Interest in a Mac cruise that combines Alaskan glaciers with iMacs drew a record response from Macs fans.
When Neil Bauman, captain and chief executive of Geek Cruises, announced a week long MacMania cruise he claims he was "deluged" with responses from Mac fans, putting past cruises in the shade.
Bauman said: "They're geeks and they're absolutely full of enthusiasm. Any other Geek-cruise theme pales in comparison.
"The best email of all was from one individual who 'demanded' to send in a cheque."
The cruise that sets sail in May 2002 will have speakers and conferences dedicated to Mac OS X developers and Mac users. The cruise will journey across Alaska's Inside Passage, in the state's South East.
Bauman has organized five Geek Cruises to date, including XML Excursion, Database Discovery and Perl Whirl, with eight more planned before MacMania's intrepid voyages.
MacMania could revive Bauman's flagging business. Past tech cruises have drawn a low attendance of between 50 and 175 passengers, the Mac themed cruise could attract about 400 sea-goers.
Cruisers will have to pay at least $1,100 for room and board, with a conference fee of $600 to $1,250.
