The '''Laser 4.7''' or '''ILCA 4''' is a [[one-design]] dinghy class in the [[Laser (dinghy)|Laser]] series and is a one-design class of sailboat. All Lasers are built to the same specifications. The Laser is 4.06 m (13&nbsp;ft 10 in) long, with a [[waterline length]] of 3.81 m (12&nbsp;ft 6 in). The hull weight is 59&nbsp;kg (130&nbsp;lb). The boat is manufactured by ILCA and World Sailing approved builders.

Lasers are [[cat-rigged]], meaning they have only one sail. The 4.7 uses the same hull and top mast section as the [[Laser (dinghy)|Laser]], but has a different, shorter bottom mast section as well as a smaller sail. The bottom mast section is pre-bent which effectively reduces the power of the rig, and the sail is only 4.7 square meters, as opposed to 7 for the [[Laser (dinghy)|Laser Standard]] or 5.7 for the [[Laser Radial]]. (ILCA 6) The smaller sail means that the 4.7 can be easily sailed by sailors weighing only 50–65&nbsp;kg (110–145&nbsp;lb), though this boat can still be sailed competitively at all levels under and over the ideal weights.<ref>{{cite web |url=http://www.laserperformance.com/laser-47/home |title=LaserPerformance - Home |access-date=2014-04-19 |url-status=dead |archive-url=https://web.archive.org/web/20140404114156/http://www.laserperformance.com/laser-47/home |archive-date=2014-04-04 }}</ref><ref>{{Cite web|url=https://laser.org/|title=Home - ILCA North America|website=laser.org}}</ref>

==Description==
The Laser 4.7 has been increasing in popularity around the world since the late 1990s. In some areas it is less popular than the [[Byte (dinghy)|Byte]] dinghy, a very similar class also designed as a youth single-handed racing trainer, but the interchangeability of the rigs of the Laser series has always made them popular. It is popular among youth sailors graduating from the [[Optimist dinghy|Optimist]] sailing dinghy and also the [[Topper (dinghy)]], and many 4.7 sailors graduate to the Laser Radial (ILCA 6) as they progress their sailing abilitie and size. The Laser 4.7 is also sailed widely at a club level as the smaller rig suits the more inexperienced sailors.
