Safety At Sea Studies - 1995 Anchor Study - Comparisons
|
AVERAGE HOLDING POWER
The results are slightly skewed in favor of the anchors tested with the higher horsepower boats. In a few tests the CQR, Delta and Performance 35 were not dragged because of limits on the horsepower of the boats setting those anchors. Nevertheless, the averages give a reasonable picture of relative holding power. Wing Point and Jefferson Head are not included as being generally foul ground. COMPARISON WITH OTHER ANCHOR TESTS A summary of the West Marine San Francisco mud tests of 1990 and the
1990 Biscayne Bay sand tests reflects the following.8
Comparison with Columbia River tests11 in sand bottom. Average Observations
Three other anchor tests are summarized in Appendix 2. They provide an interesting comparison. They confirm that the Bruce style generally does not perform as well as the CQR or Danforth types. The MAX anchor tests at Pensacola indicate that at least on those tests which were commissioned by Creative Marine, the MAX out-performed the FX 37, CQR 45 and Bruce 44 consistently. CALCULATED RODE TENSION IN WIND AND WAVES12 The following is Bob Smith's analysis of the force applied to sailboats of different sizes in wind and waves based on observations in the Columbia River. See "Anchors Selection and Use" 2d ed. (1983).
