CLASSIFICATIONS

Trailers are separated into four classes based on gross vehicle weight

(GVW). Gross vehicle weight equals the trailer weight plus the maximum

load it may carry at 60 MPH.

• Class One GVW under 907 kg (2000 lb)

• Class Two GVW over 907 kg (2000 lb) under 1588 kg (3500 lb)

• Class Three GVW over 1588 kg (3500 lb) under 2268 kg (5000 lb)

• Class Four GVW over 2268 kg (5000 lb)

HITCH

Hitches are divided into classes that specify the gross trailer weight (GTW)

and maximum tongue weight for each class. Always use a hitch with the

same class number as the trailer, or greater.

Most boat trailers connect to a ball hitch that is bolted or welded to the

towing vehicle. Special heavy-duty equalizing hitches are necessary for

trailer tongue weights of 159 kg (350 lb) or greater.
