Generic Size Chart & Guidelines
Developed by Fiorentino


When sizing a Fiorentino Anchor always consider vessel design, length, weight, beam, draft your boat's windage and intended use. Examples are provided below. For more specific details on para-anchor sizing and required accessories, please fill out our boat spec form.

Cruising Weight Boat Length *Diam. (U.S.) Metric
10,000 lbs. 30' 6' 1.83 m.
20,000 lbs. 35' 9' 2.74 m.
30,000 lbs. 45' 12' 3.66 m.
40,000 lbs. 50' 16' 4.88 m.
46,000 lbs. 60' 18' 5.49 m.
50,000 lbs. 65' 21' 6.40 m.
*over 50,000 lbs. over 65' 24' 7.32 m.
*over 50,000 lbs. over 65' 28' 8.53 m.
*over 50,000 lbs. over 65' 34' 10.36 m.
*over 50,000 lbs. over 65' 40' 12.19 m.


1. Small Vs Large Diameter

Overnight layovers and drift fishermen typically require larger parachutes. Smaller anchors are required for heavy weather use. Kite fishermen on the East Coast of the United States often use the Fiorentino anchor two times larger than what's required for storm safety. Fishermen really like to slow down their boats so they can stay on their fishing grounds longer. Related Links: Sizing Wind Horse with a Smaller Anchor

2. Heaving To Makes A Difference
Sailboats that heave to in most cases can use a smaller Fiorentino anchor because the boat's hull creates more resistance when it drags through the water. Another option is to deploy one straight from the bow. Heaving to allows more flexibility on Fiorentino's size chart. For example, a 36' sailboat with a full keel and cruising weight of 20,000 lbs. can hove to nicely with a 9' para-anchor. A 12' para-anchor is needed when deploying the para-anchor straight from the bow.

3. Windage Also Matters
Owners of multihull sailboats and power vessels with super structures or towers should consider going one size up.

4. Primary Use
How you plan to use your Fiorentino anchor also determines the size needed. Decide if your primary use for the anchor is comfort, safety, or work. For example, the California Department of fish and game's research vessel, "Mako" is an 80-foot, 143-gross ton ship that effectively uses a 24' Fiorentino anchor to stabilize the boat. That means crew members sleep more comfortably. If safety is the primary concern, a 28-foot anchor is a better choice. If the Mako were a commercial fishing boat, the better choice could be a 34' to 40' Fiorentino anchor to completely stabilize the boat for fishing. Fiorentino's Offshore Anchors are built with exceptional durability and strength in mind to handle larger vessels. They can be built to any length and configuration.
