Harken Battcar System

A low-friction Harken CB (captive bearing) Battcar system lets you quickly raise, reef, and douse your full-battened main on all points of sail from the safety of the cockpit. It's a dependable ‘extra hand’ when you’re sailing alone or with inexperienced crew—no matter what the weather.

Installing a new Battcar system is a big project, so if you have any questions, don’t hesitate to email Harken Technical Service or call us at 262-691-3320.

Tech Tips:
Our low-friction Battcars drop the main so fast that we advise a wrap on the halyard winch to slow your takedown and maintain control.

Lazy JacksLazy Jacks contain the main on the boom while dousing to give you
better visibility as you approach the mooring.

Battcar Systems Q&A

9/12/2013

General Information

Harken Battcar Systems let you raise, lower and reef the main instantly from the cockpit even when close reaching in a big breeze. They outperform in-mast or in-boom furling systems at the right price.

Sail AreaWhy choose Battcars instead of in-boom or in-mast furling?
Lower cost: A basic in-boom or in-mast furling system costs four to six times as much as our top-of-the-line Harken Battcar system. With ball-bearing Battcars, you don't need a new boom, running rigging, mast, mainsail, or professional installation. The system is so free of friction that you'll never need an electric winch as long as you can hoist the weight of the sail.

Proven reliability: Battcars have a simple, robust design that withstands years of extreme mainsail loads. Top solo circumnavigators trust these systems to take them around the world.

Sail efficiency: In-boom and in-mast furlers generally require smaller and flatter custom-designed sails so they can roll properly. Battcars let you keep the performance of your existing sail.

Is it safer to sail short or single-handed?
Yes. One of the most difficult things to do safely when sailing alone or shorthanded is reefing the main. This is a two-person job requiring one crew to pull the luff of the sail down while the other eases the halyard. 

You can lower Battcars at any time when the sail is not pressed against the spreaders-in any condition, at any wind angle, and without having someone go forward.

What system size is the right fit? 
Using the table below, select your system based on mainsail area and hull type (boat length is only an estimate). Standard Battcars fit boats from as small as 6.5 meter Minis (21 feet) to as large as 30 meter (100-foot) megayachts. We offer custom systems for yachts over 30 meters (100 feet). 

Harken offers fit kits you can use to make sure you order the slug and track combination that will fit your mast precisely. Ask your Harken representative or rigger for one.

Note: Aluminum web-on headboard plates are available to be used with Battcar systems B (#3861 and #3862) and C (#3876 and #3877). They are easy to install and have radiused edges to protect the sail and use 25 mm (1”) webbing.

How do Battcars make mooring easier?
A Battcar system combined with a set of Lazy Jacks lets you sail almost right up to a mooring. When you release the halyard, the sail drops between the Lazy Jacks into a neat stack and stays on the boom. You'll have excellent visibility as you approach the buoy.

Can Battcars help if a squall comes up with little warning? 
Battcars are perfect for these conditions. If you need to get your sail down in a hurry, let the halyard go and it will drop immediately regardless of the load. We recommend keeping a wrap on the winch to slow the take-down and maintain control.

What modifications need to be made with a full-battened mainsail?
Quick Release Pin (Top); Attaches w/Slugs (bottom) Harken makes cars that accommodate most batten receptacles on the market. All you need is to have your sailmaker add webbing for the intermediate luff cars. 

Is the mainsail easy to remove?
All ball bearing Battcar systems feature captive bearings to make them easy to remove from the mast. No more balls bouncing everywhere. Some System A cars and all System B and C cars have quick-release pins that let you quickly detach the sail without removing the cars.

Harken: Battcar TrackWhat if I don't have a grooved mast?
You can drill and tap your mast to install standard Harken track in place of slug-mount track. Drilling and tapping requires a little more care and expertise to do yourself, but even with professional installation it is still far less expensive than installing an in-boom or in-mast furler.

How can I save money and still get performance using a Battcar system?
We recommend using ball bearing Battcars at the battens and headboard because these carry the highest loads. However, installing less expensive slider cars at the intermediate luff positions will reduce weight, cost, and stack height.
