Blocking off the hull (SR4)

is there a simple, cheap and non committal way of doing this.

I fancy giving mine a go, just to see how much difference it makes.?

Any links to websites much appreciated.



James

I filled my front with plastic padding and gelcoat filler worked well and has lasted a few years no problem

That looks a bit permanent..!! Or would you just dig it out when you wanted to return to original set up.?

What about the larger hole at the stern.?

And the back I blancked off and fitted a drainer plug, it has stayed dry for over 3 years I put a Perspex plat in so I could see if any water got in, but it has not to date

Why not the best of both worlds? Put a valve in, as they make a marine version that many wakeboard boats today use to flood their hulls. Otherwise they are commonly use in camping cars aka motorhomes, to drain the waste tanks. There are even electronic versions.

I could just put a drill through it and dig out the rest if wanted, don't think it made too much difference but I wanted to make it lighter when it drys out on the beach or morring. I was wored about the extra weight and the deeper draft, I can push it back in the water if it dose get left high and dry

It is a gate valve commonly used on RV's to drain the sewage. They were adapted for boat use on flooding hull boats to allow one to choose when they want to fill and not fill their hulls. They can also hold the water in the hull to create a bigger wake for wakeboarding and surfing behind the boat.

With a 3" diameter and remote operation it would be ideal for an SR4, and what I would install if I owned a flooding hull RIB.
