The '''29er''' is a two-person high performance [[Engineering:Skiff (sailing)|sailing skiff]] designed by Julian Bethwaite and first produced in 1998. Derived from the Olympic class [[Engineering:49er (dinghy)|49er]] class, it is raced in the ISAF Youth Sailing World Championships.<ref>{{cite web|title=Bethwaite Design|url=http://www.bethwaite.com/|access-date=30 October 2016|archive-date=15 June 2006|archive-url=https://web.archive.org/web/20060615161912/http://www.bethwaite.com/|url-status=dead}}</ref> The 29er is able to reach high speeds fairly quickly by having a sleek and hydrodynamic [[Engineering:Hull (watercraft)|hull]] and will often exceed the wind speed when planing both up and downwind.

==Background==
[[File:29er dinghy sailboat 7383.jpg|thumb|left|29er]]
The 29er class is targeted at youth, especially those training to sail the larger Olympic [[Engineering:49er (dinghy)|49er]].   The Youth Sailing World Championships{{Citation needed|reason=When? is it still current?|date=October 2016}} has adopted it to replace the [[Engineering:Laser 2|Laser 2]] - which was designed by Julian Bethwaite's father Frank.

The 29er has two sailors, one on trapeze. The rig features a fractional [[Engineering:Asymmetrical spinnaker|asymmetrical spinnaker]]; a self-tacking jib decreases the work load of the crew, making maneuvers  more efficient and freeing the crew to take the mainsheet upwind and on two-sail reaches. The spinnaker rigging set-up challenges crews to be fit and coordinated, and maneuvers in the boat require athleticism due to its lack of inherent stability and the high speed with which the fully battened mainsail and jib power up. {{Citation needed|reason=link to class rules?|date=October 2016}}

The hull construction is of fibreglass-reinforced polyester in a foam sandwich layout. The fully battened mainsail and jib are made from a transparent Mylar laminate with orange or red Dacron trimming, while the spinnaker is manufactured from ripstop Nylon. The mast is in three parts - an aluminium bottom and middle section, with a polyester-fiberglass composite tip to increase mast bend and decrease both overall weight, and the capsizing moment a heavy mast tip can generate. Foils are aluminium or fibreglass. {{Citation needed|reason=link to class rules?|date=October 2016}}

The class has shown large popularity in Oceania with over 700 registered boats out of the 7000 registered worldwide<ref>{{Cite web |title=Home |url=https://openskiff.org.au/ |access-date=2022-05-03 |website=O'pen Skiff Sailing Australia |language=en-US}}</ref>

==29er XX and XS==

Bethwaite and Jen Glass have also designed the [[Engineering:29erXX|29erXX]], a twin trapeze derivative of the 29er. It uses the same hull with some minor changes such as an extended gunwale and a rudder gantry, with a larger rig that includes a square-top main and masthead asymmetric spinnaker. The class became an International Sailing Federation recognised class in its own right in 2010. {{citation needed|date=October 2016}}

In late 2012 Bethwaite announced another new version, the 29erXS, aimed at younger and/or lighter sailors. The XS features a similar rig to the XX, but of smaller size fitted to a standard 29er hull and employing a single trapeze.  The main being 4.29sqm and the jib 2.13sqm, the spinnaker is similarly downsized.<ref>{{cite web |last1=Bethwaite |first1=Julian |title=29er XS sail area |url=https://forums.sailinganarchy.com/index.php?/topic/215963-29er-xs-rig-at-club-level-an-experiment-begins/&do=findComment&comment=7091605 |website=Sailing Anarchy |access-date=7 July 2020}}</ref> The intention is that sailors can upgrade the rig when they are ready to move to full sized sails, and keep the hull, which will remain standard across all 29er variants.{{fact|date=January 2024}}
