The furling drum is on the front of the mast and incorporates a manual override option. Leisure Furl produces eight models for boats from 27-70ft in aluminium or carbon. Average price ex VAT for a 45-footer: US$16,000 (approx £13,000).
Which is better in-mast furling or in boom furling?
The in-boom system is a lot safer and easier to use compared to an in-mast furler. If something goes wrong with the main it will still drop whereas an in-mast sail can cause all sorts of problems if stuck.
What is boom furling?
A furling boom is the way to get the ease of a roller mainsail without having to buy a new mast. Several companies make booms that allow a full-batten main to be rolled into the boom.
What is a lazy jack system for sailing?
Lazy jacks are networks of lines that are rigged along each side of the mainsail from multiple points on the boom or a stack pack to a point on the mast just above the spreaders, at about 60% the mast’s height. Their purpose is to hold the mainsail on top of the boom when it is lowered.
How do you use mast furling?
How To Furl Properly and Prevent Future Jams
- Steer into the wind and fall off to the left a couple of degrees.
- Wrap the boom vang line around a winch and tighten it up a bit.
- Carefully unwrap the mainsheet from the winch and loosen the mainsheet.
- Wrap the outhaul once or twice on a cabin top winch.
How long should my furling line be?
You may lead the furling line halfway down the side deck and directly into the cockpit or almost down to the transom, around a turning block and into the cockpit. As a rule of thumb, we therefore use the boat length, plus 20% as a tail.
What does a boom vang do?
The vang allows vertical adjustment of the boom, and is an extremely important tool to shape the main for speed. Tension the vang to tighten the leech, flatten the sail and bend the mast. Cruisers use the vang to keep the boom from rising when sailing downwind and abraiding the main.
How much does a new boom cost?
Boom lifts are the most expensive type of aerial lift. A new 30′ to 40′ boom lift has an average cost between $30,000 and $75,000 . A 110′ boom lift may cost $100,000+ .
How does a furling system work?
In this roller furling system, the jib is hoisted in a groove, but when not in use is furled around the headstay, rather than lowered. To furl the sail you simply pull on a line that leads from a drum at the base of the jib aft to a winch near the cockpit, which rotates the whole headstay, rolling up the jib.
What is a Dutchman flaking system?
The Dutchman Mainsail Flaking System uses vertical control lines laced through fairleads in the sail to automatically flake the sail. The sail slides up and down on the lines like a window shade. As the sail is dropped, the lines guide the main down to alternate sides of the boom.
What is in mast furling?
What is an in-mast furling mainsail? Unlike a traditional mainsail that is hoisted and doused vertically with a halyard, an in-mast furling mainsail wraps around a tube inside a hollow mast. It is unfurled by an outhaul line and furled back in with a line labelled as the “inhaul.”
Schaefer Marine’s Boom Furling System is the result of years of research, design and sailing. Proven over thousands of miles of use, our unique Patented Articulating Sail Track enables you to reef or furl on any point of sail all from the safety of the cockpit. It is the most advanced solution for mainsail reefing and furling.
What is the difference between in-mast furling and boom-based sails?
Compared with in-mast furling, the boom-based systems weigh less and keep weight lower. Probably the most significant selling point of a sail that lives in the boom, however, is its shape. In-mast furlers require roachless, high-aspect triangles, thus reducing mainsail area, distorting ideal shape, and lessening draft control.
How does pro furl’s Vang work?
The system uses a proprietary vang which is a must, as it is with most of the manufacturers. Pro Furl’s vang is essentially a hard vang (with no adjustment) that kicks the boom up to its ideal furling position. This is a very good concept, the user just eases the main sheet, the sail flogs, and the boom returns to its proper position for furling.
Why Schaefer marine’s boom furlers?
For years, Schaefer Marine has been a leader in headsail furling and reefing systems. Now we bring the same levels of quality and engineering to a new boom furler that finally solves the problems of reefing, lowering and safely stowing the main – even modern, full-batten, high-roach sails built for performance.
