Why two boats moving in parallel directions close to each other get attracted?

Assertion : When two boats sails parallel in the same direction and close to each other, they are pulled towards each other. Reason : The viscous drag on a spherical body moving with speed v is proportional to v .

Why two rowing boats moving parallel to each other come closer (attract) to each other ?

If two rowed boats happen to sail parallel and close to each other, they experience a force which pulls them towards each other. Give reasons for it.

Statement-1 Two parallel wire carrying current in same direction attract each other, whereas two proton beams moving parallel to each other repel each other Statement-2 Wire carrying current is electrically neutral, therefore it is experiencing only magnetic attraction while the electric force of repulsionn between protons is more than the magnetic attraction
