I've been to some of those areas but with less than 3' draft you will have many more options than we did, including leaving the channel when the tow and you are headed for the same corner.
The only tip I can think of is to not fear the crossing just wait for the best weather, then it is a hop across the pond but with such little draft you might be able to completely avoid any significant hop. After learning the hard way we waited a week for nice weather.
Have faith that the oceans are going to rise and flood the world, that plague and pestilence brought on by Climate Change is going to punish us for not believing. Please do as they say it is our only hope. :P
