numbers on my sons seafari 25
 

we installed some electronics on it and took it out sunday. we had about 70 gallons of fuel and 5 people on it. I played with the trim and was able to get 5600 rpm and 35kts at wot and 26kts at 4400. she is a wave crusher but pretty hard to keep level, I was constantly moving the trim tabs. if you did not see the other thread it has a 225 etec on a notched transom.

Thanks for the post and the numbers!! That's pretty darn good for a big single with 5 people on board. As far as Trim Tabs and constant adjustment . . . here's an email directly from Bill Potter (back in 2007?)

"Hi Tim,
Please tell Strick he has the best riding SeaCraft we ever built. It is not a boat for someone who doesn't know how or doesn't want to use trim tabs and the power trim of the IOs or outboards to get the most out of the hull design. The boat has the deepest V (25degrees) of any SeaCraft and, due to having no lifting strakes, it is more sensitive to "leaning" in cross winds and from weight shifts while on plane than other SeaCrafts and other deep Vs. BUT, it is like flying an aerobatic plane, if you know how to use the trim you can set that boat up to run through anything you have the nerve to be out in with remarkable comfort and safety. AND, because of the Variable Deadrise Hull design it is a very stable platform at rest or at trolling speeds. I wish we had a recording of the story a guy told us about his run from St Croix to St Thomas during a major hurricane flying through and off 25 ft and larger seas in the dark! Pigs don't fly!
Best regards,
Bill Potter
ps A SeaMark twin Fiberglass Bracket and properly positioned and operating trim tabs would be my recommendation unless he is going to go with a big single diesel duoprop stern drive or smaller twin duoprop sterndrives. ( Duoprops minimize torque roll)

Good numbers. i'm a little surprised a 225 would do that well.

The 25 is, for sure, a drivers boat, and, oh boy, does it reward a skillful driver. It took me a couple of trips to learn how to get the best out of it. Its easy to drive once you get the hang of it, but it still requires attention if its snotty.

I agree that's better than I would have expected, but most E-TEC's are strong running motors. That "225" is really about 240 hp at the prop, with lot's of mid-range torque and probably at least 500 lbs less weight than an I/O, which probably explains the excellent performance!

The ride is other worldly.

Why I love 2 strokes.
Torque baby.
And where you can use it.

The G2 250 has 600 ft. lbs.
600!

putting the 23 next to the 25 . . . 25 is about 1ft narrower than the 23 and about 1.5ft longer. The hull weight isn't much different either.

Good numbers OP. Lets just clarify on the G2 Torque. Yeah it has 600ft lb AFTER accounting for the gear reduction. Not even a 3l diesel has anywhere near that torque AT THE POWERHEAD.

Bs,
Are these waterline measurements? Interesting.

1.5 feet longer sounds about right, but the beam on my 25 is real close to 8 ft, probably exact. Isn't the 23 also 8 ft?

I've stood next to all three, 21,23, and 25 together, in the water. There is surprisingly little actual difference between the three, way less than you would think. In terms of usable space, Moose's 23 Septre is far bigger than my 25.

I measured my 25 above the above the waterline (where I'm mouting a bracket) at 82"
Roughly the same area on the 23 is 90" if I remember correctly. I can measure again tonight when I get home.

Not the same, the 25 is actually about 6" or more narrow than the 23' hull. I had a bracket off a 23 and placed it to the rear of my 25 and it hung past the sides about 3" each side. At least the transom is narrower, I don't know about the max beam at the widest point but know the rear is narrower.

The performance doesn't surprise me I was getting 46-47 mph (40 knts) wide open with the 27 foot seacraft race hull with an old wore out 225 mercury. Im sure it is much lighter than the 25' but 35knts is still awesome for the seafari.

Curiosity will kill us all eventually. I just measured the water line at the transum, 82 inches, just short of 7 ft. Sure doesn't look like it narrows down that much, but it does. Now wonder this thing runs like a knife.

I always enjoyed this quote from Moose...
Here are a few pics from the meet. The first one I call.... "21 foot my ass" As you can see, Terry's 21 towers over my 23 Tsunami!

we took it tuna fishing for the first time this past weekend and it took the seas great we are still trying to get used to how it leans every time we turn even a little bit.

You will; your kidneys already have. I hardly notice anymore, but try to remember to warn new passengers so they don't freak out.

The boat will do some funny stuff. In flat water (don't try this when its jumpin and don't ask me how I know), if you turn very sharply, the boat lays over until the keel loses its grip on the ocean and the boat will actually spin. Still feels totally in control (in flat water). Makes for a very tight turn.

You can use the boats sensitivity to lean to keep the keel perpendicular to the water surface when its rough. Bringing it down onto a wave perpendicular makes it even more comfortable than it normally is. Takes a little learning, but brings big rewards. Just a slight twitch is all it needs.
