ABYC standards are sold commercially but Transport Canada publishes Construction Standards for Small Vessels (TP1332) on the web.<ref>Construction Standards for Small Vessels (TP1332), Transport Canada, http://www.tc.gc.ca/marinesafety/TP/TP1332/menu.htm</ref>
In particular see Lloyd’s Rules & Regulations for the Classification of Special Services Craft (Lloyd’s is more conservative than ABYC).
