CRAZY 50kts+! Jet Drive Luxury Day Boat - Centouno Navi Vespro 

Thanks, will do!

I understand that a lot of aerodynamics went into that roof design so that may complicate air flow

I appreciate that. A lot of work goes into these vids so comments like this keep me motivated!

I am far from an expert but am going to disagree that jets are not the best for low speed manoeuvrability. In my limited experience, a jet ski even without a bucket is much easier to change direction at low speed vs even an outboard and way more vs any rudder system. Some of the most manoeuvrable boats are jet drive for that reason like pilot boats and tugs. A jet does not need to be moving in water to get any directional control over a rudder like other traditional drives excluding IPS or Azipod type drives. The force, and it's direction is contained entirely in the jet itself and does not need it's outlet in the water to be fully effective. The force comes from the velocity change of the water. Pivot the chamber and you pivot the force. What you do need is volume. So low engine speed results in low authority of control. With a bucket you can keep your engine speed and the volume or flow up to where the maneuverability is unmatched. You can have neutral handling at full engine speed and not have to reduce rpm then change gears. Twin jets with buckets is instant response to inputs and is very precise. See Hinkley boats as an example of ease of low speed control. The down side of big power jet drives is it takes a ton of volume to go with the outlet sized to match the power so you do not get an big increase in range at low speed because you end up as pump drive untill the flow is restricted to get the velocity change. This is mostly just conjecture from what I have picked up, so I hope someone else can weigh in and break the tie.

@@tomconnors8165 You aren't wrong, we are talking about significantly different scales of watercraft and jet designs. My experience is from very large boats outfitted with jet drives (much larger than 55') .. which is why I gave a very simplistic and general overview. I know guys with twin jet Yamaha center consoles that have modified their jets simply because of the response at low engine RPM.

I’m no expert with jets so will listen to you guys and just drive as many jet drives I can get my hands on now to see what we can learn

Yeah I don’t know how to fix that yet. Some internal lights really screw with the footage quality

Yes this is the baby and Marco has some pretty cool plans! I did introduce myself to Nick a while back offering to share my drone footage with him but I probably came across as a weird Aussie bloke so it didn’t go anywhere. He’s doing great stuff!

I found the horn useful as a navigation aid. Correct… so many cool boats I’ve actually left Australia permanently now.

Yep 👍

Check out the link to their website. I think with top speeds of 56kts then bow seating gets complicated. This design is designed and tested for aerodynamics

I think to be fair most people using this boat in Europe will be on deck. She's very much a fancy day boat

@@BoatLife_DansBoatLife Good point my friend.

Haha… well the new Sunseeker dealers for Australia and Asia are in contact so it will happen now. Previous dealers I never had any luck communicating with them

Haha seems to be dividing people that horn on the bow. I’m pro horn personally… i found it useful as a navigation aid

Haha noted! I just had to improvise as we were short on time

They do have a special sauce that nobody seems to be able to replicate. It’s a way that they analyse style with everything they do

I think the idea behind technology like the joystick is to open boats like this up to a wider market. Most of the guy who can afford one of these will not have experience driving them so it makes good business sense to allow them to master it quickly. Otherwise you’re limiting your market to commercial, military etc

@@BoatLife_DansBoatLife Agreed, but I still maintain the skipper of a boat should be able to handle it competently using the primary controls. A guy who can afford a boat like this, might not want to get burdened with a court case, when his skipper damages another vessel or person, because he couldn't manoeuvre it adequately.
