Generic Size Chart
for
Fiorentino Para-Anchors
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.
Fiorentino size
recommendations are formulated
for Fiorentino para-anchors
and does not apply to other brands.
Fiorentino sizing data is collected from
real-life storm experiences and through
thousands of hours spent in sea trials.
Independent Government tests conducted on
Fiorentino parachute sea anchors also
contribute to the data collected.

 1. Small Vs Large Diameter.
Overnight layovers and drift fishermen typically require
larger parachutes. Smaller anchors are required for
heavy weather use.
2. Heaving To Makes A Difference.
Sailboats that heave to in most cases can use a
smaller para-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 para-anchor also determines the size needed.
Decide if your primary use for the para-anchor is comfort, safety,
or work. For example, the research vessel "Mako" is an 80-foot, 143-gross ton ship that effectively uses a 24' Fiorentino
para-anchor to stabilize
the boat. That means crew members sleep more comfortably. If safety is the primary concern, a 28- to 34-foot anchor is a better choice. If the Mako were
a commercial fishing boat, the better choice could be a 34' to 40' para-anchor to completely stabilize the boat for fishing. Fiorentino's Offshore Para-Anchors are built with exceptional durability and strength in mind to handle larger vessels. They can
be built to any length and configuration.
Return to Top
Kite fishermen on the East Coast of the United
States quite often use Fiorentino para-anchors
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.
