If you are going to YC, not BC, then head left when exiting Kouzzina. Head towards the S/D, but when you leave BW property, at the bridge, go right..this will drop you at the YC...takes about 10 mins tops, depending on your walking speed.
You could take the boat to DHS.....the YC dock is the first stop after leaving BW. But, if the boat is just pulling away as you get there, it could be another 20 mins before the next one comes.
