Sea Data Set TH52 English

Sailboats with a fin keel must have the transducer located at least 25 cm but not more than 75 cm in front of the keel. It should be placed no more than 10 cm off the centreline.

On sailboats with a pronounced “V” in the hull, such as full-keel yachts, it might be favourable to angle the transducer slightly so that it aims at the bow, rather than directly parallel to the centreline.

This will help balanced the passing waterflow measurement from one tack to another.

Avoid placing the transducer near the edge of sharp hull chines. Transverse waterflow in these areas can affect the accuracy of measurements.

If you have a questions about the location of the through-hull, contact your builder, yacht dealer, or other owners of similar boats for advice. Always remember to allow for accessibility from the inside of the yacht when determining the final location.
