"Hitting The High Seas" was the first episode of The Monkees to leave out the laugh track.
Screen Gems' original synopsis for this episode lists the Queen Anne as the Queen Elizabeth. It also reveals an alternate ending to the romp, showing The Monkees bowling the pirates over with cannonballs.
"Daydream Believer" is featured here (its fourth and final time on the series) in a mono mix that can be heard on the A-side of the single, as well as on the ultra-rare mono version of The Monkees fifth LP, The Birds, The Bees & The Monkees. In the three other episodes ("Art For Monkees Sake," "Monkees Marooned" and "A Coffin Too Frequent") on which the song is featured, its mix has neither echoed lead vocals nor string parts in the instrumental break.
"Daydream Believer" became The Monkees' third and final #1 hit (for five weeks).
On the first day of shooting this episode, Mike Nesmith actually contracted a real case of seasickness; hence his prolonged absence.
The voice of Horace the parrot is played by Micky Dolenz.
In the galley, you can spot Micky Dolenz and Peter Tork performing an impromptu acoustic rendition of the latter's newly composed "Tear The Top Off My Head." Peter produced a version of the song in the studio three months after this episode aired, although it was shelved until the 1991 release of the four-CD Monkees Box Set, Listen To The Band.
Micky, in his guise as Captain Horatio Hornblower, wears the exact Commodore's outfit worn by Mike in "Everywhere A Sheik, Sheik."
The Monkees were so taken with the old sailing ship they used for the filming of "Hitting The High Seas" that they actually made plans to buy it. Unfortunately, the ship sank only days before the final details could be drawn up and completed.
The front cover of The Birds, The Bees & The Monkees album uses cutouts of Mike, Davy, Micky and Peter from color stills of "Hitting The High Seas."
Writer Jack Winter and director JIm Frawley collabrorated on the very next episode, "The Monkees In Texas"--their third and final collaboration on the show.
"Hitting The High Seas" tied "Some Like It Lukewarm" for the highest-rated episode of The Monkees' second season. Both had 11,140,000 viewers.
When "Hitting The High Seas" was first rerun on CBS Saturday Afternoon, "Oh My My" replaced "Daydream Believer" on the soundtrack.
Davy's line, "Peter's so tough, 'e loves the sight of blood, 'e pours ketchup on everythin' 'e eats; even Cornflakes!" refers to the famous product of the show's main sponsor, Kellogg.
The short edit of Goffin & King's "Star Collector," heard in the beginning of this episode, makes its first appearance on the show in a mono mix (with Moog synthesizer effects from the mono version of the Pisces, Aquarius, Capricorn & Jones, Ltd. album) that is used again in "The Monkees Watch Their Feet."
