boat modding

[mzaakir]

Hi guys, so I am purchasing a 4.2m tinny and its all in relatively good condition but super basic and not comfortable for my fishing style. Planning on doing a deck and making a casting deck but don't know what would to use? Dont want something super expensive but dont want something cheap. Planning to put marine carpet or some boat mat over it, any suggestions for that is appreciated as well. Also what hp motor should i put on it?

Thanks in advance

sounds like a good buy, for flooring i used marine ply 9mm and put some marine varnish on to top it off. depending on the builders plate you should go at least a 30hp up to a 50

Form ply is a cheaper option - you just need to be fanatical when you seal it with paint. Use a bit of grease in screw holes.

I'd recommend a 4 stroke motor for the better range they give you. Go the max rated HP for the boat.

I had a fibreglass boat builder laugh at me once when I quizzed him about marine ply. He said "There's just ply, the marine part is hyped and what really matters is how you seal it....". I'm sure there are different glues used etc etc... But sealing is paramount apparently.

@ellicat is right form ply is cheaper. It's the sealing process which gives longevity of service. Particularly with carpet over the top of it.

thanks guys

I went through the same years ago. Timber flooring & marine carpet.

Motor not less than 30hp. 4 stroke is the go.

Most important check for Electrolysis.

Cheers.

ok thanks, still researching about wiring and everything, confusing the crap out of me

Just went through this replacing the floor of my 4.3m runabout. Spoke to a guy from "Plywood and Panel" here in Brisbane (guess what they specialise in?) and asked about marine ply. Apparently they used to supply ply to Quintrex and he recommended regular old structural ply with"marine bonding" (means the glue's not water based) and 2-3 coats of water based acrylic paint on all surfaces to seal it (apparently oil based paint messes with the glue). Important thing to remember is to drill/cut all the holes (including screw holes) notches etc before painting, as the edges are the most important part to seal up. I then covered it with marine carpet from Bunnings, glued down with artificial turf glue (which is designed for outdoor use and amusingly is bright green) and stapled on the rear with stainless steel staples. You can get the staples from Whitworths in Brisbane (and probably many other chandlers), and Kennards have an electric upholstery staple gun that fires them (they don't fit in regular old manual staple guns). The other thing to note is that you'll need to screw it down to the boat, and that stainless steel screws in aluminium will cause galvanic corrosion. The solution is to drill the holes in the ply large enough for the screw to pass through, drill the holes in the aluminium to suit the self tapping screws, and coat the screw threads with tefgel or duralac before you screw them in. (Duralac's toxic, use rubber gloves... or just use tefgel).
