Motomar Floating 430

I'm in possession of a Motomar Floating 430 RIB which has been shamefully neglected over the past few years. It seems a bored dog can make short work of a covering tarp and can do some serious damage to the rub strakes! So I will spend some time this spring fixing this little boat up as best I can and welcome whatever advice you good people see fit to offer.

There don't seem to be many of these stateside. This one made its way to Valdez, Alaska, to help with cleaning up the oil spill in 1989.

Here's what it looks like today:



The hypalon tubes appear to be in good shape. Given the amount of damage to the strakes I plan on removing them and replacing with new. Or, if I can find a matching style I may attempt to cut off and replace the damaged portion and reglue the remainder. Most likely will be complete replacement.

Here's a rear view of the transom:



I'm thinking I should replace the plywood mounting plate.

It has 4 chambers, and I have yet to inflate any of them to see where there might be leaks or if the baffles are intact. Here's a pic of the valves:



I know not what surprises await on the underside!

Here's what I have laid out as my plan for rescuing this poor neglected RIB:

1) Get it in my driveway where I can work on it. Clean it up properly and inflate. Locate all leaks and assess feasibility of repair.

2) Repair or replace the rub strakes.

3) Consider replacing the valves. I'd like to have a standard valve that can be easily maintained, such as the C7.

4) Repair where the tube attaches to the transom. The entire attachment to the hull may need re-gluing.

5) Repair the transom as needed.

6) If necessary, completely remove the tubes. This will allow easier access to repair the tubes as well as enable proper cleaning and prep for re-gluing. Painting the hull would be possible at this point too. Of course this would come before step 4.

I've done none of this sort of work before, but I'm not shy about taking on complex DIY project. I am completely new to the jargon of the RIB community despite having owned this boat for 15 years.

This is very promising

I filled the tubes this morning. Took this picture about three hours later.



We got our first taste of warm sunshine today. It's been a long time coming. Tubes got pretty hard, enough so that I opted to bleed off some pressure. I need to get a pressure gauge so I'm not left guessing how much air is in the tubes. Now in early evening the tubes are cooling and starting to sag. Hopefully it's just contraction and I haven't lost any air. Even still, no major leaks in the tubes and the baffles appear to be intact.

The next step is to turn it over and see how well the apron is holding to the hull. Is that the right term, apron? It seems appropriate.

Looks pretty good. This forum has seen much worse.

Keep us posted on the progress!

Hope springs eternal

I spent some time scrubbing the tubes using mild dish soap and a soft scrubber. It looks pretty good, at least from a distance. The aft starboard tube still needs some scrubbing. All the snow has melted but that corner of the yard is a squishy mess.



The lichen that was growing on the tubes has left some stains on the orange wear patches. This picture may not show it unless you click to get the zoomed in image.



What's a good product for getting hypalon sparkling clean? I've got plenty of elbow grease and scrubbing pads, but I'd like to use something with a bit more cleansing power than dish soap. Any suggestions?

I think I've found an answer to my question and will be getting some 303 cleaner and protectant.

CT - the NAF (North American Forum) guys will be able to advise you better about cleaning products than I can (in Ireland) but quite a lot of mildly alkaline domestic cleaning products work well, especially if you work them over with a slightly abrasive Scotch pad. 303 protectant is good against sun damage, there are lots of finishing products that restore colour and gloss - while they stick...

Tube pressure - for use, the tubes should be hard and should bounce a punched fist. As you know, beware strong sun if it doesn't have overpressure relief valves.

Nice find, BTW. I'm guessing you got a bargain?

It's amazing the difference it makes just pumping the tubes up and giving something a quick scrub.

No great bargain as this abuse is all self-inflicted. I've had this boat for nigh 15 years. I don't really want to do the math because that would probably indicate I am as old as I'm starting to feel. I have a slow leak on the port tube, I suspect the valve. Locating and fixing that is my next to-do item. Thanks for the NAF suggestion, I'll check it out.
