If the boat is a Bombay Clipper Pilothouse, the dimensions are as follows:
Hull Type: Long Keel
Rig Type: Masthead Sloop
LOA: 31.00' / 9.45m
LWL: 25.75' / 7.85m
Beam: 11.50' / 3.51m
Draft (max.) 3.50' / 1.07m
Disp. 12250 lbs./ 5557 kgs.
Ballast: 4000 lbs. / 1814 kgs.
This is the speed and power table for the boat
Kts Amps Watts
2.4 10 480
3.1 20 960
3.9 40 1920
4.4 60 2880
4.9 80 3840
5.6 120 5760
6.6 190 9120
7.0 240 11520
7.6 300 14400
Hull speed 6.80
You would need a 15kW motor to match the diesel power in the boat and to get the boat to hull speed with authority. With a 14.4kW battery pack you would see a 20NM range at 4kts or a 11NM range at 5kts. Do not plan on regeneration as your boat will likely not produce much due to max cruising speed and limited propeller size and full keel.
