Rondal design and manufacture booms in both carbon composite and aluminium, with a choice of design/ operating systems: performance boom MKIII, open-ended hydraulic rollaway boom, hydraulic rollaway slab reefing, and Park Avenue.
Performance Boom MKIII
Rondal supplied its first performance boom in the early 1990s. The concept of a boom furling system using an outhaul car to provide foot tensioning for both full and reefed mainsail positions was met with immediate approval by performance-orientated owners.
The first MKII carbon performance boom was installed on SY Visione. Featuring Rondal’s ‘Style to Order’ design options, an open forward end to keep the luff as close to the mast as possible, hydraulic motor located inside the mandrel for weight and styling purposes, and a carbon hydraulic outhaul cylinder, the MKII set new standards in performance and style for boom furling.
With the yachts becoming still larger and the loads becoming higher, we recognised it was time to introduce further market-leading developments.
The new Rondal Performance Boom MKIII will incorporate all the features of its predecessors , our team has developed a new, compact outhaul system that can cope with higher loads and deeper reefs without incurring the weight penalty.
Key features of the Rondal Performance Boom MKIII are:
- Controllable mainsail foot tension, even in reefed positions.
- No guide arms required so no chafe on the sail.
- No load on the mandrel at either full main or reefed positions, resulting in a more stable and powerful mainsail.
- Hydraulic motor installed inside the mandrel at the forward end of the boom.
- Open forward boom end allows the mainsail luff to be as close to the mast as possible.
- Manual backup.
- Style to Order.
Open-ended rollaway booms
The latest development in Rondal boom design and technology is an open-ended rollaway boom powered by a remote hydraulic drive, with a universal linkage to the mandrel. This concept saves weight, allows for easy mainsail furling and avoids the possibility of chafe or other damage to the sail luff. It is also less sensitive to the boom angle when reefing. A worthy successor to the tried-and-tested Rondal standard rollaway boom, the open-ended rollaway boom can be constructed from carbon composite, aluminium extrusions or aluminium plate.
Hydraulic rollaway slab reefing boom
For those with an eye to optimising performance, the Rondal rollaway slab reefing system offers all the quality and reliability of Rondal’s proven boom systems plus the benefits of hydraulic clew outhaul and tack tensioning systems for perfect sail shape and easy adjustment. The engineering design and structure ensures that the full sail load is taken by the boom and not by the mandrel. The system can accommodate a full-roach sail with full-length battens, as required.
Park Avenue boomEspecially suited to the requirements of classic racing yachts such as J-Class, and to yachts preferring flaked sail stowage, Rondal Park Avenue booms offer sleek lines, great structural strength and excellent tuning and reefing capabilities. Rondal has supplied Park Avenue booms for a number of prestige projects.
Principal features of Rondal booms include:
- Style-to-Order styling service to ensure the boom complements the yacht’s design concept as effectively as it fulfils its sail-handling functions.
- The incorporation into the boom construction of any fittings and features required, such as security cameras, dinghy hoist, deck lights and batten-holders. The yacht’s name can also feature on the fine paint finish.
- (Rollaway slab reefing) – the load is taken by the boom, not by the mandrel; halyard, outhaul and vang provide full sail trim at all reef stages.
- Reliable hydraulic motors incorporated with integrated brake system, and easily operated by remote control.
- Extreme reliability backed by Rondal’s renowned service support
