A laser underwater would be completely impractical
the light would be scattered to buggery and absorbed in a short distance,
light doesn't travel very well through water,

An energy weapon such as a photon torpedo or plasma pulse could be effective, it would have to work on the same principles as supercavitating torpedo's such as the Russian VA-111 Shkval to travel at high speed through the water without contacting it.

Assuming ridiculous amounts of energy, magnetic shielding may be possible by projecting a strong magnetic field around the boat you could in theory deflect or detonate incoming weapons away from the hull, however the field itself would give away your location
