Why this fear of hybrid diesel-electric propulsion
? These two unsold cats with Solomon drives on them strike me as a bargain.
1. The propulsion
system is just a small element of what is, after all, a sailboat.
2. If the system is working when you buy it, the prospect of it failing is probably no greater than diesel
propulsion and may be considerably less.
3. If the current
owners thought the electric propulsion was such a liability they would retrofit diesel
propulsion themselves to secure a sale. I cannot see it costing as much as $100,000 myself.
4. It should be possible to cure any fault by replacing faulty components like for like, just as you would with diesel propulsion. It is quite likely to be easier.
should be quicker easier and cheaper for a hybrid. Only one diesel engine
, rather than (potentially) three. Access to the genset is likely to be easier and parts
more easy to obtain.
6. Hybrid electric propulsion should be more reliable than diesel. The electric motors are bullet proof industrial units that often operate continuously in hostile environments for tens of thousands of hours without maintenance. The genset to power them are very robust and highly efficient units that are much more reliable, quieter and more economical than marine
diesel engines, which have to operate across a broader range of power demands. The genset and electric motors are cheap
and easy to repair or replace, because they are typically from high volume producers. It is only the specialized control circuitry that may be difficult to repair or replace and this is likely to be solid-state (i.e. highly reliable). In one year's continuous use, covering 12000 miles, we have had no problems with our hybrid diesel-electric system.
Modern cruising catamarans are complicated beasts with a complicated set of interacting systems. Why fear an unfamiliar propulsion system any more than the unfamiliar complexity of say a watermaker
, or navigation
systems, or the 12VDC electrical system
? We've had plenty of problems with other systems, but none with the hybrid diesel-electric propulsion system.
