Thanks guys for the input, maybe it's the expectations, might be the hopes of a new technology. Brett the link was great to read as was the rest of the posts in the link to "420 owners" but as you probably know, 90% of the posts there were either owners waiting for their boats and complaining, people who new little of the tech and complaining, bashers just bashing, and then the 10% who had hopes that this may be an improvement to their sailing experience.
I won't by a hybrid car because my feelings are the manufactures are building something to fill a gap. I don't have expectations that the 100% electric car is in the near future however a commuter car for lets say 100 miles on a charge is possible and a car I could use.
I don't have any hopes (or desire at this time)of sailing around the world on zero dino fuel
. I want to feel comfortable on a week or 2 sail knowing I have a system that is dependable and low maintenance
. So lets look at it from this perspective.
Brett, you mentioned sailing a 410. You seemed to have enjoyed the sailing and I'm wondering how the boat felt compared to a non E cat of similar size. I'm not concerned about a 1/2 knot
difference but the balance and "feel" of the boat just under sail. I would hope I would be sailing 80% of the time and the use of the genset would be limited to the entry/exit of the slip. If under power and the genset is running for 800 nm I would think that the "green" effect would still be high compared to 3 diesels running but even if it was the same I'd be ok at this time with that.
It seems that the big maintenance
replacement item on electrics are the batteries. The AGM
4D batteries run about $400 a piece and you got 12= $4,800 about every 5 years or a budget
of $1k a year. From what I read here the maintenance costs of diesels is much higher than that. In 5 years the technology of batteries will be improved drastically. The Engines will still be the same ones in 5 years (I would hope) so the cost of maintenance will stay the same or increase. Yes this doesn't take into consideration maintenance on the other controllers or the genset but these will improve as well so upgrading is still a factor.
Redundancy of the diesel engines, the ability to run still on 1 motor
is a huge plus but there are still a lot of ways you can loose both engines.
If you take out the factor that you aren't going to generate the full replacement energy with no genset you use at this point is the Ecat still better than a couple of diesels dollar for dollar?
No where do I see a list of the negatives of an Ecat spelled out compared to the typical cat if you take the hype out of the technology. Yes there was a lot of things said about the wave of the future but what if you look at the positives compared to the existing systems? Are they that bad?
