best lower helm electronics?

Hi all,I am thinking instead of installing a fixed GPS unit that perhaps I can just run a laptop GPS from the lower helm. *I've got an old PC laptop that we don't use anymore so I can set it up there as a dedicated machine and hopefully figure out how to network it up to the flybridge via a large screen display. *What's the most cost effective solution/set up that most folks are running? *Right now we're on an inland lake so I am not needing to be able to cross the seven seas, well, at least not yet! *

RE: best lower helm electronics?

Hi woodsong

I use a net book (just a smaller version of a laptop) at the lower helm station
It has a usb gps receiver
OpenCPN nav software (it is a great and very easy to use program free on the internet)
C- map CM93 2010 charts (you can also download this program on the internet)

It all works a treat and I see no reason why you couldn't send it topside. Although computer monitors are not real good in sunlight. There might be a suitable one out there though.

I have an old Dell notebook that I use. Check out Coastal Explorer (Rosepoint Navigation). I bought their program and their gps receiver and really like it. GPS plugs into the USB port. You can download NOAA charts for free.

FF: Most modern Laptops will work fine, as long as they have a USB port and Windows 98 or later.

We use an ancient Gateway Solo Pentium 2. It's at least 9 years old. The screen is broken so we have a separate 15" monitor. OS is windows XP Home.

It's below spec for the software - Fugawi with Navionics Gold charts - but works just fine if a little slow sometimes. The GPS is a USB plug-in called Deluo. Bought it 6 years ago - don't know if they're still available.

RE: best lower helm electronics?

Allan,
That is the same USB receiver (BU-353) I found online today and have been leaning towards. Now i just have to settle on what software to get that has the inland waterways (TN River and Lake Lanier, GA which is where the boat currently is at).

Try open CPN

http://opencpn.org/download

and see how it goes

You can try your local charts with it

Also if you can get a copy of C map CM93 2010 version it has a lot of inland lakes also but not sure if it has the one you are on

RE: best lower helm electronics?

Allan,
I have one of those little USB GPS units that I got off E-Bay. I think it only cost me 30 odd buck
GPS USB Dongle ND-100.
I am sitting here on the Mermaid Vantage with the GPS taped to my port light and it picks up at least 12 sats.

This way I can keep my eye on those bastards on the mantlepiece (bridge) , make sure we are going in the right direction.

RE: best lower helm electronics?

Me too. Hey Lurker, how's it going project wise? I've decided to bite the bullet, and Lotus comes out and goes in for anti-foul, prop-speed and a hull re-spray in a couple of weeks. Topsides need doing as well, but I'll do that. I think a quote of $Aus7,400 not bad for that. Plus $1500 for anti-foul, of course. What's your next thing to do? Oh yeah, word or warning. That canopy extension - still think it's the best thing we did so far, but be warned - makes a lot of nice perches in under there for birds - still working on that.....ideas anyone?

RE: best lower helm electronics?

Peter:

I'm in a bit of a quandary about my boat. Do I pour $ into it to get her in the shape I'd like?* That would be lots of $ to tear out and redo the decks and house leak damage.* Do I do the work myself (like I have any time for that) or write the check? Do I just live with the damage and ride this baby 'till she drops of old age and exhaustion and then look for another boat?* Try to sell this one and get another in better condition?* I was fully aware of the condition of the boat when I bought it; I figured for the price I paid I could get a number of years of fun out of it. That's working as planned.* But, what now?

Decisions, decisions!* Currently I'm just maintaining mechanical and safety items.* Toys and trinkets come off e-Bay at low cost - SL555 windless, Autohelm, and now the GPS USB gizmo for the lower helm, etc.

Leaky decks will continue the rot , till the structure is mush.

IF you can stop the rain thru the decks , the rot will stop and you can enjoy a decade or two "as is".

How is the question,

Spray on/roll on truck bed liner is the answer I think.* But, even if I stop the leaks won't the soggy core just continue to molder away?

You could seal the damp core away where it can do no harm. Cheaper by far than a complete rip-out and re-core. Strip up the old teak - seal below with resin - bed in a thick layer of marine ply, then fibreglass over with several layers of cloth, finished with non-skid, and you get a good result. No more leaks. That's what the PO of my boat had done, and I must say the damp old core is just that - there but not at all evident, and that's after 10 yrs, so I think it's safe to say dead & buried for good. After all it's got fibreglass either side of it, then reinforced deck over that again. I then got stuck in and replaced/covered any leakstained/damaged interior finish, and we have ended up with an interior comparable with new...well almost.... but she's ready after this hull re-spray, to go for another 35 yrs.
Watch for the new avatar pic minus yellow bow stain....

RE: best lower helm electronics?

Peter:

Well, I will have to say that is food for thought.* The layer of marine ply and cloth should deal with the soft spots in the decks.* And that method will certainly seal things up.* It sounds like something I could deal with in stages and not lose an entire season or two of boating.

How was the core damage in the house handled?* I'm assuming that treating the flybridge the same as the main decks and addressing/upgrading the windows will stop further water intrusion into the house core.* Then deal with it from the interior as, and if, necessary?

I've read about a zillion posts on how people have addressed these issues.* But I don't recall anyone with 10 years of living with the soggy core just encapsulated and forgotten about.* I like the approach.

RE: best lower helm electronics?

Burying rotten plywood and glass with yet another heavy layer of plywood and glass is still not a "fix".


Remove the teak, and lay down a layer of glass set in epoxy and lay in a core of marine foam.

Airex is great but expensive , nadia core or other brands are way cheaper.

Then glass over the new core ,

voila a deck that is light insulated and probably 400% stronger than the origional ply mess, that will not be requiring yet another layer as the ply rots.
