6. Check that the valves on all through hull fittings are closed; namely, the
sink drain and marine toilet intake and outlet, if one is installed. Check that
all hose clamps are tight.
7. If the boat is being launched by a hoist with slings, it should be positioned
under the hoist. One sling should be placed forward of the keel, and the
other aft. It is good practice to tie the slings together to avoid the-
possibility of these slipping apart. If wire in the slings is likely to damage the
vinyl rub rail or the hull, these areas should be protected with rags or any
suitable materials.
8. Lift the boat well clear of the cradle or trailer. If it appears that the slings
are badly placed so that the boat tilts either fore or aft to any marked
degree, it should be lowered and the slings repositioned.
9. If necessary, apply anti-fouling paint to the areas covered by the cradle
pads. It is not necessary for these small newly painted areas to be dry
before launching.
10. Lower into water, release slings and tie up alongside.
11. Open through hull valves and check for leaks.
12. Proceed with rigging.
TRAILER LAUNCH
The procedure to launch from a trailer is as follows:
1. Ascertain the length of the ramp that you intend to use and the maximum
depth of water at its lowest point. You will require about 3'6" of water to
launch your Tanzer 22 keel/centerboard model; this will vary with the
height of the trailer bed. If it appears that this depth of water will not be
available, or that the wheels of the trailer will run off the end of the ramp
before the boat floats, do not attempt launching.
2. If the ramp appears suitable, remove mast and mast racks.
3. Follow steps 2 through 6 above.
4. Back the loaded trailer into the water as far as is possible without
immersing any part of the towing vehicle.
5. Place chocks under trailer wheels and install dolly wheel. Unhitch trailer
and drive vehicle up ramp a few feet. Secure a strong rope to trailer and
take one or two turns around the trailer ball hitch and the vehicle.
6. Remove chocks and allow trailer to proceed down the ramp by surging
rope around hitch until the boat is afloat. If your trailer is equipped with a
launching tongue extension, this should be used; in which case the trailer
may be backed into the water with the towing vehicle until the boat is
afloat.
7. When afloat, the boat may be controlled either with the lines from the
bow and stern or by the motor. In the latter case a person should be in the
cockpit prior to launching.
8. Open through hull valves and check for leaks.
