23 floor job

So seriously, does anyone want to chine in on my thought of adding 4 feet to the back of this boat?

Give it a try, The guys on classic Mako have done it a few times with good success. I think it would be cool with a euro style transom like something similar to ones like they put on the newer boats today. Long as you get the center of gravity right and make sure it is done correctly I think it would be ok to do. Lots of unknowns but it has been done before on many other boats. If i would do it I would make sure the stringers were extended all the way threw the new section and make it strong as possible. This would be a large project to take on but I think it would make for a fun project. The worse thing that could happen is it might ride like crap but I think you will be surprised and it might preform better than expected.

not a good idea for a whole lot of reasons. You might want to read a couple of books on hull design to completely understand why.

You have one of the best small offshore fishing boat hulls there is, dont try to re-design it

Shine is probably right, the boat will not ride well as the proven factor design. I would like to see some one do this modification just so I could see how it turns out. I have thought about making a euro transom for my 23' cc but would only go back about 30 inches or so. This would be similar to a bracket but would be all one piece and made to the boat with stringers extended all the way to the rear of the extension. Anything over 2' feet or so would probably cause some issues. I think that the bracket would give the motor cleaner water for the prop but the euro would give the boat a better span over the water with the extra length being used vs out of the water with the bracket. The 4' you mention would be too much with the narrow beam but if you wanted to still do a length mod I would go shorter if you wanted to attempt still doing this. I am afraid to do this myself and you would make a nice guinea pig but there seems to be many more cons than pros but if it worked out well you would have one cool rig! There is just to many ways for it to go wrong for me to try it with out someone else first doing it. It may not work as well on a seacraft as it did on the makos that have been done. Also the guys that have done this clam it to be great but hard to go by their opinion. They might be bias and if you think about it they might not talk crap about their work if it turn out to ride like crap. You might be better off looking for a 27' seacraft super fish. Not many out there but you know that it would ride like a dream.

thanks shine and flyingfrizzle for the input. i'll have to take a look at the classic Mako guys that have extended their boat. i definitely wouldn't want to do it if wouldn't ride as good or better. i'm just looking for a little more room. With 4 divers and a bubble watcher and 12 tanks on board, it starts to get a little cramped on the 23. If Potter would have just designed a 26, that would have been perfect for what i'm doing. Even 2 feet would add a lot of room, but if i figured on cutting the back of my buddies boat, i may as well add 4 feet. i was also thinking to just put my transom back on the donor boat and turn it back into a 19.5 footer. i wonder how that would ride? And the 27SF is sweet alright, that might even stress my Cummins in my truck. The 27SF is just a little big for a trailer.

I don't know and wouldn't want to do the work just to find out, but why do most people think it's okay to completely screw up the boat's intended design with a bracket? I imagine you could get 4 feet by adding 2-3 feet of running surface and 1-2 feet of bracket surface. One great hull made better by adding 2 feet comes to mind: Formula 233 to Seavee/Whitewater 25. Nobody is going to argue that the original rides better than it's stretched cousin.

I would give some thought to center of mass and stringer stiffness and strength before I grafted on 4 feet. The 23 isn't considered wide, and as a 27, it certainly wouldn't be.

There are a few 25 footers around. (Not stretched 23s) They are cuddys, but they can have a bit of floor out back if you don't litter the space with chairs. But either option- 23 stretched, or a 25 with it's 26 degree deadrise, would likely roll at rest. Which might not be great for a dive platform, but maybe good for getting there?

Well it has been a while since the last post. It isn't that I haven't been working on the boat, but been too busy to post any pics. To bring everyone back up to speed, the following has been completed. T-Top/outriggers/antennas installed. E-box installed, just need to re-terminate two wires and install bottom machine. Console and new windshield installed. Most of the wiring under console has been completed. Need to install 21 gallon freshwater tank and battery box. Sweet, bad to the bone dive ladder has been installed and I would guess it would load test a four hundred pound fat boy easy. Fired the YoMAMA up after 15 months. It idled a little rough, but after an overdose of SeaFoam she is running much better. Anyone want to donate their gas sipping outboard to the cause? Still need to install the leaning post, fix some wiring to the trim tab pump, and plumb the bait well. She is getting closer, wish it was already finished!

A few more pics and I almost forgot, I need to paint the engine cowling!
