APIA, SAMOA » During a picturesque drive along Upolu's northeastern coast last week, Hokule‘a and Hikianalia crews were hard at work cracking up one another — mostly with bad impressions of crew members — as their caravan neared the village of Faleapuna.They were giddy and more than a bit anxious to get back on the water. Their journey — the Samoa leg of the canoes' worldwide voyage — started just a few days prior with a swift overnight sail from Pago Pago to Apia Harbor.Despite all the laughs, apprentice navigator Celeste Ha'o was all nerves. For the 27-year-old Hilo native, this drive to her family's village marked the end of a voyage that began 10 years ago.It was not the ending she expected and certainly not the one she hoped for. But she believes that everything happens for a reason. She chuckled at a botched impression that was supposed to resemble a New Zealand accent but instead came off sounding Rus­sian. The car snaked onward alongside glistening turquoise waters.Ha'o journeyed to Samoa with her teacher, pwo (master) navigator Kalepa Bay­ba­yan, to fulfill a promise to her grandfather that they would all eventually meet in Faleapuna. To get this far, she helped navigate Hokule‘a across some 700 difficult miles of Pacific ocean, against some fierce winds.But far more difficult than the winds, she said, was leaving behind her husband and three small children, including a newborn girl, back in Hilo so that she could complete her monthlong trek.\It was not an easy sail
