I checked on shipping a Stonehorse 23, about 27' overall to Hawaii last summer. Seem to remember Pasha gave me a quote of around $5,000. Matson's first quote was in 5 figures and came down to around $7,000 with a bit of discussion with someone farther up the
food chain. Matson is all on cube so if you are talkiing a
trimaran expect to spend a fortune. Don't know about Pasha's pricing.
I got Matson to come down on their shipping going through the backdoor with
advice from one of the TransPac
race organizations. They had made arrangements for a bulk shipment of the
race boats back to the Mainland from Hawaii that was way way lower than Matson quoted me to Hawaii. I talked with the guy at Matson who had set this up and got a cheaper rate to the Islands. Still was way more expensive than Pasha. Unfortunately, didn't keep any of the information on who I talked with at Matson.
If you are talking sailboat, or even a
power boat, it's probably cheaper to bring it over on it's own bottom.
