Bracket design question

[Bay Runner]

Ok guys, here is a question for the brain trust.
Has anyone thought of making a bracket for a 20sf that is an extention of the hull and wide as the beam, making the hull about 26 to 30 inches longer(depending on motor setback) and putting the trim tabs further back than a conventional floatation bracket a little more bouyancy than a conventional bracket to offset the weight of the motor.

good question - I've had the same thought - sort of building a euro-style transom onto the back of the boat, carrying the hull lines back. Have to admit, I was thinking about 20 - 24 inches would be about right.

Really shouldn't be terribly difficult - pro's and con's ???

If you want the performance generally attributed to brackets (2-3 mph) due to being able to mount motor higher in clean water, you might not want it to come all the way down to bottom of hull. Maybe leave a 2-3" step, sort of like a stepped hydro.

If you carry the line of the bottom of the hull back, your really defeating some of the advantages. You have more surface area/drag where it contacts the water on plane, and your just creating disturbed water off the back by the motor, defeating that benefit too. If your going to add 30 inchs, you might as well get a 23' hull. The only advantage you will gain is closing in an open transom.
That's just my opinion.

And look at the design of most of the current crop of "extended" hull boats....like Scout, Contender, etc. There was a thread about this time last year where I posted photos from a local boat show. Most of these boats look like they simply permanently attached a bracket. One the Scouts was even done in three pieces. They all had the hull extensions up a couple of inches from the hull bottom.

I guess another part of the question is, if the full beam width bracket(transom extention 24") was held up 2-3 inches, wouldit give that much more bouyancy at rest than a double flotaion bracket like hermco or armstrong.

Yes there has been talk about doing this a few times that I can remember. But no one that I know of has done it with a SeaCraft. I think that it could work very well, but just adding a good flotation bracket works well with out that much work. One of the problems you would face is dealing with your trim tabs actuator assembly if you ran the flotation chamber to both ends of the transom.

This is a SeaVee transom that would work easily.



On the Condender they notch out a section in the bracket for the actuator assembly



I think we are all guilty of wanting to grow out boats 3 foot or more but the Best way of doing it to start with a 23 footer and making it a 20 footer inside with a hull length of 23’ in that way you got the hull length you want with out all that extra work. But if you did have a 23’ like I do you would be thinking of how to make it a 26 footer.
Why did God make us this way???

It's the FATAL affliction of fin chasing, water worshiping, ocean air breathing lunatics-- TWOMOREFEET-itis!
...there is no known cure, just TEMPORARY symptomatic relief of the cravings at a VERY high cost to one's wallet!!
...think of the guy whose boat was grounded on the sandbar off Key West in the other thread-no one can comfortably AFFORD that much pain!!!
