Future of pods

I think possibly a touch optimistic on time line. Advances and changes are moving at 1/2 the speed at which they did prior to 2009. But I would like to see up to 2000 hp pods and what that can do for fuel efficiency and speed in the future.

I also think as battery technology keeps increasing by leaps and bounds that we will see a lot of diesel electric in my lifetime on the yachts.

The biggest disadvantage with going bigger is Neither cummins nor Volvo have large enough engines for the Zues or IPS systems. So that means mating a ZF pod (or other) to a different manufacturers engine such as Cat, MTU, MAN. Well if you have a warranty issue and it's in that grey area. Both manufacturers punt the expense and who is going to fix it football back and forth. I was involved in one boat where that happened, both CAT and ZF kept saying it's not on our side, it's on your side. It was a serious vibration issue and it turns out after 6 weeks of this that it was the carbon fiber jackshaft between the pod and the engine, and it shredded. But with Zues or IPS ALL of your maintanence and warranty is with 1 manufacturer.

Pods are being used lately by all of the new cruise ships so I don't think there is a limitation to their size or what makes them feasible or not feasible when it comes to size of the yacht. Although certain types of hull designs might not derange any benefit from them.

The JMS, ZF and other systems utilizing shafts and a bow thruster, aren't anywhere near the finesse and maneuverability of the pods and create their own issues. Now you have to have and rely on a way oversized bow thruster, the weight of it and it's batteries or hydraulic system, and the sheer noise of it as well as the balance issues the weight and placement of it makes. Then can or can't the bow thruster stay running without running out of battery or overheating if you're using it for a prolonged period of time. I'd rather not even have it. I can use the gears and bow thruster just fine on my own. Some lesser Captains and owners, it probably is a benefit.

Yep, Real drivers don't need no stinking fancy joysticks or thrusters.....

With the joystick system, you do not really know how much the system is using the bow thruster on most boats.

Most owners and some Captains are totally lost if their bow thruster goes down and don't know how to dock or maneuver without it.

Which is one advantage of pods for those of us new to driving bigger boats. We can use the joy stick to park while we practice using gears to maneuver. Each helmsman worthy of the boat will be able to do both. But what a joy to be able to learn with a nice joy stick as a back up to keep everyone happier in the mean time.
I realize not all skippers will take the time to enjoy learning how to drive with gears only but I can assure you I am much more comfortable moving around 40,000 lbs in tight spaces, in current and windage with a joy stick as I learn.

As for the OP questions:
1. Sportfisher's will likely continue with more use of pods, speed is good, fuel economy is good, less exhaust when fishing

2. More exp. cruisers into pods, for sure, no reason not to, I see down to 37 feet or so.

3. Up scale Lazzara/Sunseeker/Riva I think Mr. Lazzara says yes

4. a lot like question 3 to me.

5. Hinkley not likely they like the jet thingy, but MJM is pod so lobster type cruisers are going that way.

6. Pershing, never, rooster tails never lie.

7. 80-130 foot yachts, if bigger twins evolve then yes, it seems that not many folks seem to own/operate this size and maybe pods can affect that???

8. Tugs, not likely as they seem to like keels, skeg hung rudder and stuff to protect gear.

9. trips and quads, I don't think so as that is such a Verado and 557 thing. If you can't see my four ips pods you may just think I have only two. I can't imagine wanting to maintain three or four engines and drive units instead of two bigger ones.

10. 25-30 foot pods vs. outdrives... I don't think so, trailering is much more doable with outdrives and outboards that go up. Plus lot's of these boats like to beach.

For what it is worth...

Pods on a tug will be around soon if not already.
Kort nozzles are in use and I remember a jet on one (like an underwater gun turret). Not IPS or Zuse, but a ships pod and probably electric.

None of the statement above is based on truth. Zues have the propellors rear facing for starters. The diameter of the props on pod boats are half the diameter of traditional props. Pod boats do not have thrusters, everything is done with the pods. Oversteer???? If you're coming into a slip you'd generally be using the joystick.....even if you use the gears, they still don't oversteer etc.

Good data Karo1776.
Thx

To add to Karo's info. The ZF lack a little finesse in maneuvering compared to both Zues and IPS. They are still very good, but don't quite have the finesse and would rate them 8/10 versus 10/10 (zues/ips) for dockside maneuvering. Also given all 3 of them, how they handle varies a bit from boat manufacturer to boat manufacturer, depending on how much time the manufacturer spent on sea-trialing and tuning the software.

Well, bow thrusters are showing up more and more on pod-driven boats, particularly over fifty feet. Personally, I almost always used sticks exclusively at idle speeds on my Zeus boat until getting into truly close quarters. Regardless of my abilities with traditional propulsion I always used the joystick when docking because of the precision it offered and yes - working the sticks on a pod boat vs its traditionally driven counterpart will yield a much different experience because of the size of the wheels and other factors. Oversteer was never a factor. What most people new to joystick docking have to learn is the art of finesse and, perhaps most importantly, how to dock that specific boat should your joystick fail. It will not handle quite like straight or V-drives. I was fortunate to never have had a failure but know people who have and I spent a lot of time at the docks getting to know the boat's handling characteristics in close quarters with just the sticks/sticks and wheel - remember - pods provide vectored thrust and the wheel will turn your boat at idle speed in a way that standard rudders can't.

Joystick docking is, understandably, often one of the first topics of conversation when pods come up. But there are benefits that get far less attention which I have found to be among the most appealing components of owning a pod-driven boat including the relative sound level/vibration reductions, with Zeus - Precision Pilot - their proprietary auto pilot system that I find an absolute joy to use and also with Zeus - Skyhook - their dynamic positioning system I never want to be without again in one form or another. DPS is obviously available with with other propulsion setups but, at least in my case, I have found the system integrated with my pod drives to work flawlessly, even in some pretty unforgiving situations without any thrusters working overtime.

It just wasn't fast enough. There also wasn't any advantage to it as the outboard boat was almost as efficient.

Pods really shine when they replace a twin inboard shaft boat.
