Re: [electricboats] 39' sloop conversion

Matt,
Not so sure you would be satisfied with a 12kW system.  Staying at 48v is safer but you would be better served with a motor that more closely matched the design criteria of the boat builder.  Your original diesel was likely about 30-35hp and if you want similar performance a 20kW motor would be a better match.  This is what our computer model suggests:

38ft displacement sailboat (LOA 39ft – LWL 33ft (estimate) - displacement 18000lbs

• Kts          Watt  (in calm seas)
• 1.9         28
• 2.3         48
• 2.9         96
• 3.7         192
• 4.2         288
• 4.7         384
• 5.0         480
• 5.6         672
• 6.1         816
• 6.6         10080  This is about the max performance of a 10kW motor - 90% of hull speed
• 6.7         11040
• 6.9         12000
• 7.1         12960
• 7.3         13920
• 7.6         15840
• Hull speed           7.70
