Free of charge — send us your request for Hochiki equipment. Our team checks it and replies by e-mail.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — attach it below or send it as a reply to our confirmation e-mail.
