Ribcraft 585 Floor Thickness

Hi everyone

Possibly a strange request , but ... Can anyone tell me how thick the floor is on a Ribcraft 585 ... and is it a honeycomb or a solid panel ?

cheers

Ian

Its solid glassed ply. Not sure on the exact thickness. Try dropping Dorian a PM

Thanks for the quick reply PD

I am going to fit some girly toe straps to the boat and was looking to "pot" some threaded inserts into the floor ... I dont know why i assumed it was a honeycomb structure ... just seemed logical and strong to me as an aircraft engineer .....

It seems that wont be necessary though .... Just some good old heavy duty SS self tappers needed

cheers

Ian

Thanks for all the replies guys , much appreciated .

I am kinda separated , temporarily i hope , from my boat by a couple of hundred miles at the moment ... hence the question ... I am just trying to prepare a few little tasks for when we are reunited :-)

Again , thanks a lot everyone .... I'll get some 1" screws ordered asap.

cheers

Ian

I owned a 585 for about 15 years . It came with footstraps glued down ( almost certainly from new ) . They never looked like loosening , even after some very lively trips with heavy folk on board . So do you really need to drill at all ?

That's a question I always ask myself.

And would say to only drill or put a screw in the deck if you can be completely sure of your ability to ensure no moisture will find it's way down the side of the screw and into the ply.

Once that rot starts it's the beginning of some big surgery for you.
Remember also to ensure the screws don't break through the underside of the deck so moisture can't get in that way.

if you do screw coat with gorilla glue its 100% waterproof and swells 4 times needs the hole to be moist to activate the glue

I've not used Gorilla glue but I guess in the same vein I tend to dribble a bit of epoxy into the hole if its a blind hole and I give the screw a wipe with a bit of acetone to get rid of any grease / dirt.

The moist hole comment causes me some puerile sniggering.

As BH has had good experience of just gluing, then that might be the route to go down first.

But as previously mentioned it needs to be a tight but moist hole.

Gorilla glue is brilliant but wouldnt use it for this purpose.

Drill and either use epoxy or sika/5200 is what we have always done.

The deck on my boys 6.8 ribcraft is 3/4 ply with laminate top and bottom but to date he will not screw anything into the deck. He wont even upgrade his transducer to avoid drilling holes in the transom.

When he was getting suspension seats fitted he did consider bolting in but in end went down the glass route to again avoid holes in deck.

you can also use swellseal mastic sets in the dry and wet and creates a solid construction joint

I always just make sure there is a seal of Sikaflex or similar on the bottom of what I'm putting down and also smear the screw with the stuff.

Thanks guys

My footstraps are going to be homemade using x2 2" long SS top hat brackets for each foot and some 2" webbing stitched into loops ... so i think i will be going with the SS self tappers and sikaflex in the holes and and a nice bead around edges ... that should keep any moisture out for many years .

Although car has just started developing a drivetrain whine .... so i think i might have to put getting it down here on hold till i can get out and get it fixed :-(

or get boat delivered ......

stay safe guys

Ian

I would encourage you to glue them rather than screw them in.

These are the RC factory supplied ones and they have been glued.

Be warned though they are forever getting in the way!

Hi Chris

Thanks for the reply and the pic ... up till now ive been pretty definite that i was going to screw them down ... I have bought my brackets and webbing .... Though maybe you are right .... I have a bit of an idea about how i could glue them with a 5 or 6 inch long top hat to cover the webbing .
I'll keep ya posted .

cheers , Ian
