I think not
If you were able to heat the water at the bow of a ship, would that not make the water less dense and cause the ship to settle deeper into the water, raising the water line, therefore creating more friction
The only way I know of reducing the drag or friction of a ships is to lift it out of the water, such as the hydrofoil, as the Russian Engineer Rostislav Evgenievich Alexeyev created.
Alexeyev was the first person that I know of to create high speed ships on the so-called low submerged underwater wings, They were manufactured from 1957 until today. the most popular ones being passenger ships Raketa, Volga, meteor, Kometa, and Burevestnik, with passenger capacity up to 150 persons and cruising speed up to 100 km/h (62 mph; 54 knots).
Not content with that. Alexeyev revolutionized the shipbuilding industry (though in secrecy) by inventing a craft that used ground effect, whereby a wing traveling close to the water is provided with a better lift-drag ratio - thereby enabling a combination of greater ship weight for less power and/or enhanced fuel economy.
This technology is from the sixties and I do not know and cannot understand why this method is not being used today.
The ekranoplan had wingspan of 37.6 m, length – 92 m, maximum take-off weight – 544 tons. cruising speed: 430 km/h (267 mph; 232 kn)
Until the Antonov An-225, it was the largest aircraft /ship in the world. It was designed to fly at an altitude of 5-10 meters and use the ground effect.

The Lun-class ekranoplan is a ground effect vehicle designed by Alexeyev and used by the Soviet and Russian navies from 1987 until sometime in the late 1990s. (Lun means Harrier from Russian)
It flew using the lift generated by the ground effect of its large wings when close to the surface of the water–about 4 meters (13 ft) or less. Although they might look similar and have related technical characteristics, ekranoplans are not, aircraft, seaplanes, hovercraft nor hydrofoils, ground effect is a separate technology altogether. The International Maritime Organization classifies these vehicles as maritime ships.
