The St. Lucie Lock is the first lock out of five you must go through when you cross Lake Okeechobee to get to Florida's western side. The water rises about 8 feet in this lock. To make the water rise the lock master just cracks the lock gates a little bit. The water comes in. Your boat rises. You drive out. Seems pretty simple, huh? The lines are even provided for you. All you have to do is keep pulling in and tightening them up as your boat rises. Well it would be that easy if the beast weighed less than 125,000 pounds! I pulled the stern line as hard as I could and still couldn't keep Valkyrie against the wall with the force of the water and the wind. Seriously my arms felt like I had just spent an hour with a personal trainer at the gym. Finally Don took pity on me and came to the rear and used our thrusters to move the stern in closer so I could tighten up on the line. Now to sign up for a gym membership!!!
