Hartge Insurance Associates Ltd. is celebrating its 25th anniversary insuring boats.

“Most insurance companies don’t want to write the coverage we concentrate on, including what I call difficult vessel risks,” Totch Hartge said in a statement. “Considering the age, construction, navigation areas and historic vessels, the owners still need coverage, like the 1886 skipjack Rebecca Ruark.”

Hartge is a descendant of 150 years of boating business in Galesville, Md., and on Maryland’s Eastern Shore, where members of his family have a tradition in the maritime industry.

He first entered the insurance business in 1972 in Annapolis after he was involved in a trans-Atlantic race and other sailing events around the world.
