The results are broken down by area tested. The sites had been initially selected based upon Washington State, Corps of Engineers and NOAA charts for differing soil conditions and were then surveyed on April 22 by diver Montgomery during a reconnaissance. Additional underwater site checks were conducted during testing to confirm bottom characteristics. Site 1. Off Point Monroe and entrance to Port Madison. Bottom consists of some scattered eel grass, kelp, and mostly sand. This was a good holding area for most anchors. There was some unevenness in the area which caused difficulty in maintaining scope at 5:1 when some anchors were pulled into deeper water. Table 1
*No drag at maximum applied strain. **Bent fluke. 1 Observers felt that the Luke moved more or less slowly and consistently at all times up to the time it broke free. In general they felt they were never confident the anchor had actually set. 2 The Bruce, Delta, MAX and Performance 35 set every time. 3 The Davis did not set in ten attempts. 4 These sets were on deep slope areas which presented more difficulty in setting. This was poor technique and not the fault of the anchors.
Table 2
1 Bent anchor shank and did not repeat veer test. (Previous straight line set at 4100.) Anchor did not break out. See Table 3. 2 No attempts were made on the Davis for the 90-degree veer as it had failed to set in ten consecutive attempts at straight pull. See Table 1, above. 3 No attempts at 90-degree veer conducted. The Gilcrest was having some difficulty maneuvering at this point. Table 3
1 Slow drag in all sets but resistance noted. 2 No 180-degree tests were done with Davis as the anchor had not set in ten consecutive attempts on straight pull test. See Table 1. 3 Pull into deeper water so scope changed dramatically. 4 Anchor initially set at 4100, then 90-degree at 4248 then 4001 at 180-degree. Shank bent during process so veer tests with this anchor not repeated. Underwater view of anchor shows it completely buried in sand initially, with about 4" of fluke out during veering tests. Site 2. Off Wing Point in an area of kelp (none detected from surface but indicated on chart)4 small rock and more rocky as it deepened. A poor holding area for all anchors. Rocks about fist size and hard glacial clay bottom. Anchors generally observed by divers as skipping over rocks without being able to penetrate clay. The larger surface anchors picked up a lot of kelp. |
