A masonry block drainage system comprising a sheet-like waterproofing strip for water-sealing the top of masonry blocks having vertically-extending cavities, at least one drainage fabric member, and at least one weep member for draining water from the drainage fabric member. to about 600 lbs. 15. A fishing line, comprising underwater gear, a surface buoy connected to said underwater gear via a buoy line, and at least a breakable link incorporated in said buoy line; said breakable link comprising, along a longitudinal axis thereof, two connecting portions for connection with said underwater gear and surface buoy, respectively, and a join portion joining said connecting portions together; one of said connecting portions being formed as an annulus extending continuously circumferentially for 360°; said annulus comprising a first portion joined to said join portion, and a second weakened portion having a rounded cross section of a cross-sectional dimension smaller than that of said first portion, whereby said annulus irrecoverably breaks at said weakened portion to disconnect said buoy from said underwater gear upon administration to said weakened portion of a load higher than a material failure load thereof; and said annulus further comprises an intermediate portion connecting said first and second portions, said intermediate portion having a rounded outer annular surface that gradually curves from the portion toward the second portion. 16. The fishing line of claim 17, wherein the cross-sectional diameter of said weakened portion is from about 50 to about 60% of the cross-sectional diameter of said first portion to ensure reliable break of said weakened portion. 17. The fishing line of claim 15, wherein said weakened portion extends circumferentially for from about 150° to about 210°. 18. The fishing line of claim 15, wherein said first and second portions extend eccentrically and symmetrically with respect to the longitudinal axis of said breakable link. 19. The fishing line of claim 15, wherein said connecting portions and join portion of said breakable link are integrally formed. 20. The fishing line of claim 15, wherein said connecting portions are separately formed and pivotably attached via said join portion so that said connecting portions are rotatable with respect to each other about the longitudinal axis of said breakable link while remaining inseparable along the longitudinal axis. 21. The fishing line of claim 15, wherein the material failure load of said weakened portion is from about 500 to about 600 lbs. 22. The fishing line of claim 15, wherein said breakable link is located between at least one of said buoy and said buoy line, and said underwater gear and said buoy line. 23. A breakable link, comprising, along a longitudinal axis thereof, two connecting portions for connection with a buoy and underwater gear, respectively, and a join portion joining said connecting portions together, one of said connecting portions being formed as a loop-shaped body extending continuously circumferentially for 360°; said body comprising a first portion having a rounded cross section and joined to said join portion, and a second weakened portion having a rounded cross section of a dimension smaller than that of said first portion, whereby said body irrecoverably breaks at said weakened portion to disconnect said buoy from said underwater gear upon administration to said weakened portion of a load higher than a material failure load thereof; and said body further comprises an intermediate portion connecting said first and second portions, said intermediate portion having a rounded outer annular surface that gradually curves from the first portion toward the second portion. 24. The break-away connector of claim 1, wherein, when said body irrecoverably breaks at the weakened portion, the first portion of said body remains joined to said join portion and, hence, to the other connecting portion. 25. The fishing line of claim 15, wherein, when said annulus irrecoverably breaks at the weakened portion, the first portion of said annulus remains joined to said join portion and, hence, to the other connecting portion. 26. The breakable link of claim 23, wherein, when said body irrecoverably b
