Barton Boomstrut – 7.5m to 9m

Boomstrut 44030 is designed for boats 7.5m – 9m (25ft – 30ft) in length with a maximum boom tip weight of 15kg (33 lbs). Working alongside the existing kicker or rope vang it creates upward lift on the boom to keep the desired sail shape even in light winds. Manufactured with white rods and Spectro Anodised boom and mast fittings. The uplift created means that the boom will not fall onto the boat when the sail is lowered, or the topping lift is released or removed. Suitable to be used with wooden, carbon fibre or aluminium spars.

Part No: 44030 Categories: ,


Six sizes to suit yachts up to 12m/40ft LOA

Patented flexing spring provides fast response and a constant force for vang efficiency

The boomstrut’s lightweight, low-profile design features two flexible coated fibreglass rods which provide the force to support the boom. Pulling the boom down with a conventional kicker causes the Boomstrut to flex; releasing straightens the rods, thereby lifting and supporting the boom.

Maintenance-free, durable design

Eliminates friction and sliding parts.

Improved performance

Less weight and windage.

Easy installation

There’s no need to replace your existing hardware – the Boomstrut mounts independently inside the existing kicking strap tackle.

Simple to follow instructions

The Boomstrut is supplied with complete fitting instructions and more comprehensive details are available here on our website.

Mast fitting can use existing luff groove

To eliminate drilling, the Boomstrut’s mast bracket can be slotted into your mast’s luff groove.

Contoured boom fitting

The Boomstrut’s boom bracket is contoured to fit both round and flat boom profiles.

Carefully designed & constructed

The Barton Boomstrut has been carefully designed and constructed to eliminate sharp edges, minimise parts and provide trouble-free installation and use.

All parts are from high grade stainless steel and black or grey anodised aluminium for good looks and durability. Spare parts available.
