Have a look at these for a comparison-both were taken from a 5.4 Searider at full throttle with a handheld camera-of 2 Seariders at full throttle. It was flat calm in one-which is me solo, and a bit bumpy in the 2nd, which is Doggypadddle from here solo.

I took the boat out today for the first time and was pleasantly surprised with how quick it got to plane but it was very twitchy at 30+ .
It felt like it was perched on a peak and was just waiting to fall off , A couple of times I had to pull the throttle back sharply or it felt like I was going to flip over sideways.
Is this normal with deep v hulled ribs, I have never had this with my little caribe rib and I am often flying around at 35+ with no problems.

All help welcome
Hi there,
a friend of mine had the same problem with his phantom powerboat (not rib) he retro fitted the Hydro planes that you can buy relativley inexpensive to the cavitation plate on the leg and this sorted out the problem straight away.if youve had planing hulls before i imagine that you will know about over trimming the boat and its effects.
Hope this helps.

When carrying the weights and anchors up front she never used to be a problem. Move the fuel forward, trim with engine height, add some extra chain, carry a 24l spare.

Doesn't really matter, the key thing is you need to balance the boat against teh weight caused by having the operator further back and a big lump. It's not teh boat, just the way she is now being used.

Moving the console forward would also work, but I'd be trying balance weights first as it's easier and less effort.

I would agree that looking at your last picture of engine and transom, it might be one hole too low.

Console looks a bit far aft if the footprint was the original console, engine could do with being raised. The big one is the closure of the flooding hull, this could be full or half full of water. Still a hole to see and fit a bung. You could have too much weight aft. Engine weight may not be terrible as people fit twin 40 two strokes to these which would be around 160kg.

Yep, good advice too

Also if those are holes in the transome, they need to be dried and filled.

I'm about this week near J16 of the M4 if you need any help, I also have the correct gelcoat pigment for your rib

I should be out on the water later in the week if you can make it down to the solent, maybe friday?

Jock did say it had twins on before.
I plan to move the steering console forward to where it was before then I can fit the rear seating console as well.

I want to get the outboard off and clean up the transom ( it has more holes than a culander ) whilst off I will fill all holes and put a drain in, could do with a new elephant trunk just don't know where to get one.
