Mmmmm, weight distribution is critical on this craft. I always found the largest, most over-weight person I could find and stuck them in the front console seat. The difference in performance was remarkable. Try to keep most of the weight as close to amidship as you can get. Utlimately your problem is (as you have identified) too much weight on the transom. You require more stern lift hence my suggestions via e-mail.

Food for Thought

I am currently looking at chart plotters and was rather put off for what you got for your money.

When the new boat arrives I plan to fit a decent plotter. The Garmin 176 I have is OK but the mono screen is far to small. It uses Blue chat which I run from CD which i find great. it comes with its own PC based plotter which you use to plan routes etc and download to the Garmin on a PC. If you connect the Garmin to this plotter it gives you a full blown plotter on your PC.

This got me thinking pound for pound what would you pay for a 10" colouer VGA plotter, say 2K is about right.
Having the GPS and the plotter software I got thinking about PC's on RIB's, why not.
I have looked at micro PC's 105x120x40mm, 12 volt powered and laptops fitted with a external sealed LCD screen.
This gives you full PC plotter on a 14" SVGA bright screen for about 800-900 quid !!. If you go for a smaller screen the cost drops a bit but not much. Plus there is lots of other PC based software which you can then make use of.


I am putting the final bits and bobs toghther but should have all items in the next few weeks. Once the new RIB arrives its just a matter of fitting the PC into the console (in a water proof box) and the screen to the console. I also plan to fit a waterprrof touch pad (like on laptops) so you have full control.

Go on call me mad, but I think its the way to go, I will try to get some pics once I have thing toghther but am now thinking that 2K for a plotter, who will pay that.

Regards Gary

The PC sounds a great idea but the hard disk will not last past the first good wave. The idea might work if you can find some way of using something that has no disk. you could try an Ipaq and use an external screen the same as for the PC.

Hope it all works

I went throught all of this last year when looking for Electronics for Topaz. I went to the London Boat Show and tried out the various models. In the end I chse the Garmin 182 Chartplotter in mono - I decided against the colour version on the advice of Garmin themselves, who said that on a RIB there would be an issue wth visibility in sunlight, and fitting a cover made the unit very flimsy.

Other makes I looked at were also good, but many were just too big and cumbersome, or too delicate for a RIB.

As for using Garmin's own technology, the Blue Charts are excellent, and if you choose the CD and Blank Cartridge option this becomes even more cost effective. As for longevity, they are still updating their old map system, and claim that they will do so for a minimum of 10 years. Should BlueChart be superceded (and it is an almost brand new system) I am sure they will offer the same service.

The one thing I have found with Garmin is that their chartsare made for their systems, and work perfectly, wheras other makes buy in chart technology, and I have seen some incompatibility problems. Also Garmin's customer service is excellent - they have always answered my queries, and sent out information on request.

If the Garmin is as good a price as you seem to indicate, I would go for it.

Thanks Graham, I have no qualms about Garmin products as I have virtually gone through their entire range including your current model. Its just that having used Raymarine on my Targa as well as navigating with Hot Lemon's 10inch plotter, I sort of fell in love with these units. I spent a number of hours with a friend of mine yesterday who is the local agent for Raymarine and he gave me impartial advice and a good demo on a number of the plotters. Raymarine vs Garmin is probably a little unfair as they are both exceptional units, in this case the price of the Garmin 2006 (colour) is at a rock-bottom price and the Raymarine dealer will offer his plotter at a very competitive price. What to do, what to do??

I think everyone on this forum will have different opinions, ultimataly its a balance between reliability, cost, user-friendliness (is there such a word?) and size. I will let you all know what I decide.

With the choice narrowed down to Garmin vs Raymarine, then you're not going to go badly wrong either way!

Garygee, don't even consider fitting a PC to a RIB unless it is a fully ruggedised version, something like this. You need to be looking at military spec kit if you want to have any chance of it lasting, and they don't come cheap.

Really, really, don't spend hundreds of pounds on a regular mini PC for your RIB. Put it in your car instead, where it's more likely to survive. It would be good to have a combined chart plotter and MP3 player though

PC In a RIB

Garygee

I have to agree with John. I work in the iT industry and the hard drive and the cd rom drive would not take the pounding that a rib gets. I cant imagine it lasting very long. Military spec lap tops are mega expensive too. Stick to a normal chart plotter.

Charles, My Raymarine 425 being the budget end of the Raymarine range cannot be interfaced with radar etc - doesn't have the seatalk bus. Its a good bit of kit for its price though and I like the Navionics charts.

I've used the Raymarine kit on Cyanide extensively as you know and have been very impressed with it right up until it all going on the fritz in Scotland this year!

I have just spent a day driving a Ribtec 6.45 with twin 50 Hp Merc 4 strokes. The boat was safe but not very exciting, topping 27 knots with a light fuel load and one person. Fuel consumption for both engines was 35 lph at full speed. I appreciate your hull is different and potentially has some real advantages but I am glad I didn't buy the rib with twin 4 stokes. Go for the big single with the big thrills

Hi everyone

Its interesting that yet again its down to Raymarine and Garmin and I would say while they are both very nice i think they are over priced.

I think I am still going to try the PC route, i understand your comments about the hard drive etc and was not planning to use one !. I work within the embeded PC industry as a designer.
The route I was planning to use a industrial embedded PC as you dont really need all the power desktops give you, they are small and are low power. The hard drive would not be present being replaced with a flash disk, while this will be slow to boot with enough RAM it should not slow the system down when running.
The entire pc will be in a IP67 enclosure and inside the console.
The LCD I am looking at it a standard vga panel, no case. This will be mounted into a case again to IP68.

I hope this should do things, I can get much of the stuff very cheap through work so if things dont work I can play a bit to get thing right.

Anyway I will let you know how things go as I wont be starting this until my new RIB arrives early next year.

Regards Gary
