Choosing the Right Selden Rodkicker: A Guide for Cruisers and Racers

Whether you're a seasoned sailor or a weekend cruiser, upgrading to a Selden Rodkicker can dramatically improve your sail handling and boom control. But with multiple models and configurations available, how do you choose the right one for your boat?

This guide will walk you through what a Rodkicker does, why it matters, and how to select the perfect model for your rig.

What Is a Rodkicker?

A Rodkicker is a rigid boom support system that replaces or supplements the traditional topping lift. Manufactured by Selden Mast, the Rodkicker serves two main purposes:

• Supports the boom when the sail is lowered
• Controls leech tension and sail shape by resisting downward force on the boom

When fitted with a gas spring, it also lifts the boom automatically when the mainsail is dropped—making reefing and flaking much easier.

Benefits of a Selden Rodkicker

• Eliminates the need for a topping lift

• Improves mainsail shape by controlling boom height
• Makes reefing safer and easier, especially when sailing short-handed
• Reduces wear on the sail and rigging
• Sleek, low-maintenance design

How to Choose the Right Rodkicker

Selden offers several Rodkicker models, each designed for a specific range of boat sizes and rig loads. The key factors to consider are:

1. Boat Displacement

Heavier boats require stronger Rodkickers to support the boom and resist compression loads.

2. Boom Length and Height

The vertical distance between the gooseneck and the boom when the sail is down determines whether you need a standard or long version.

3. Righting Moment

This is a measure of your boat’s resistance to heeling. Selden uses this to recommend the appropriate Rodkicker strength.

Example: A Westerly Corsair 36 (displacement ~6 tonnes) would typically use a Type 10 Rodkicker, possibly with a gas spring and long version if the boom sits high.

Gas Spring Options

Selden Rodkickers can be fitted with an internal gas spring to lift the boom automatically. Choose based on boom weight and sail handling needs:

• No Spring: Basic support only
• Normal Spring: Standard boom and sail
• Hard Spring: Heavier booms or stack packs
• Extra Hard: Large booms or offshore rigs

Installation Tips

• Use Selden’s mounting brackets for a secure fit to mast and boom
• Ensure the Rodkicker is installed with the correct angle and compression preload
• Periodically inspect for wear at pivot points and replace buffer bearings as needed

Final Thoughts

A Selden Rodkicker is a smart upgrade for any sailor looking to improve boom control, simplify reefing, and reduce reliance on a topping lift. By choosing the right model for your boat’s size and rig, you’ll enjoy smoother sail handling and a more efficient sailing experience.
