Ultralite 310

The perfect combination of lightweight and usability in a small open tender

lightweight and reliable

The Ultralite 310 takes you anywhere you want to go with peace of mind

Ultralite 310

With a weight of 110 lbs, the UL310 model is light and easy to transport, while still having capacity for up to 5 people and a 15hp engine. As their name suggests, the Ultralites’ low weight make them a real alternative for those who may have chosen a soft bottom tender in the past but would prefer the performance of a hard hull. Ultralite tenders are roomy and strong, yet light and easy to transport. These little boats can be launched and recovered by a single person, and are easily transported on a roof rack. The UL hull is built from 2.5mm thick powder coated marine grade aluminum, and the tubes feature1100 Decitex Valmex® PVC or Orca® Hypalon material, cut and assembled to exacting standards. The simple layout of the UL, with an uncluttered design and numerous standard accessories, make the UL series one of the best values in inflatable boats.
