Have a really big yacht you've been meaning to take out on a spin in the next couple of weeks? Might have to think again.

The large lock at the Hiram M. Chittenden Locks will close to all marine traffic from 9 a.m., Nov. 6 to 5 p.m., Nov. 20 for their annual maintenence.

To serve most peoples' purposes -- barring a Death Star-sized yacht, of course -- the small lock will still be available to vessels less than 115 in length and 26 feet in width throughout the maintenence period.

The BNSF Railway will also make structural upgrades to the Ballard railroad bridge, which crosses the Ship Canal west of the Locks. This means that high mast vessels will not be able to pass the bridge during its maintentence. The railway closure will be from 7 a.m., Nov. 7 to 5 p.m., Nov. 18.
