Karver is expanding its line of hooks
With METSTRADE 2026 just a few days away, Karver has announced an agreement with Alphalock to take over its operations and utilize its magnetic locking technology.
The transaction includes the rights necessary to use Alphalock's patents and know-how, as well as the transfer of technical documentation and business relationships. The financial terms were not disclosed.
For Karver, the goal is to round out a product line that already includes internal and external hooks, locks for furling systems, reefing hooks, and mainsail locking systems.
A magnetic technology developed by Eric Hall
Founded by Eric Hall, who also founded Hall Spars, Alphalock specializes in automatic halyard locking mechanisms.
Its unique feature lies in the use of magnetic assistance to control the mechanism. According to the manufacturer, the mechanism has only one moving part and operates without a spring or trigger pin.
A hook allows the force exerted by a sail to be transferred directly to the mast or a point on the rigging, rather than having the entire load borne by the halyard. This principle can, in particular, limit the effects of rope stretch and make it easier to maintain sail settings.
Reducing the number of parts is a key factor in mechanical simplicity. However, the press release does not provide test results that would allow for a comparison of this technology's reliability with that of other systems.
Applications for masts, headsails, and reefing systems
Karver plans to develop several applications for this technology: locks mounted inside or outside the mast, locking mechanisms for headsail halyards, tack points, and reefing systems.
The manufacturer also plans to work on compatibility with Antal equipment, particularly mainsail tracks and trolleys.
This complementary nature could be of interest to shipyards, riggers, and system integrators, who must ensure consistency in equipment and load transfer. The specific products involved and their release schedule have yet to be determined.
A Phased Integration Presented at METSTRADE
Karver announces that Alphalock products will be gradually added to its catalog, with continuity expected in terms of supply, technical support, and sales follow-up.
Future developments that utilize this technology will bear the "Powered by Alphalock" label.
The company will present this collaboration at the METSTRADE in Amsterdam, November 17?19, 2026 . This event should provide more information about the first products involved and how they will be integrated into existing product lines.
For Karver, the challenge will be to transform this acquisition of expertise into a cohesive line of locking systems, tailored to the demands of ocean racing as well as the needs of recreational boating and large vessels.
