This has been a lot fun, no? Really, it's funny
. Lagoon develops a hybrid cat that is supposed to help the environment
but then fails to provide adequate sail area to keep her moving in light to moderate air, forcing the use of extra diesel
. Is that good for the environment
? They then design the system so that a huge genset is running nearly all the time. Is that good for the environment?
I blame myself for not spending more time analyzing the electric
drive design. Lagoon had a good track record
with high volume, reasonably sailing cats so I gave them the benefit of the doubt.
Ultimately, there was no way this system could run efficiently. Using a generator
to charge a battery
bank, then using batteries to power motors is very inefficient. Charging
and discharging lead/acids is inefficient. It requires a big genset to run the charing algorithm which ends in a trickle. Then, add losses in the controlled ect., and you have a big loser. It seems the Lagoon engineers, if they used any real engineers, did not think this one through. You then must run your huge generator
for house loads. More help for the environment?
I focused on the use of regeneration to charge batteries which, as far as I know, does not function on current
So, the 420 really isn't a compromise cat. The 420 makes no compromise in the comfort department. The design maximizes internal volume for a given waterline for a given price. It makes no compromise to fuel
efficiency or sailing qualities. I still contend that the diesel 420 should make a fine 6-7 knot
cruiser/motor-sailor for my family
Dave, people with the financial resources to afford a 420 probably don't need a whole lot of sympathy. In the end it's all for fun. I still don't see anything out there with the comfort to price ratio of the 420. The falling dollar has made new cats very expensive to Americans.
The Lagoon 440
, Dean 440, Orana
44 and Moorings 4600 would probably make better world cruisers, but would cost me an extra 100-150K. You gotta love the Fastcat
435. My wife still wants a Lagoon 500. I don't think we could handle that beast.
The manner in which Lagoon, and my broker, left me hanging, and then complained and treated me with contempt when I kept asking questions, stripped me of all loyalty and even the desire to protect my own investment. I am still leaning toward the purchase
, but only because I signed for the initial preproduction price. Lagoon won't be making much, if any, profit on my boat.
