Jet Drive vs Sterndrive?

Muscling their way onto the market in the early ’90s, “sport jets” were dismissed as little more than toys, quick and agile playthings, scoffed at by serious boaters. They peaked quickly and then vanished just as fast.

But a funny thing happened on the way to obscurity. Sea-Doo and Yamaha developed bigger, more versatile offerings. Today jet-powered runabouts are the best-selling models in the 24- and 21-foot segments.

To find out why jets are giving sterndrives a run for their money, and to determine if jets are suitable propulsion for experienced boaters, we pitted a Sea-Doo 210 Challenger S featuring a single 255 hp supercharged high-output Rotax jetdrive against a Chaparral H2O 19 Sport with a 220 hp MerCruiser sterndrive and put them through their paces.

Aprobado el uso de Hamilton Jetdrives para Cartagena

07 Agosto 2012, Florida, EE.UU.Yamaha J105 Jet Drive Cowling

Mar y Sol orgullosamente presenta barcos estilo catamarán con propulsión de chorro.

Gracias al interés del público de Cartagena y la necesidad de tener barcos cómodos con las ciénagas comunes en esa parte de Colombia, presentamos lo que posiblemente sea el primer catamarán con propulsión de chorro.

El uso de impulsores de chorro estilo Hamilton (conocidos como impulsores «jetdrive» en inglés) está aprobado para el uso con varios barcos con motores fuera de borda.

Los barcos de TwinVee, fabricados con materiales sintéticos ligeros calan muy poca agua por su diseño, sin embargo las ciénagas son poco profunda y suelen tener obstáculos semi-sumergidos.  Una colisión a velocidad con una helíce típicamente resulta con una o varias hélices dañadas.

El jetdrive proporciona una aceleración superior a la propulsión con hélices, y ofrece varias cualidades deseables para operación en las ciénagas.

  1. la unidad de propulsión cala menos agua que el casco de la embarcación
  2. el barco puede ejecutar maniobras con mayor facilidad
  3. no tiene hélice expuesto
  4. estorbar menos el fondo

Conversaciones con los fabricantes de los motores y de los barcos resultaron en la aprobación de varias combinaciones de barco y motor.

Para los que tienen o desean propulsión convencional, Mar y Sol también ofrece hélices de fabricación sintética diseñadas específicamente para colisiones subacuáticas.

Para mayor información favor de ponerse en contacto con Mar y Sol de Colombia, llamando al +57 (314) 541-3327; o bien enviando un correo a ventas@marysoldecolombia.com

Jet Drive vs Sterndrive

To prop or not to prop, that is the question.

Muscling their way onto the market in the early ’90s, “sport jets” were dismissed as little more than toys, quick and agile playthings, scoffed at by serious boaters. They peaked quickly and then vanished just as fast.

But a funny thing happened on the way to obscurity. Sea-Doo and Yamaha developed bigger, more versatile offerings. Today jet-powered runabouts are the best-selling models in the 24- and 21-foot segments.
