We bought this boat seven years ago because it is a great layout for a trailerable boat. Since then we have made a few mods:

Top re-configured from a Convertible to a Bimini. Gives a better view, more air flow and I believe a little bit of an updated look. First, I traced an outline from a picture of the boat and then drew in what I wanted the top to look like. One issue is where the new top should stop. For that, I applied the golden ratio as you will see in the sketch below:

Also, I had to move the mast light from the middle of the windshield to the top of the radar arch. I discarded the old light, ran the wires up the arch and attached to a new mast light. Additional SS framework had to be made for the new top configuration. The front rail is permanent, so, zippers were put in the top pockets so that it can be folded back or removed. An eisenglass windscreen and side windows had to be fabricated:

Next, since I had a new top configuration, I could have a full, over the winshield, cockpit cover fabricated.
Also had eisenglas "windows" put in the aft part of the top for the lights in the arch:

Next was replacement of the am/fm cass. radio with a xm ready radio and 6-disc cd player. Owners of these models know that the radio is in a shelving unit. The radio was placed in the unit with a open shelf below it. I filled the whole space by cutting a piece of maple(?) and then covering it with Black Formica. I then cut out for the radio and CD player:

The old interior materials had to go, so we re-did everything in outdoor (sunbrella) type of fabrics. (Sorry about all of the pillows - wife, you know):

I just completed an install of a new TV/DVD player and Shakespeare SeaWatch 2025 antenna.


This is my system:
-Naxa 19” TV/DVD player.
-Articulating VESA wall mount
-Shakespeare SeaWatch 2025 Antenna
-Shakespeare 4365 Straight antenna mount


Naxa TV: Digital HD with built in DVD player. Comes with two power cords. One cord is for 12VDC and has an accessory plug on it. The other cord is for 120VAC and has a “brick” on it. I used the 12VDC cord, cutting the accessory plug off and direct wireing it to a 12V source. (Note: there is a fuse built into the accessory plug, so if you do as I did, you have to add a fuse in the power source line.


SeaWatch 2025 antenna: This antenna comes with an rf pre-amp. The pre-amp can be purchased separately for about 100 bucks.


My results: I first hooked the antenna cable directly to the TV and then took the boat out in the lake and did a channel scan. I was able to lock in nine (9) channels. Next, I wired in the rf pre-amp and took the boat out to the same spot in the lake. With the pre-amp I was able to lock in nineteen (19) channels. For reference purposes, I am on a lake which I would guess is about 30 miles out of Atlanta, GA and 40 miles from Rome, GA. I appear to be picking up all of the Atlanta and Rome stations. (Of course, reception is dependent on location)




Antenna Pros and Cons: I liked that the cable is fed to the antenna thru the antenna mounting pipe to the center of the antenna. This helps to shield the connector from the elements. I did not like that Shakespeare provided four (4) carriage bolts and lock nuts to secure the antenna to the mount. I would suggest that you purchase four(4) 1/4”x1” SS bolts and flat washers and use them instead of the carriage bolts. This is because the carriage bolt heads mate into the plastic female counterpart on the antenna mount and the plastic can easily be stripped out when trying to tighten down the bolts. Eliminate the problem up front by getting rid of the carriage bolts.​




Rf per-amp Pros and Cons: Pro:It can be wired for 12VDC or 120VAC operation. It can give you up to 20db gain and it does work! When it is on, it automatically selects the antenna as it's signal source. When turned off, it automatically selects dockside cable as it's signal source. It can be purchased separately and added to an existing antenna system. Con: It is large, unsightly and limited as to where it can be located. I would suggest to Shakespeare that they make a model that separates the gain control, on/off switch and indicator light out from the rf pre-amp. That way the rf pre-amp could be made a “black box” and mounted out of sight. The controls could then be be mounted on small face plate and mounted where they are convenient to the operator.​

Here is the procedure to make that "bushing" install to make your job look neat:
Ok, you have to bring TV cable and a power cord thru that upholstered panel that the TV is mounted to. As you know, that makes a messy hole in the panel. To make that as clean as possible, I put a bushing in the hole to dress it up and to protect the wires.
Details:
- After deciding on the location, I drilled a small pilot hole.
- Then, I stuck the point of a 1" spade drill bit in the pilot hole and turned it while I made a trace of the circle. (You, of course, could do that with a compass)
- Using a sharp knife, I cut around the circle and removed the vinyl and backing material.
- Then, I drilled a 1" hole in the panel.
- I bought a bushing (specifics below) and forced it into the hole.
- Looks good, no ragged upholstry edges and the wires are protected.



Specifics on the bushing:
- Home Depot SKU# 34481 06262 2
3/4" PVC Adapter (Electrical Dept)
ID is 3/4", OD is 1 1/16".
(So, you have to wiggle the spade drill around a little and tap the bushing in with a hammer

Great Job!

I have been wanting to do that to my top for years but I haven't pulled the trigger. Did you have that done locally? or did you do it yourself?
 
