5.1.2 (continued)
After the ballast has been installed it is recommended that the
hull be very
carefully replaced in the cradle so that all of the weight of the boat rests on the
keel, with the saddles of the cradle used only to keep the boat from falling. Be
sure you have adequate carpeting covering the cradle saddles so it does not mark
the hull. The whole boat should then be leveled very carefully. This is done by
fastening clear plastic hoses to the hull, one on the port side taped to the hull
,above the waterline and running under the boat to the starboard side -- again
taped to the hull above the waterline. The second tube should be fastened at the
bow above the waterline and run aft to the stern and taped to the hull above the
waterline. These hoses should be filled with a vegetable dye colored water. Then
level the boat so that the water level is exactly the same dimension fore and aft
and port and starboard above the waterline.
After the hull is perfectly level you can proceed with your next step.
5.1.3 Temporary Cover Over Work Area
It is recommended that a temporary cover be built over the area in which you will
be working. The roof should be strong enough to protect your work area from snow
and rain and if you are working in a colder climate it is suggested that
inexpensive plastic sheeting be used to construct a windbreak all the way around
the structure. Be sure that the roof is high enough so you can stand up on deck.
Since you will be doing fiberglass work it is important that the average
temperature to held reasonably constant so that your fiberglass were will turn out
well. Extremes of humidity or temperature will produce poor fiberglass work which
will have =o be done ever. Be sure you have good ventilation while you are doing
fiberglass work to protect your health.
Having a temporary enclosure for your work station will make it more pleasant and
enjoyable to build your Sailcrafter Yacht.
5.1.4 Importance of Leveling
The importance of checking all your work with an accurate carpenter's levelcannot be
over emphasised. Since your boat is level, checking each of the parts you install
with a level will your final product square and true with respect to the waterline
of the boat. If you have purchased your
