In order to avoid Velocity Time Dilation due to near Speed of Light travel, Gravitational Time Dilation may be used to compensate for the temporal changes. A gravitational generator may be placed at the front of a ship. As the ship approaches the Speed of Light, the gravitational generator will need to increase its gravitational output.
Increased gravity may be uncomfortable for the passengers and crew. So to create an opposing force, the ship's rate of acceleration will need to increase as well.
