25 seafari conversion to CC

[Bigshrimpin]

I floated my 25 without power a few times (and broke Strick's 25 once) . . . The hull definitely NEEDS weight. Strick scared the Sh#t out of me the first time he banked the boat at speed.

I've been told the hull needs weight (down low) to sit right in the water and not just weight forward. I got to discuss the 25 hull with a former Navatek employee that worked on the 25 project for 4 years. He lives in MA now (his wife still works for my employer). He wrote Matlab code for measuring the ride in quantifiable numbers, put thousands of hours on the hulls and talked in depth about the different configurations at Navatek.

"adequate stern weight" was something he mentioned . . . Steven Loui also used those words in a post.

"With the big block sterndrive giving it adequate stern weight, it runs much better than the other two SeaCraft 25s I have that were originally rigged with a smal block sterndrive and the other that I retrofitted with a single large outboard on a porta-bracket"

Connor and other owners might be able to shed light on their configurations.

Thank you! I had seen the add before BigFluke purchased it. This version with bow fish box filled with ice for weight and the sterndrive seemed the best compromise. Cap looks well integrated also. Hope this ones turns out great. Super project.

I’ve ridden in Connor’s 25 in 5-6’ swells. Very soft ride, and like all Moesly designs with original-type power, it would plane at relatively low speed, like about 12 mph!!

Banking like a jet fighter is fun once you get used to it. The hull will actually spin if you go over far enough. Experiment with it and you discover that you are still in complete control. Odd but true. Warning your passengers is a good idea. I did have to play with the tabs if people moved around. You get used to it.

My configuration was was pretty good, small block duoprop was much lighter than the original twins and balanced the lack of ballast tank fine. The boat handled fabulous as is. It was even better with lots of weight added forward. When going on a long trip, with the forward hold full of water and as much weight forward as possible, it rode even better, bow down slightly and somehow seemed more stable. Not sure how to quantify that, just a feeling.

As I ran it, it was the most seaworthy hull I ever experienced. It didn't matter the conditions the hull felt rock solid, big, short following seas, tropical storm conditions on the beam, anything I ever experienced, A look around might scare the sh#t out of me, but the boat never felt like it was anything more than a walk in the park.

Screw with the cg too much and it might feel like a different boat.

I bet it drives just like my dads Bertram 20. You can nearly dip a rail turning in that boat.

started on stringer repair on the 23, they were both blown out at the bottom and need lots of love, also got the 23 transom tabbed in, old through-hull holes patched up, and 25 transom cut and glassed on both sides, quick sand and its ready to go in the boat

[wgscott329]

stringers on the 23 have been getting some love and are almost ready for new foam, transom of the 25 is ready to be installed hopefully by the end of the coming weekend

Are you planning on building the grid stringers like your other 23? Coring the sides?

[wgscott329]

This one will have a partial grid to allow for some deck hatches port and starboard in the rear, but I'll be keeping a good portion of the original stringers towards the front of the boat. The 25 is getting a full grid with lots of hatches.
