Looks pretty good but do you want that jog in the roof?  Why not a flat roof all the way.

My thinking is I need that room for the battery.
Here is a couple of pictures of different boat. common trait between cabins and engine rooms...........None.

Here it is with the roofs laid on. Now remember, doors and windows have to be cut in, exhaust pipes etc etc. The center pic shows the location on one of the net booms.

I didn't mean to chop it off, keep the existing length but make the roof line straight.  Than would give you more room for the batteries.

I see there's nothing the same about the roof of any two boats, only the Stephanie had a straight roof on her cabin.  So does Miss Peaches for that matter.  ?So which ever way you go it will be scale since you can find a shrimper it will look like.

Here is something else I just checked.
If I put a 4" door in the rear section or for that matter one on each side and then install another 4" door near the helm area the scale looks to be about the same. In other words the roof line is maintained.


I'm not sure I explained that right. but what I'm trying to do is maintain the aspect ratio.

You have a sloping foredeck which actually makes the door placed forward appear larger when compared to the one in the aft area.  I think, not positive, the foreward door needs to be both shorter and narrower to maintain perspective?  Have to look around at other boats to get an idea.

LoL
The rear cabin has bunk beds and needs to be taller.
Problem solved!

Front door shortened and a bit narrower. Remember these are just for reference.

I think the height looks good.  Just for 'giggles', don't change the height, switch the two and let's see what it looks like with the wide one on the front.  Do you have some card stock?  You can cut some doors and save wood; have two wide, two narrow, one of each tall, one of each short, mix and match and see which ones you think look best. 

I personally think the perspective is right with the current height but the width of the doors don't have to be the same.  It's going to look better one way vs. the other.  Just have to plya around with it  a little.  With card or paper you can make the wide one narrower or the thin one wider but not as wide as the rear one - you know what I mean.

Great idea about the card stock. on my way to work right now, i'll see what I can find.

Default RE: Scratch Built Shrimp Boat.

Changing gears a little,
I plan on using 12 volts for the motor along with a good ESC that can operate using the 12volts.
Having never tried anything like this, I would like to add working navagation, Flood and work lights along with interior lighting to the boat. thought it would be neat to run it at night.
In order to make this happen I have to step the voltage down to 6 volts.
I found that Harbor Models has a unit that will reduce the voltage, But its a little pricey at $120. Are there any others that will do the job?
Going back into the memory I remembered this site.
http://www.dimensionengineering.com/DE-SW050.htm
And this.
http://www.dimensionengineering.com/VregBreakout.htm
Now if I'm reading this correctly, the unit will take any voltage up to 30 volts and step it down to 5 volts. which I'm assuming I could use for a 6v LED.
Or this unit,
http://www.dimensionengineering.com/SWADJHV.htm
which will do the same thing, but the output voltage is adjustable.
So, am I reading this correctly?

First thoughts about door and window placement.

On your door and window placement, first thought, looks pretty good. The rear door will be taller won't it?

O.K., question before I comment on the lights. Are you going to use LED's or 'grain of wheat' lights? Mixing them is possible but maybe not a good idea. If you are using LED's and no other operating mechanics to begin with, you don't need a step down transformer.

First question, door. Not sure yet, I'll make a taller one and see how it looks.
Lights, to be honest, I didn't know about the grain of wheat lights.
But my plan was use only LEDs. I think they would look better because if the flood lights that will light the deck.
The LEDs from the link I used are 6v operation.
As far as other operating mechanics, the only other thing will be the booms for the nets. But they will operate on sail servos that will run from the radio gear.

In that case, you can use a dropping resistor to provide the correct voltage to your LED's. If you have more than one of the same size, type LED you can wire severa in parallel nad use just one resistor to drop the voltage and give you the correct current.

I can do my own stuff without a problem but would probably step all over myself trying to explain it correctly so I hope there's an electrical type person reading this thread who will jump in here and help out.

Grain of wheat are the older way to go, but they work real well. LED's have a MUCH longer life .

If I used the LED's and controller from the above links I would not need to wire in any resistor's, Correct?

Second door placement. Different style door for the rear and a smaller window.

If you buy the one from Harbor Models you will have your 6V plus some other voltages.  Of the other two, one gives you 5V output and the second one can be adjusted to the 6V you need with a limit of 1 A.  Since LED's "typically" draw 30 to 35 mA, you can run a lot of LED's off of it.  (I'm not familiar with 6V LED's, I'll have to check them out in the morning)

I notice they can be run in parallel which is very good, especially if you happen to have a lot of LED's.

Where would you get 6 volt LEDs?

Most LEDs run at a lower voltage.

http://www.rcgroups.com/forums/showt...d#post17704307

Look at post 20 & 21.

Also, once you know the LED's specs from the manufacturer you can go here:

Those are pre wired and the resistor is part of the assembly, it doesn't get much better than that.

That's what I'm talking about.
Then I could use the regulator to dial down the voltage for the brightness. I think?

I just Received an package in the mail from Larry. LOL. I just about fell out of my chair when I opened it.
Larry, I will find a place to put this, count on that.


Thanks Larry. My first seagull.
