The Great Strugglers Boat Trip 2007
Oh yes!
Here follows advertisement crap of a nice route...
"One week from Strand Horst
Strand Horst - Amsterdam - Utrecht - Elburg round trip
Friesland - North Holland - Utrecht
Cruise the River Vecht and delight in the country houses lining the canal, formerly the weekend residences of wealthy business owners. Moor at Weesp and take the 10-minute train journey to the cosmopolitan city of Amsterdam. Tour the canals, visit the many tourist attractions, perhaps visit a diamond polishing factory. Cruise to Utrecht and return via Spakenburg.
180km 4 locks 33hr round trip cruising time"
I would like to point out that this route is using a cruiser rather than a narrowboat, so would give a new fun handling experience into the equation - well we do have to do something to make up for the lack of locks ;)
Also, given that Matt has indicated that he might bring his girlfriend along - the boat in question has a double cabin at the front.
