HARD BOTTOM AREAS
| Location: | ||||||||||||
| There are 3 areas in the Martín García Channel where hard material is present in the river-bed: | ||||||||||||
|
| Effects of the speed on the "squat" | ||
 |
The design speed for Panamax type vessels sailing downstream at 32 feet is 7 knots and saling upstream in ballast 10 knots. The existence of hard bottom areas prevents the developement of speeds higher than the design speed in any of this areas, specially between curves km 62.3 and km 67.8.The squat effect dramatically increases the draught of the vessel at excess velocity. Most Panamax trim by the bow as consequence of the squat effect. |
