Looking at buying this boat. Is it the same hull as the SF and MA?
Does it have the fiberglass stringer system?
Looking at making it a center console

Best year of Seafari. What a waste to cut it up, IMO. Yes, glass stringers. Same hull, different liners. What a waste to cut one up, IMO. Plenty of SFs in SE USA. You'd save a bunch of time and money finding one on CL between NJ and FL and towing it home.

^^^this. Please reconsider. Search a bit more, you'll find the right SF/MA that someone ELSE has redone. Save you time and money.
The Seafari is a special boat, wonderfully engineered.

It's spelled Seafari, and butchering one to turn it into a CC is a bad idea for any number of reasons, particularly from an engineering perspective, but that doesn't seem to stop amateur naval architects from proposing it about every 6 months! Not only is it MUCH cheaper and easier to just buy a center console model, of which THOUSANDS were made over about 25 years, by SeaCraft Industries and Tracker as well as Potter and Moesly. Only 741 Seafariís were built for over 10 years, only by Moesly and Potter. As others have mentioned, it would be a shame to destroy a relatively rare and uniquely versatile model to turn it into something thatís so common.

As Gillie said, there are some differences between the Seafari and CC in the cap/inner liner, and those differences are there for some VERY significant structural reasons. I always wondered why the CC models didnít have the under-gunnel rod holders and handy shelf in the back that runs the entire length of the cockpit in the Seafari, but I think I finally figured it out. The cabin top, bulkheads and raised 6.5í cabin bunks in the Seafari add a LOT of torsional stiffness to the hull! Since the CCís donít have any of that structure, the only way they can attain some (but probably not all) of the Seafariís stiffness is to create a box section in the back of the hull by closing in the inner liner! (Some CC owners that have ridden in my boat in rough seas have said it feels a lot more solid than their CCís when punching into big waves, and now I think I know why!) The CCís do have the raised casting platform up front that compensates for some of stiffness lost by opening the sides of the inner liner up forward for rod holders. However I don't think that configuration has nearly the torsional stiffness that you get with a full width cabin top supported by a couple of ĺĒ plywood bulkheads!

So youíre proposing to eliminate all that rigid structure in a hull that DOESNíT have the box section in the back of the inner liner? I think the result will be a ďwobbly noodleĒ in terms of itís torsional stiffness! Take a shoe box with the top taped on it and try to twist it. Then remove the top and cut out one end, and twist it again, and I think youíll get the idea.

I suppose you could try to stiffen the hull by increasing itís thickness by adding some balsa core and extra glass above the water line, or even foam core if you use epoxy resin and vacuum bag it to insure the foam bonds to the hull. This will significantly increase the bending strength of the hull, but it wonít do a lot to increase itís torsional stiffness. That full inner liner in the back of a CC essentially creates a hull with 6Ē thick sides, and coring the hull to make it 1Ē thick obviously wonít be nearly as stiff as one thatís 6Ē thick! Sort of like adding some corrugated cardboard to the sides of the cut up shoebox.

Now I know that SeaCrafts are seriously overbuilt compared to most of the competition, and I suppose that even one thatís been badly butchered is still probably more robust than the average Bayliner, but why start with a superior design and turn it into something thatís just ordinary?! To this old engineer, that just seems wrong on so many levels!

Hey Denny, you should copy/paste this reply into a word document. It will make it easier to use as a reply the next time this comes up........and I'm sure it will. Take care Sir!

Hey Don,

I WROTE it in MS Word first! I've lost too many CSC posts because I hit the wrong key, so I started using MS Word for a long winded post, which many of mine are, then cut & paste! Denny

"Great minds think alike"....well maybe your mind, not so much mine. However I'm with you on the copy/paste from a MS word file, it's because I'm lazy.

Seacraft84 is also my username. My father posted the question. We were not sure if it had fiberglass box stringers.
Not sure why people get all upset over turning a cuddy into a CC. The dang things arent gonna sell anyways. Who wants a cuddy that will not selfbail with todays motors on them?? Yes put a two stroke on it, but then who wants to buy it?? No one... Plus it still wont selfbail.
As far as a amateur naval architect, not flying this thing to the moon, so im sure alittle glass and resin will make it "stiff" enough for here on earth....Fiberglass work is not rocket science.
And no liner will be in any seacraft that I restore again. Takes up room. My last MA was plenty strong w/o a liner. Tightest seacraft ive been on.
Next project will be to take one of these superior designs and turn it into something extraordinary. Im sure everyone is gonna love what we do to the next project.
I will be more than happy to save the cuddy liner for anyone who wants it. All I want is the hull.

I figured that out a while back. Thought one was you and one your father but after reading threw a few post realized you must post with both of them. Is that seafari the yellow one that was on c.l. awhile back? I tried to go to Morehead to get a yellow one for cheep but it sold before I could get there.
