The Love Boat cast members enjoyed a mini-reunion on Tuesday in New York City.
The crew who will be 'making another run,' on a cruise in November got together for a special occasion - the off-Broadway debut of Lady Patriot, written by original cast member Ted Lange.
Lange, 77, who starred as Isaac the bartender from 1977-1987, wrote and directed the play about the hunt for a spy at the Confederate White House during the US Civil war.
Jill Whelan, 58, who played Vicki Stubing, the daughter of the late Gavin MacLeod's Captain Stubing, stars in the show along with Fred Grandy, 77, who was ship's purser, Burl "Gopher" Smith.
In the audience was Bernie Koppel, 92, who starred as Dr. Adam Bricker.
Whelan shared a photo of the foursome with other members of the cast in her Instagram Stories writing, 'Bernie Koppel flew to support his loveboat cast!' tagging Lady Patriot cast members Josie DiVincenzo, Count Stovall, Derek Emerson Powell, Gordon Goodman and Chrystee Pharris.

Lady Patriot takes place at a time when secrets from the inner sanctum of the Confederacy are being leaked to the Union and they are looking for the person responsible.
The plot focuses on three women of the time, Varina Davis, a the wife of Confederate president Jefferson Davis, Union sympathizer Elizabeth Van Lew and the formerly enslaved Mary Bowser.
Lange said he was inspired to write the play after reading a book about Van Lew.
In a release explaining his inspiration, he wrote, 'I happened upon the contribution of Black slave, Mary Bowser, as a Union spy, [and] I added into the mix the plight of the confederate first lady, Varina Davis. I soon realized I had a story about the patriotism of three different schools of thought.'
On working with and directing his former co-stars, Lange said, 'I delight in working with my Love Boat cast mates, Jill and Fred. We have artistic chemistry and it is fun to see our love of theatre blossom on stage.'
'It's really special because I'm working with them as an adult now rather than as a kid,' Whelan told People in May.
'We enjoy each other's company and we enjoy each other's intellect -- whether we have it or we don't -- but we all love each other's sense of humor and we know each other so well. When we work together, there is a shorthand that is super satisfying.'
