I have dived the wrecked fishing boats about 10 years ago at Pulau Payer and would not really rate it as a great wreck dive, viz was awful and it was impossible to see anything more than a few meters.
There are a couple of wrecks around Redang, but if you are looking for some major sized lumps of steel, Palawan in Philippines might be a better option.
