Seriously, just take it SLOWLY. Assuming your concerns are reversing - Start somewhere where you can do no harm, a deserted car park for instance, and give it a go. With a 4m boat and trailer, if it starts going pear shaped you can always un-hitch it and start again.
You will need to check out which technique you are most comfortable with, screwing your neck around and twirling the wheel whilst watching the boat, or sitting square and watching the boat in the mirrors - I tend to use either, depending on the situation.
If you are talking about practicing before you collect the boat why not try hiring a small-ish trailer and try reversing with that. Not much help for you, but strangely I find reversing with a bigger trailer to be a bit easier than a shorter one, but all it takes is practice
