Series I 60’ EB refit

So, I’m the captain on a 1980 60’EB that had a major refit in 2010(ish) that neither the current owner or myself were a part of. Recently the subject of repower or sell and start new came up and the owner has decided to refit. He’s well aware he will be putting in more $ than he will ever get back but his stance is he never wants to sell it anyway so he’s ok with that. I’m in the initial stages of putting the project together with the goal of next winter. It seems most of the old school Hatteras refit guys are retired or MIA and was wondering who you guys would recommend to help with this one. We are running DD 12v92 DDEC’s currently and are kicking around the idea of C18’s which are the same hp but much lighter. We are open to other options though. Also planning on removing the unused tower to reduce drag and lower the CG. I’m looking at stabilizers and possibly lifting rails but haven’t really started my research there yet. I’d love to know what the hull speed of the series I is. I’m guessing chasing HP is possibly pointless, but I’m not sure. The last refit was done at Saunders and without getting into it, there have been enough issues with the work they did to consider using them this go-round. Here’s a few pics of how we sit now…

Sorry for the sideways pic….not sure how to correct that

I've been on and worked on a 1978 60 open bridge for the last 15 years. This boat has Naiads and they work great at cruise speed but are only 4.5 sq ft fins and are not as effective at hull speed. I would think 6sq ft fins would be more appropriate and effective. The tower was removed from this boat as well during refit.

Viking Boat Works in St. Pete. Did an excellent job on repowering my previous 52 with Cat 3406Es

Not knowing how you use the boat, but for me c18 wouldn't be enough power in a 60 enclosed.
If CAT would go with c32's, I'm a CAT guy but have noticed a lot of repowers of v12 and even v16 2 cycle Detroit boats are putting in 10v2000's m96 MTU's @1500hp, or so.
A 64' Merrett was recently repowered from 16v92's to 1500hp 10v2000's and picked up quite a bit of speed burning far less fuel, besides opening up the ER.
So, I guess I don't really understand the stabilizer thing on a sportfish, why not a gyro instead?

Re: Series I 60’ EB refit

So our current 12V92’s are just shy of 1100hp each. The C18’s have a 1150hp version that are 2000 pounds less per engine. I’m not sure chasing more hp is worth it on a series one as hull speed would be the limiting factor. As for the stabilizers, zero speed fins will do about as good as a gyro at rest, without the need to spin up. Unlike a gyro though, they work even better at speed. I saw a video link here where a Hatteras engineer explained they had been experimenting with fins up front, which lift the bow, combined with interceptor tabs, which lift the stern. Effectively they were “tricking” the boat into running like a lesser displacement vessel. I find the theory intriguing but I’m just starting to look more into this. I’m currently looking at Humphrees fins and interceptors.

Re: Series I 60’ EB refit

First off, good looking boat, she had a tasteful touch.

I have nearly the same configuration (1000hp Pre-DDEC 12v92) and the same questions... Having spent considerable time researching the performance of the 60 I vs the 65, the issue appears to be largely a lift problem. The 60 I has narrower, flat chines vs the wider downward ones on the 65. Given the same power the 65 is considerably faster, and has a much higher speed ceiling. If you ever run your 60 in very shallow water, you can see 1 to 1.5 knot gains due to ground effect.

I've seriously considering re-sculpting the lower chine to a downward profile. The massive keel the 60 I has vs all later models is also a limiting factory, but not tackling that.

Please keep us posted on the refit! Would love to see results.

Curious what your performance numbers are? We get about 23 knots top with a load, full tower, little taller than yours. That said, I do have down angle ZF gears and the engines sit much lower and forward of the factory config as seen. She was refit in 2007, and my understanding is the owner wanted more speed, had single piece shafts installed on less angle.

Is that the former Silver Streak?

The same! How did you know? We brought her to Alaska last year. Anything you know about her; I'd love to gather. Absolutely love the boat.

My neighbors boat here in Vero Beach Florida all its life always Captain maintained with an open checkbook. He and his wife spent a lot of time in the Bahamas on the boat usually was gone for 3 months in the summer. They had 2 black labs that could climb the ladder to the bridge and they slept up there when they were on the boat. The boat was a permanent fixture across the harbor from me for the 34 years I’ve lived here. Bill had one of th largest citrus operations in Indian river county and all his trucks were silver. Hence the silver streak because his guys drove fast you didn’t get in the way of a Becker Citrus truck. Sadly Bill had a stroke a few years ago and his wife sold the boat. His captain Bob worked for him since the boat was new. Great people that we really miss. I was away when the boat was sold I would have bought it in a second if I knew. You got a great boat that was dearly loved.

Re: Series I 60’ EB refit

I would go with 1800hp C-32's, or better yet reman 3412's @1400hp, C-18's are too small for that boat.
If everything is perfectly clean and I'm a bit light on fuel I see 26-27kts using 1000hp/side, but my boat is an open bridge with a minimal half tower, no stabs and modern props.
If I re powered with either of those I could cruise 25 kts at any weight using 1000hp per side and the engines would last practically forever.
However my J+T hot rodded 1271's are crisp running healthy examples, so unless the engine fairy visits my pillow.....

Re: Series I 60’ EB refit

You can only push these old hulls so fast. They were designed by Hargrave to run 16-18 knots in nearly any kind of sea. Start cutting keels and modifying other than lifting rails at the chine your going to ruin the seakeeping abilitys. 65 is much faster but as those of us that have fished on them and are HONEST will tell you in any sea other than a head sea they don’t tract well and are a handful to keep on course.
