Ok, so you are an immigrant and you've just hiked across Oorope and lo and behold you get to Calaise and this nice French chap says here mon amee here iz my boat you can have eet for free.
So you have a boat. Ok you are an immigrant with the means to get across the sea to good ole Blighty where the streets are pathed with gold.
Does that mean it easy to sneak into Britain?
Naw because you have to pilot that boat across the busiest sea lanes in the world. In unforgiving tides and mostly **** weather conditions.
SO NAW (even with a boat) IT'S NOT ****ING EASY TO SNEAK INTO BRITAIN.
