Bunk replacement for 430 Inflatable

[Danncus]

Hi. The bunks on my trailer are past their best and need replacing. The boat in question is a quicksliver hd 430 with 30hp tohatsu. I'm used to grp hulls, and I find the boat/bunk very sticky and not easy to launch /recover without completely floating. so my question is
What will work best on an inflatable hull?
The bunks are covered with some sort of Lino. I was thinking of treated decking, or possibly decking with UPVC strips on the contact surface?

Thanks

Plastic decking is used for bunks pretty often (the 2x4 or 2x6 synthetic lumber - usually HDPE.) Be aware that the stuff is less rigid than lumber - you may need to increase dimensions or add bunk support if you go this route.

As you said, the HDPE screw-on pads will work as well, but will also concentrate the force as they're usually narrower than the bunks.

On my SIB, I actually preferred having to float the boat off - it was less concerning than dragging the boat across the bunks. Had to go a little deeper, but the trailer was getting wet anyway, so...

Look at direct plastics 2000 x 500 x 30 MM HDPE around £100 cut into 3 lengths very low drag coifficent round corners off with a wood smoothing plane. Or look at tyrone trailers they do a roller set for RNLI beach rescue craft might be what you want.

You can buy a spray too for carpet bunks

thanks for input i think the HDPE is too expensive for me though. I agree floating is probably the way to go. in which case would the timber decking be ok?

you could use a thin HDPE on top of wood bunks[tanalised timber] from B&Q thin HDPE not expensive have a look on direct plastics

Probably what was in place to begin with. Get a good rot resistant type of wood; clear cedar is great if you can get it. Also good to treat it with something like a deck sealer prior to installation.

You can cover the lumber with outdoor carpeting. Make sure you use Monel or stainless steel staples to attach it.