There seems to be an issue lately with pillows? Is it the weather?? Nice upgrade BTW!

Had it done by a canvas maker outside of Knoxville. He fabricated the new framework and did all of the canvas work.
 
Nice job! Really like the interior upgrade. What a difference!
 
Wow! Exceptional!
 
Great to get a :thumbsup:, from a fellow Allatoona boater.

Wow great job, I like that interior. I plan on updating mine next year. I added a swim platform (love it) as you can see in my sig. pic. I also put in a 19" flat panel and upgraded the stereo with a new head unit, polk speakers, and a powered sub. I also put in 5 stainless cup holders and added some LED lighting in the cabin. Added memory foam to the beds....it never ends!

Quint, can you provide specifics on how you ran the 120V line and what you did for the antenna input. I want the TV install, but, also a DVD player since when we cruise, we are usually away from the civilized world. Do you have an idea for a DVD player in addition to the TV. What brand flat panel TV did you use?

Also, I was looking at the steps this morning and am wondering if those can be removed and replaced with solid wood steps. I thought that I saw a screw head in one of the risers. Do you know if the risers are just screwed into place? (I didn't have enuf time to really investigate.) I see a possibility of creating storage under those steps by putting a draw into each of the risers.

I can't put the extended swim platform on right now because I'm on a lift and would have to have the lift moved forward. I would do that, but, we are seriously considering taking the boat to Clayton, NY, using it during the summer and then leaving it in storage there. I'm getting to ancient to hustle that mess up and down the highway - and, I'm not parting with that boat. If so, then the extension will go on. Do you have any prop wash issues with that? Do you bring your Zodiac up on that? If so, how and could you post some pics?

BTW: Here is link to our web pages if you want to see how we use the boat: http://sites.google.com/site/rideaur/rideaucanalhomepage

Jerry,
I am at work and will post pics when I get home tomorrow or Sunday. Short answer on TV is I used a standard VESA mount. I cut off the 120v converter brick and wired it straight to 12v....it is a Polaroid brand and has a DVD player built in. Dinghy pulls up on swim platform and I tie it off to cleats....pics in a day or two.
 
Jerry,

I see where you pulled the 12V line, down past the water pump, etc. Having a hard time even finding anyone that sells that TV. Any info? Actually, we had not even thought about a TV, but, would like one to watch DVD's. I really don't want to see all the crap that is on TV.
I looked at the steps this am, it looks like it is just plywood that has been screwed down and then carpeted over. You could probably cut the carpet out from the steps and risers, and then do whatever you wanted to do.
I am concerned about the added weight on the back of the boat from a swimplatform and Zodiac. Is this an issue for you?

We mainly use the TV for watching DVDs but do get some local channels at the dock. The cabling for the TV penetrates the bulkhead it is mounted on and is routed under the dash, into the starboard gunnel, into the engine room, then to mid-cabin closet to 12V and antenna hook-up. I bought the TV over a year ago and the model may not be available now.
I was worried about the weight of the swimplatform but it is negilgible even with the dinghy. I probably run another 100 rpm.
Not sure how much room under the steps as they are close to hull side. If you open them up post a few pics.
 
.......then to mid-cabin closet to 12V and antenna hook-up.

I guess that you are saying that you placed the antenna in the mid-berth closet? Did you buy one of those flat square looking things as an antenna?
Have you replaced the bayonet bulbs in your cabin light fixtures with LEDs? If so, can you give specifics on what you ordered and from whom? Also, can you give some specifics on the LED's that you used for step lighting?

The TV antenna is on top of my radar arch (see signature pic). The amp and splitter for antenna is in my mid-cabin, so I have a cable from TV to splitter and then two cables from splitter : one to Antenna and.... one to dock cable in.
I have not replaced cabin bayonet bulbs but would like to. Here is a link to my post about the LEDs I installed on steps:

Interior looks great - I'm having my cockpit seats redone this winter and if money is left in the boat fund the interior as well. Thanks for posting pics!

We did the banquette seats and backrests in a high end, teflon coated material from Kravet, Beth Page, NY. It is about $45 a yard. Banquette took 9 yards (we did not do the fill-in cushions for the sleeper since we never use them and never will).

The berth cushions and rails took 16 yards of a lower priced material ($15/yard). It came from Lewis & Sharon Textile Co., Atlanta.

We pulled all of the cushions and banquette seating/backrests and took them to our upholster. The labor charge was $850. (All of the pillows were extra)

I'm telling you this so that you can get an idea of cost to complete. I had one upholster come and give me a labor estimate. He came in at $1,750. Needless to say, we did not use him.

You are going to find the better materials (quality and selection) at fabric shops used by the trade (ie: interior designers). Just a suggestion, but, if you can find an interior designer that will give you recommendations on an hourly basis, it is well worth the money spent. A few hours of color/pattern consultation for selection will help you get the effect that you want.
