Thanks mate, that makes perfect sense and saves me a lot of brainache for nothing. Looking at the pictures closely it's now obvious to me, flat deck + V bottom = chamber = dry(ish) feet.

The early seariders did indeed have the foredeck spray cover - but not that shape and they also had a GRP moulding to support the rear of the spraydeck, steering and a windscreen.

I reckon the tubes may be from a 4m Avon SIB as suggested.

From a SIB like this one perhaps?

I'm thinking you may be right, so is this a bad thing? Am I right in thinking that this may be an SR4 hull with Avon SIB tubes fitted to the top? If it's a pro job or at least a solid quality pairing, will it make any difference to the performance and handling do you think? It's certainly near impossible for me to tell the difference but I'm hardly a beginner yet even, nowhere close to veteran.

If they've been fitted well - and were a reasonably good match shape prior to fitting, given what you paid I wouldn't be too worried.

Do they look well attached?

Firstly hello & welcome to Ribnet!

I also when first looking at the first pic thought "W400" or "S400", but the pic of the transom Looks a lot like an SR4! I think you might have hit the nail on the head there.

I used to own an SR4, and 25HP will push that along at 20 knts easily

Also forgot to say - the flooding hull is a good feature for fishing - when you stop you get a stable platform that doesn't get blown sidweways at wind speed!

It does however mean you get a wee bit of "entetrtainment" when you start, as a bigger engine will lift the whole lot onto the plane easily, whereas the 25 leaves you at 45 degrees (not really, but it feels like it!) for what seems like forever (call it 15-20 seconds!) before the water drains out and you are up on the plane.

Simple solution - store fuel / anchor at the bow, and if you have crew - get them to move forward on take- off - simples!
