grinders (with a reputation to protect!) and an additional set of Ball Thrust bearings have been added to reduce friction and wear under the highest loads.

Integrated skirt

The final subtle difference is that the Harken Performa winches have an integrated skirt i.e. the drum is a single piece of aluminium and covers the whole base, down to the deck. This means fewer parts and quicker, easier maintenance.

Conclusion on Harken Radial Winches & Harken Performa Winches

Therefore, the distinction is relatively clear-cut between these two Harken winch ranges. It comes down to the lines you are using for your sheets and halyards. If your ropes are double braid polyester or even performance SK78 Dyneema® core, with relatively standard covers, then the Radial winch line will be your go-to selection. It is only when you start getting into optimising your running rigging with hi-tech, specialist, cover materials that you might consider upgrading to the Performa line. Even then you will have to weigh up the improved grip / performance with increased wear and maintenance.
