Stern anchor suggestions
Some facts and figures about some anchors:
Holding power, first in Sand then in Gravel.
CQR Lewmar(16,5kg)- 900kg - 650kg best numbers but "with a big snag: when dragged it finishes up on its back...so it did not rebed".
Brake MPI(20kg, but same size)-1000kg-400kg
"it doesn''t have the consistency of the spade or CQR" (can suddenly break out).
Delta Lewmar(15,5kg) - 400kg - 350kg
Spade (15kg)- 900kg - 300kg "..it is almost impossible to break out. It drags very slowly while maintaining excellent holding power".
Topguard MPI(16kg) - 350kg - 150kg
Claw Lewar(14kg)(type Bruce)- 150kg- 100kg
FHD Plastimo(15kg)(type Bruce)-220kg-150kg
Spade (6,5kg) - 650kg - 70kg "in gravel the spade does not bed in."
Fortress(6,5kg) - 370 - 25
