Two friends who study yacht design are missing and authorities are looking for traces of them.

Zachary Wells, 21, and Prescott Wright, 23, were last seen drinking a beer with some friend at Wells' home in Kennebunkport, Maine. Both Wells and Wright attend The Landing School where they study boat building and yacht design, according to ABC.

When the two men failed to attend class on Thursday and Friday, the school notified police.

Police searched the home and found no disturbance. They then searched by air, in the water and in wooded areas.

Sanford said police continue to investigate with the help of the Coast Guard and Marine Patrol checking the coastline, looking for the missing men.

"We currently have not hard facts to support the men going into the water at this time," police chief Craig Sanford told WMTW. "Because of the residence being in close proximity to the water, we felt it prudent to ask for the search of that area."

It seems that both men left the home together but it is not known when or how. Only one of them owns a car and it remains in the driveway.

Police spent all weekend looking for a trace of the men. As of Monday, their clothing was found on an island near Kennebunkport.

Police are continuing to do flyovers of the area at low tide where the clothing was found.

"The members of our agency have the families in our thoughts," Sanford told WCVB. "We will continue our investigation until we have some concrete findings."

Anyone with information is asked to call the Kennebunkport Police Department at 207-967-2454.
