The range and variety of vangs varies between brands and in this Blog we go through some of the main differences.
Boom Vangs are primarily used to control the leech of the mainsail by restraining the boom from rising when sailing. This helps eliminate excessive sail twist which when left uncontrolled can make your boat unstable with an increased tendency to roll in waves. Sail twist and shape is also a way of getting the best performance out of your boat for the conditions you are sailing in.
Choosing the right boom vang depends on several factors, including your yacht's size, your sailing style, and your specific needs. We know there are many options available, ranging from rigid boom vangs to block and tackle systems. So let's narrow it down a little.
Here are some key considerations to help you make the best choice:
Most common Boom Vangs
Hydraulic Boom Vangs: These use hydraulic pressure to control the boom, providing smooth and powerful adjustments. They are ideal for larger yachts where precise control is essential. Ideal for larger yachts and those requiring precise control. They use hydraulic pressure to adjust the boom, providing smooth and powerful adjustments.
Mechanical Spring Vangs: These vangs use a mechanical spring to support the boom and eliminate the need for a topping lift. They are efficient and faster than hydraulic systems. Suitable for smaller yachts and casual cruisers.
Gas Strut Boom Vangs: Think of a gas strut like those in your office chairs. The Gas Strut is part of the vang and often provides spring-loaded lift and support.
Boat Size
Dinghies: Often utilize a block system or class specific fittings.
Small to Medium Yachts: Mechanical spring vangs or soft vangs are often sufficient. They are easier to install and maintain
Large Yachts: Hydraulic vangs or rigid vangs provide better control and support, especially in heavy weather
Sailing Style
Casual Cruising: A simpler, low-maintenance vang like a mechanical spring vang may be suitable
Racing: A hydraulic or rigid vang offers enhanced control and performance, which is crucial for competitive sailing
Budget
Budget-Friendly Options: Mechanical spring vangs are generally more affordable and easier to maintain
Premium Options: Hydraulic vangs are more expensive but offer superior performance and control
Maintenance and Installation
Ease of Maintenance: Mechanical spring vangs require less maintenance compared to hydraulic systems
Installation: Consider the ease of installation and whether you need professional help. Hydraulic systems are a more complex installation and require a professional rigger. Ensure you are using the correct mast and boom fittings to avoid bending the boom or vang.
Brands we distribute at DeckHardware
Yacht Rods by ForesparSpring-Loaded Mechanical Boom Vangs: Known as Yacht Rods, these provide excellent support for performance cruising and racing. They come in three sizes and are made from high-quality materials like anodized aluminum and stainless steel. The larger size also has options of springs depending on load. An example would include a larger spring to suit a furling boom.
Boomstruts by Barton MarineThese are available in various sizes to suit Off the Beach dinghies [Such as those used for sail training] and yachts up to 12m/40ft LOA. They use a patented flexing fibreglass rod to provide a constant force, ensuring efficient vang performance.
Each type of equipment is designed to offer specific benefits, such as eliminating the need for a topping lift, providing precise control, or supporting the boom in light air conditions. The choice depends on the size of your yacht and your specific sailing requirements.
Bamar have the widest range of Vangs with kicker and mechanical spring, Hydraulic Boom Vangs and the newer E-Vang the electronic boom vang.
Kicker with mechanical spring - It is supplied with an internal steel spring that pushes the boom up.
The range is made up by 5 models in order to be fitted on boats from 30’ to 62’. Its length may be customized onboard when installing it.
This kicker is manufactured in either silver or black anodized aluminum alloy. It is made of two telescopic tubes equipped with special connecting terminals with integrated pulleys that allow for a compact line tackle. The line can be either directed to the cockpit or locked onto the kicker itself by means of an extra tackle with cleat. The spring allows you to adjust the kicker thrust by rotating the upper tube/terminal.
The first patented Electronic Boom Vang
E-Vang - Electric boom vangs can be made in multiple sizes with different dynamic pull to cover all needs. The units are manufactured with CNC machines from certified solid bars of material. Bodies are made in anodized aluminium alloy and studs/pins are made in special steel. Electric motors are combined with planetary gearboxes for maximum efficiency with minimum electric absorption.
Vang cylinders are equipped with a pressure rod release. Inert gas pressure is charged through a “pneumatic” valve located on the cylinder body, near to the boom-side vang terminal.
Gas pressure is to be adjusted depending both on the release speed you wish, and on the thrust needed to contrast the weight of the boom.
The system is equipped with a mechanical valve to exclude the gas-loading pin and grant pressure holds in time.
Block Vang Systems
We also have some block vang systems premade and available from Barton Marine and Schaefer Marine.
Both Brands block vang systems can also be used as a preventer.
Barton have two great product sheets with even more information on their Boom Vang Systems.
For Dinghies like the Finn and OK we have the Allen V2 Lever
The V2 Vang Lever is lightweight, strong and stylish. The large window cut-outs reduce overall weight whilst retaining maximum strength where it is needed.
Four large custom made sheaves guide the primary vang control line around the central axle. The large radius of these sheaves helps reduce loading and friction. Making the V2 Vang easier to control when pulling or easing the control line.
Allen Vang KingThe Vang King is not just a gas strut; it’s a game-changer in vang control systems for keelboats up to 26ft. Designed to serve as a boom support system, the Vang King seamlessly integrates with a purchase system to deliver unmatched control of your mainsail vang settings.
In light winds, the Vang King will hold the boom up which will reduce the unwanted weight on the mainsail leech and thus result in a better sail shape and more speed. Whether you’re cruising or racing, the Vang King ensures optimal performance in every sailing condition.
By considering these factors, you can choose a boom vang that best suits your yacht and sailing needs.
