STEP 6(a): ALIGNING THE TANKS
Side Alignment
1.
Align the tanks next to each other, five on each side, spacing them so the lifting rings are
68.25”
apart. You may
want to use the full
-
length hull support bracket as a straight
-
edge to align the tanks. The hull support bracket is
used in a later step.
2.
Align tanks opposite each other using the rules for minimum beam of lift or beam of boat. See Step 6(b) for proper
alignment.
Verify the tanks are separated enough to accommodate the cross channel in STEP 6(c).

The
minimum beam of the lift is calculated by adding 34IN. to the beam of the boat. If the lift uses AUX
tanks, the minimum beam of the lift is determined by the width of the AUX tank. Refer to Table 1.
When sizing the slip this way, it will leave a minimum of a 4IN. gap for each of the lifts. Near this width, the
walkway could catch on the edge of the dock while raising or lowering. Dock fenders are recommended to pre-
vent this. See Chart 1 for minimum lift widths.
