    How much fuel does this 70′ use at 30 kts Volvo Penta with the IPS on a 70′ Spencer burns 134 gal ph at 38 kts and 108 gal in the artical in Marlin and on the Volvo video they said they burned 98 gal ph. I think the differts was the weight. Volvo compeared other 70′ but they weigh 30,000 more then the Spencer. So I would like to see the numbers.

    What are the lead times from board to launch. Thats a very open question. Im looking at some of the larger production sport boats. Without naming names you know who they are. I want between a 70 and 80, safety first, durabilty in materials, then comfort. if you could kindly send a link to other photo’s of your current work that would be appreciated. Thank you for your time.

      Have you built any boats with Zeus Drives in it?

        Hi Jordan, yes our most recent launch, the 46′ Convertible, is powered by Cat C9s with ZF pods. We also have in-progress 43′ for sale that is designed to be powered by pod drives. Please let us know if we can answer any further questions – we love talking about boats!
