Properly executed crimps, using the correct crimping tool, provide strain relief by design. An insulated crimp of good quality for the marine environment will consist of three pieces and two crimps will be made, one for strain relief clamping down on the jacket, and one on the bare stripped wire.
As a point of interest I have cycled both double crimps and heat shrink crimps over 100 times a full 180 degrees, side to side, with UL 1426 wire, and seen no detrimental effects..
