Here’s what one of our customer is saying about XYZ boat anchor

Tuesday, May 18th, 2010

Hi Drago,

I am still using your excellent XYZ anchor. My first seasons experience with your anchor was used in the North Channel, Georgian Bay, Lake St. Clair, and various inland lakes. The XYZ set and held in every instance and I was able to retrieve it without any additional difficulties. Due to health reasons I couldn’t get out on the water last summer, but I did recommend your anchor to some Gemini Catamaran cruisers I met in Annapolis last fall. They were commenting on the Bruce and Delta anchors and some of their shortcomings and I suggested they look-up the XYZ as I’d had nothing but success with it. I hope they followed through and bought one or more. I would be happy to give a recommendation to anyone else. Nothing is as comforting as knowing you’re not dragging anchor and you can have a good nights sleep. With safety a paramount concern a good anchor is virtually priceless.

I hope the economy turns around soon and I hope that you might find comfort knowing you have a good product.

How we analyze and test XYZ Boat Anchor

Tuesday, May 18th, 2010

As essential front line SAFETY DEVICES, boat anchors should be tested to their limits under a variety of conditions. Users need absolute confidence in the anchors they are using life and vessel are dependant on them. Our anchoring tests, influenced by the auto industry break/crash protocol, reflect anchoring in real conditions: normal and extreme. They have been conducted on various anchoring sea bottoms: soft/hard sand, mud and clay with some weeds, and small rocks.
As our designs evolve, each model is analyzed with state of the art CAD/software to maximize performance under the most demanding conditions. Field testing confirms the CAD simulation predictions.

XYZ Extreme Anchor meets or exceeds the PASS Criteria of the four sets of test conditions as shown below.

BOAT ANCHOR TEST #1
Anchor Setting and Breakout Test
Test was started with an anchor on the bottom at 5:1 scope. From idle speed, power is slowly increased to high RPM to enable anchor to set. RPM was increased to 2000 and held continuously (force 9,000lbs) for 30 seconds. Once the anchor was set, the same exercise was done at 90˚, 135˚ and 170˚ direction.

To pass the Test #1, the boat anchor must HOLD and not drag or break out from any direction. During the tests, the anchor must rotate below the bottom surface, without pulling out and HOLD at the high RPM – force 9,000lbs/4 ton. After rotation is completed, the boat must be stopped in less then 3’/1M.

BOAT ANCHOR TEST #2
Anchor Breakout Test – Sudden Impact Test
When the anchor is set, the boat will relocate above the anchor. With a slack rode (length for 5:1 and 3:1 scope), the boat is given full throttle (maximum RPM) so that the anchor would be hit by the sudden and enormous force of the boat’s mass/speed, simulating hurricane force wind conditions. The sudden impact test is done at 0˚ (the previously set direction), and at 90˚, 135˚ and 170˚ to the original set.

To pass the Test #2, the anchor must HOLD and not drag or break out from 0˚ up to 135˚. The anchor must rotate quickly below the bottom surface, without pulling out. The vessel must be stopped in less then 3’/1M. (30,000lbs/400HP/12mph). Under maximum RPM and sudden impact force, on 0˚ orientation, the rode should break (standard recommended nylon sized for the anchor weight – for 25 lbs/12kg anchor – 5/8”/16mm nylon rope breaking strength 11,000lbs). The anchor should not be damaged in any way.

BOAT ANCHOR TEST #3
Panic Test Anchor Setting Under Motion Boat Speed
3 mph @ 5:1 and 3:1 Scope
This test simulates a panic situation where the vessel is in motion due to high wind. At 3 MPH anchor is dropped in the sand bottom at 5:1 and 3:1 scope.

To pass test #3, the anchor must set and HOLD a 5:1 scope. Once set, it must pass tests #1, 2 & 3.

BOAT ANCHOR TEST #4
360˚ Maximum Load Test5:1 and 3:1 Scope.
Once the anchor is set, vessel makes full 360˚ circle around the anchor, under constant load (maximum RPM), at 5:1, 3:1 and 2:1
scope.
To pass test #4, the anchor must HOLD at lease 5:1 and 3:1 scope.
