When will the boat be delivered?
In meanwhile enjoy Brittany. I am sure you are going to love living in Treguier, it is a lovely town. Take the opportunity to cruise around, that's a great place Brittany: Saint-Malo, Paimpol, Lannion, Pornic and my three favorite, Mont Saint Michele, Quimper and Locronan. Quimper and Locronan are central in the Celtic tradition.
Britons love beer and they have incredibly good traditional beer. You will not find it in restaurants. Try this place in Locronan:

They have an incredible collection of traditional beers (1L bottles), around 100 different brands, and I am not talking about factory made beer. If you like beer you are going to love it.
Regarding travel lifts, they have them on the Atlantic coast too but those big tides make sometimes a crane more useful.
