The owner of the motorboat in our marina next to our Skoota asked us to move as far from his boat as possible as he said he was very un-manouverable at slow speeds as he didnt have a bow thruster and couldnt easily.

Single engine catamaran cavitation. The boat did exhibit some cavitation actually ventilation when traveling with a sharp following sea at planing speed. Both of the catamarans have a head in the console which is unusual in a center console catamaran and both self bailing which was really important to us. Make sure the Permatrim is straight.

It was a little unnerving at first as the engine rpm would rise and fall slightly but did not hurt the boats performance. It makes sense to have a single engine centrally mounted. The Permatrim should be mounted as close to the raised section as possible without lifting the Permatrim off of the AV plate.

The boat with twin Suzuki 115s and standard features with trailer can be had for around 65000-68000. Well that was my idea on the high speed catamaran. Single engine cats tend to have ventilation issues because of the style of the hull and engine location.

So a base boat increase plus the premium for the Yamahas probably looking at 70k. Raises clear of the water for sailing. One was a single engine 19 ft.

With a single outboard engine mounted in the center of the tunnel section aerated water that moves through the tunnel travels past the propeller. Tideline has solved the standard knock against single engine catscavitation as air gets trapped in the tunnel and lifts the enginewith a skeg in front of the motor to block air flow longer. Cavitation single-engine powered catamarans all seem to suffer from to various degrees.

That motion makes the boats bow naturally move left and the stern move right even when the outboard is perfectly aligned. Outboard very reliable economical 4 stroke outboard is mounted in a cockpit well safe from swamping and cavitation. Ive heard that a hydraulic jack plate which would allow the engine to be lowered in a following sea would reduce cavitation even further.
