70′ IRON LEADER
- Custom Hull #
- 48
- Splash Date
- June, 2008
Originally commissioned by another engine manufacturer as a test platform for 2400 HP motors, resulting in a top speed of 49 knots, Hull 48 underwent a repower in 2021 to field test the first pair of high-performance C32B 2433mhp engines in the U.S. We are honored that our custom hulls are the choice of leading engine manufacturers and serious offshore anglers alike. We can’t wait to see where they’ll take us!

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.
