Pedestal Seat In Plywood Floor

Ive got a 4.8m tiller steer open tinny. I bought two seats to put on the back bench seat.

Turns out I can only fit the drivers seat as the other interferes with the tiller.

Do you Think the 19mm ply floor handle the pedestal I’ve attached? 
 

Happy for suggestions. On getting a few more seats in the boat.

I reckon it would work. To make it less likely to pull the screws you could use bolts right through and use a washer on the underside.

That’s what I’m thinking Ellicat. I’ll give it a go & see how it goes.

Clean and neat looking rig by the way.

Thanks Ellicat,

I keep thinking of upgrading to a Quintrex 460 renegade, one day
But this one does the job for now. I do like the tiller steer as I can watch everyone in the boat & it has plenty of floor space. But long runs in the bay in the cold, makes me wish I had a different set up!

I put in a new switchboard earlier this year. Took advantage of it and made a mounting board out of HDPE plastic and relocated the ignition switch. Which has helped tidy it up. Need to neaten up the wiring As a few have fallen down.

If you wanted to make the rear seat more comfy for a passenger you can get lengths of foam that are made just for that purpose. I had one in the Force to save my kids' bony bums. Have a look on Whitworths site.

Actually @aussie123 's Reeltackle has them too.

Thanks for that. Will still put in one pedestal seat to try and save my Dads back when he come along. 
 

Along with  a cushion on the passenger side of the back bench seat will do the trick. 

On a side note, got the boat ready yesterday to take the family out. Was going to muck around on a few yabby banks in the passage. Didn't anticipate the rain! Another weekend without putting the boat in the water. 

[ellicat]

Yep, the wind or rain on the weekends often spoils plans. :(

Hey Towknee

The rig looks good, I think it will be a goer. I think the main thing would be having it screwed in really tight and sturdily. 

Like ellicat said also, that is a nice rig!  

Cheers Hamish

I'd probably go one step further and create a base plate out of some aluminium. Drill the holes in the base plate for the required positions , bolt the pedestal seat through and fasten the base plate on the underside with nuts and washers.

The metal plate will help spread the load across the plywood. The washers unless they are large diameter washers might still dig through plywood over time.

I’ve ordered a pedestal for a 2nd seat. 

this is the back bench set up. Will see how it goes driving the tiller in the seat tomorrow

I had a 20 ft Mustang a while ago which was ten plus years old. Was driving through a bit of rough stuff and the drivers seat suddenly gave way. Very scary and dangerous. Make sure any seating is well bolted down!

[Towknee]

@GregOug you are right.

turns out the cheap seat mount I bought from BCF, doesn’t use fasteners that suit boats. In particular nuts that vibrate loose. The days trip required the fishing pliers to keep the bolts tight. 

other than that. An absolute cracking day in the passage with the family.  

[bicter]

Use a bit of loctite on the threads for a simple fix, otherwise use nyloc nuts or shakeproof washers to prevent nuts loosening. Assume you're aware of the risks of electrolysis when bolting dissimilar metal together in a marine environment.

Hi Bicter, 

thanks for the advice. I would of thought the bolts would of come with lock nuts as standard. 

I guess you get what you pay for
