[Electric Boats] Re: Newport 28 conversion

 

Ron,
The Newport 28 is an easy enough boat to convert to electric.  This is what our computer model shows:

Newport 28

Hull Type:             Fin w/spade rudder      

Rig Type:               Masthead Sloop

LOA:                      27.74' / 8.46m   

LWL:                      25.00' / 7.62m

Beam:                   9.50' / 2.90m                       

Displacement:    7000 lbs./ 3175 kgs.       

Ballast:                 3200 lbs. / 1452 kgs.

 

10.0kW Motor Speed & Power Table                          

Kts          Amps    Watts

2.3          6              288

2.9          10           480

3.6          20           960         What a 2 kW genset will drive the boat

4.6          40           1920       A good cruising speed with about 16NM

5.2          60           2880

5.8          80           3840

6.2          100         4800      This is what a 5kW motor will deliver -90% of hull speed

7.0          140         6720       Hull speed with significant reserve

                                9800       Max power

Hull speed           6.70

Lots of boats in San Diego have converted.  You may want to join a presentation that I will be doing  at Chula Vista Marina June 11.  Hopefully one of our three San Diego Newport clients will be there as well.  .
