Good Opsec is required but no matter how good your Opsec is, failure to plan is planning to fail. Your posts continue to be generic responses and provide no useful information for any of the forum members. Here is a simple example that does not require any disclosure of Opsec information. Channel crossing will require knowing the weather located in your chosen departure point. What will the tides be -- high tide or low tide, at any given departure time. The person bugging out will need to know the weight limit / carrying capacity of the of the boat being used. Will the boat be motorized or sail driven? If motor driven, how much fuel will be required? Should the motor fail, will you be able to continue the journey? These are just a few sample question needed to prepare for a channel crossing. I am sure many others will be interested in how you plan (?) to deal with these issues, other than not a problem.
