Splicing is an art, and the final appearance is your reward. Done correctly, the short splice is aesthetically pleasing and strong.
Although stronger than the long splice, the short splice increases the line’s diameter, making it difficult, if not impossible, to pass through a block.
To splice 3/8-inch laid rope, unlay about 8 inches at the end of each line to be joined, for a total of six strands using three-ply rope. Heat-melt the end of each strand.
A. Intertwine the strands as shown, with strand 6 between strands 1 and 3 and strand 2 between strands 4 and 5. Pull the ends to tighten the rope.
B. Secure the center with a twine sack knot to hold the ropes while you complete the tucks.
C. Make the first tuck by passing strand 1 over strand 4 and under strand 5. Rotate the splice a bit, and make the second tuck by passing strand 2 over strand 5 and under strand 6.
D. Make the third and last tuck by passing strand 3 over strand 6 and under strand 4. This completes one set of tucks.
E. Make two more sets of the three tucks, going over and under as described above. Make sure that all the strands are pulled and twisted with the lay after each set of tucks to snug the strands in place. This makes the final splice neat and firm.
F. Next, turn the splice end-for-end, making three sets of tucks on the other end as well.
Remove the twine sack knot, place the entire splice on the deck, and roll it back and forth with your foot to smooth the splice and make it uniform. Heat-cut the protruding ends of the strands and hide them by dimpling using a heat melt
