I think the OP is Panama City, Florida.

I have an aluminium 2.9m RIB and an aluminium 5.6m RIB. I also have a 4.7m fibreglass RIB and an 8.9m fibreglass RIB.

The aluminium ones seem stronger and lighter for their size. They are noisier when they hit chop making them sound not as robust, but they are pretty tough. They ding instead of crunch when you hit something very solid. Don't have to worry about rot with the aluminium. Yes the aluminium does eventually corrode but based on other boats I have had it probably outlives the fibreglass. The fibreglass usually looks better because of the shapes that can be formed and the colour.

Personally I think who built it and how they built it is more important than the material.

Many thanks for al the very interesting suggestions and comments. I have been considering aluminum since I wish to have the combination of strenght, and low weight for a 7-8mt size to facilitate shipping via sea container, trailering and lower fuel consumption. I am based in Ciudad de Panama (not Panama City) but I work in the humanitarian sector and often work in countries where there is little chance of sea rescue and wish to have the largets size /lightest weight I can get in the second hand market since I will definetly not be able to afford a new rescue type aluminum RIB.
I am not in a hurry and I will keep an eye open for aluminum but othewise I will definetly consider fibreglass.

Hi. As Dave says I have a 7m aluminium rib with a 140 tohatsu on the back

Any questions please feel free to ask happy to share my experience to date

Very happy with mine so far. Feels very solid etc. FYI my tubes are fitted by sliding them onto grooves. In theory they would come off for maintenance etc. I suspect reality is it would be a helluva job

I wouldn't avoid glass. Lot easier to come by, and, unless you're planning on a lot of boating in shallow rocky areas in water with a lot of movement, the strength won't come into play much.

The fuel hit from glass vs aluminum won't be a deal killer, IMO. If it was, more glass hulled boaters would be trying to run solo with no gear on board.

I went with aluminum primarily because I was spending a lot of time off rocky shores, often in pretty close. Of course, once I got the more capable boat, I've been spending more time further offshore. Go figure.

Hi Neil and Jyasaki, what type of aluminum boats do you have and any pics? I have just tought that another advantage of aluminum hulls could be that they may be safer and easier to rig for lightning shields?

The only "lighting shield" you'd possibly want to consider is a mast. As in a sailboat mast, well grounded to the sea. And you still don't want to be hit by lightning, it will fry every electronic thing on the boat and might kill you anyway. Highly unpredictable.

There's pictures of my 5m ali RIB in my gallery. If you are trying to ship this around the globe via container I don't think aluminum is going to save you anything vs GRP.

I am not sure but it looks like an aluminum RIB with an A frame connected with the consolle would provide some very good protection and dissipation of a lightning without any modifications in comparison to a standard GRP hull.... to avoid derailing of this Alu hulls conversation, I have started another thread regarding lightning shield on RIBS.
