SOMETIMES, the circle format of the comic “Family Circus” is likened to a porthole, through which the reader can gain a window into the cartoonist’s world.

Well, come this winter, in real life and time, you can access a dozen such portholes. Twelve top-flight cartoonists are taking to the Caribbean seas in January, and inviting you to come along.

Yes, if you love opening up a paper or digital page to an ocean of comic strips or editorial cartoons, then you’re perhaps a prime candidate to climb aboard, well, we’ll call it the Good Strip Lollipop.

And you can chart a course or three, as well; the featured cartoonists will offer art classes and signings and sketch sessions.

“We’ll have four Pulitzer Prize winners and eight Reuben Award winners,” Steve McGarry (“Biographic,” The Minions), president of the event-organizing National Cartoonists Society Foundation, tells The Post’s Comic Riffs.

The “Celebrity Cartoonists Caribbean Cruise 2016” will feature a porthole not only into the mind of “Family Circus” cartoonist Jeff Keane (aka “Jeffy”), but also some time with the “Zits”/”Baby Blues” triumvirate of Jerry Scott, Jim Borgman and Rick Kirkman; “For Better or for Worse” creator Lynn Johnston; “Mother Goose and Grimm” creator Mike Peters; incoming NCS president Bill Morrison (“The Simpsons,” “Futurama”); cartoonist/greeting-card artist Rick Stromoski; and MAD caricaturist Tom Richmond. Besides Borgman and Peters, the Pulitzer-winning political cartoonists will include Mike Luckovich and Michael Ramirez.

Proceeds from the cruise — which departs Orlando, Fla., on Jan. 17 and returns seven days later, with stops in Haiti, Jamaica, Grand Cayman and Cozumel, Mexico — will benefit the NCS Foundation.
