POSITIVE FEATURES
NEGATIVE FEATURES
Very Small
1
70%
  • Narrow profile and pointed flukes easily pentrate rocky bottoms and grasses and provides good holding
  • Due to having small holding surface, comes loose when it is forced in sand and mud
    It is too projecting and can not align itself to settle onto the pulley
    Under changing wind direction, chain can go around anchor's arm and make anchor come loose.
Convex
3,4
30%
  • Shape of anchor holds well in most bottom conditions
    Shape fits well in most bow rollers
  • Hard to set intially in the sea floor. Requires experience. When set it may come loose under high load forces by splitting the sea floor with its plow shape
    The articulated anchor shank lays to the side when at rest and does not add to the tip weight to help set the anchor. The anchor shank is found to lay on the bottom as anchor repositions
    Anchor shank may hit the jib furling reel
    When direction of pull changes, head of anchor does not turn same way as chain because of articulated shank. This causes anchor to come loose to one side, then must reset over long distance.
    Articulated shank has a pinch point that may hurt fingers when handling in rough conditions.
    Cast Anchors may break. Forged steels one are strong but expensive
1,8
45%

  • Shape of anchor holds well in most bottom conditions
  • Shape fits well in most bow rollers

  • Due to tip position in relation to anchor shank it can not hold easily
    Holding power is low
    When recovering anchor onboard, if anchor comes out backward it may not align itself to settle onto the bow roller. Lays to side on changes in direction
Flat
3,5
50%
  • Holds good in sand and mud.
    Style stores well below deck because of flat profile.
  • Due to its center of gravity is away from fluke tip, it is difficult to set in gravel and rough bottom
    Wide wings are difficult to catch in rock bottom
    If it is jerked, it does not hold well and slips
    The protruding top bar may hang up and make anchor hard to handle.
3,5
50%
  • If it can be set, holds well in sand and mud
    It is easily thrown from vessel by hand due to light weight.
  • Made of aluminium, wing tips are too light, hard to penetrate in the bottom
    When thrown, may not directly touch bottom because it is light. Chain touches bottom first, this makes it hard to set. Requires experience to use
    Requires different arm angles for each ground type. If you set at 32°, adjust for sand to mud bottom, can not easily hold, slips. If you throw 45° adjusted for mud to sand, it is difficult to recover. 45° angle is not advisible for rocks
    Due to its light weight , may require more scope than heavier anchors
1,9
30%
  • Lack of protruding top bar makes it easier to handle than other single plan type anchors. However, it does not have the advantage of the protruding rod to resist over turning
  • Flukes may not set in sea floor at the same time because of open space between flukes. Under load set fluke keeps its position but anchor shank pulls the other fluke out. It falls over that side by chain's pull causing anchor to slip because of these movements
    Even when totally set under heavy load may turn in the ground and come loose.
Concave

2,8
55%
  • Sets Quickly
    Does not come loose even under extra forces
    Reliable
  • Connection between arm and head is weak
    Chain will foul easily if it passes over side arms
    Inside of shank is not sharp therefore it can not mash grasses
    Hard to set in mud.
3,5
65%
  • Sets Quickly in sand with short scope
    Recovers easily
  • Does not hold on grass, side flukes handicaps anchor from setting and makes it slip
    Side flukes also blocks it from setting in rocks. Its tip is not pointed so it does not penetrate easily
    May require special handling device to align it to the boat's bow roller.
Dynamic Anchors


3,7
95%
  • Does not require experience to use.
  • Immediatly sets. Does not drag and is not destructive to sea floor
  • Holds well on reverse slope with its curved tip
  • Burries itself deeper and holds excellent under increasing wind condition.
  • Superior and certificate  holding power
  • Even under changing wind directions does not come loose
  • Automatically aligns itself to settle onto the bow roller
  • It fits to the boat's bow roller
  • Easily cleaned
  • The mixed complex geometry of this anchor and the fact that is hand-made and that can me made just in stainless steel, make the price very expansive
