the slack out of each tuck and check the size of the eye. (If a thimble is to be used, insert it at this point.) Follow the “over one strand, under the next” procedure until you complete at least three tucks for natural fiber line or four tucks for synthetic line. (NOTE: The splice can be smoothed by rolling it on deck under your foot.) Upon completion of the splice, the excess length of each strand must be cut off. When natural fiber line is used for the splice, the strands can simply be cut off near the line. With synthetic line, a short length of each strand should be left intact. The ends of the threads of each strand are then melted together over an open flame to prevent the strands from frazzling. When you melt the ends of the strands, don’t allow any of the melted synthetic line to drip on you, your clothing, another person, or anything that might present a  fire  hazard.  Also,  observe  all  safety  precautions pertaining to the use of open flames aboard your ship or station. Short Splice A short splice is used where two lines are to be permanently joined, provided a slight enlargement of the diameter is not important. When properly made, the short splice is much stronger than any knot. After  unlaying  and  whipping  the  strands  as described for the eye splice, seize each line where the unlaying stops. Now butt the two lines together so that they are interlaced, and follow the steps shown in figure 7-23. With  large  lines,  you  must  put  on  a  temporary seizing where they join to keep them from suddenly coming apart. It’s better to do that with small lines, too, until you get the hang of holding them together while you tuck. Once your seizing is on, tuck over and under the same way you finish off an eye splice. Three tucks (natural fiber) or four tucks (synthetic fiber) on each side of the seizing are ample. Remove the seizing, cut off  the  ends  of  the  strands,  and  melt  them  (if appropriate) as previously described. SECURING FOR SEA You are required to learn these knots, bends, and hitches  so  that  you  can  use  them  when  and  where necessary. Rest assured that a person who goes to sea will find frequent use for them in securing equipment to prevent damage from rough waters. How the equipment is  secured  depends  on  the  gear  and  the  places  of stowage. By observing the few tips that follow and by using a little common sense, you should be able to do a good job of securing your equipment for sea. Use line strong enough to hold the gear. Make certain the line is in good condition. Make fast the belay objects from at least two points that, preferably, are near the object. Lash tightly all objects against something solid (such as the bulkhead). 7-19 Student Notes: Figure 7-23.—Steps for making a short splice.
