My comment on the practicality of electric vs diesel as it relates to commercial operators has to do with the cost of diesel fuel for a year. Lets say your boat goes out 20 days a month and uses 5 gal of diesel per. At $4.00 a gallon that's roughly $5000 a year for fuel. The Torqueedo set up, not counting initial cost of say $10,000 still must be charged up with generator or using shore power at night rates. Sure, on a good day you can recapture some juice with renewables but realistically only a fraction of what you need and not dependably. So I can see where an operator might see a break even at 4 years and then start to save money, only to ( supposedly)
Need a new battery bank at 8 years. However, in your charter business electric propulsion might be a marketing strategy that would allow you to book a different clientele that would pay more thus affecting your bottom line to the extent where it would be a win-win.

Hi AllThanks for the feedback.Here is a bit more info hope this helpsI would be looking to get about 2 hours from battery as mostly I am sailing,the battery's must recharge as I sailI obviously need a generator to recharge when not sailing or no windAnd for domestic powerThe alternative is buying both a Diesel engine and a generatorWhy would a commercial outfit be different , we live on Desi 24/7I don't believe weight will be an issue as Desi weighs 30 tonnes and at the moment we carry 1000 ltrs in two tanks one of which I would convert to battery space
