The goal all along has been for the ship to take much-needed medical supplies and personnel into the Pacific Islands.
The strong and versatile vessel is uniquely designed to carry both people and cargo to remote island communities.
On its last visit to Whanganui in November 2019, a container fitted out for dental work was craned aboard.
The container was donated by Emmett Civil Construction, inspired by Whanganui dentist Hadleigh Reid, and fitted out by engineer Jaime Barrett, using donations from Whanganui businesses.
After its Whanganui visit the Koha will be in Wellington from April 23 to May 9 for fundraising and more tours.
YWAM hopes to sail it into the Pacific in July, fully funded and with a volunteer crew.
The ship is open for free tours on Wednesday, April 14, 1-5pm; Friday, April 16, 1-5pm;
Saturday, April 17, 10am-6pm; and Sunday, April 18, 1-5pm.
