I have a 't' board on my Lodestar. I guess it does the same job. Never had an issue with it. It's laminated/grp. What's your made of?

hi, not sure as it came with boat (which i have had since new, 10 months ago) but it looks like some sort of ply with a pvc coat on it, it has broken twice and both times was in small choppy seas...

maybe invest in having a pukka one made? Also....be careful not to over inflate the keel?

Sorry guys and gals,could anyone explain what this thrustboard is and its function i have a 2.7m ranger with high pressure floor and keel but no thrustboard,i am new to this so dont no much

it was there originally to spread or terminate the power from the engine along the boat via the wooden floor ,in theory the engine when powering forwards is trying to rotate or twist the transom and the thrust board was there to stop the floor from moving forwards thrust boards are placed at the bow where the tubes start to bow in so as to give some thing to push on to .

As far as I can tell this board is there to keep the airdeck in place and to keep the keel from moving upwards (see attached diagram). My SIB, a Quicksilver 340, has taken a lot of stick over the past 8 years and I've never had a problem with the thrust board. Perhaps the problem is that you are not inflating the keel and the airdeck enough and there is flexing occurring.

You could easily make a new board from marine ply finished with a good varnish or marine paint. MUCH cheaper than a new one from the manufacturer. My pal Charlie made me another seat a few years ago and fashioned the plastic clips from an old plastic drain pipe - it has been perfect for the job and was a fraction of the price of a QS one.

The board on my 2.7 is heading the same way. Too much fun I reckon

I'll be making one come the time. Maybe I should do it now...!
