The replica vessel is in Douglas but has faced logistical issues for tours
Revised hours have been arranged for the public to go onboard the replica of the Spanish Galeón Andalucia tall ship.
Low tides have meant that safe access has been restricted to the vessel which is currently moored in Douglas.
The ship will now be open from 4.30 until 8pm tonight.
However, because of the high demand and the number of rescheduled slots, organisers are advising people not to buy new tickets.
Those who can no longer make their booking are entitled to a refund.
It will be in Douglas until Monday.
