F-Rib Ride Position

[benhben]

Took my F-Rib 330 and Suzuki DF6 out on Coniston at the weekend. First part of the day was me alone, whilst my friend joined for the last couple of hours.

Both times I've used the boat, the ride position seems very nose up. With the DF6 I struggled to get on the plane at all, even with all my belongings stored up front. It was marginally better with my friend sat up front but still didnt plane with the 6hp.

With my Tohatsu 15hp it was even more nose up given the extra motor weight. Once it did plane, it flew.

The trim on both outboards both look ok.

I would have thought a FRib 330 with just me and a 6HP motor should plane ok. Are Fribs prone to Bow up travel or am I doing something wrong?

Hi, what pin trim hole did you have the outboard on?

[benhben]

It was in the closest hole to the transom. The shaft seems pretty much straight vertically when on the transom

The first hole was what I was going to suggest.
Presume fuel is at the front, your of average size and sat as far forward as you can until you are on the plane?

Not sure if anyone in the Frib world has the same 330 & 6hp combo to know how theirs performs. However in general with SIBs 6hp is a marginal motor to plane even one up. For example I've tried my 380 SIB with an 8hp and it did plane with a very light load but only just and it would fall off the plane easily.

My experience of flattish hulls (which realistically the Rib is) has been the wider a hull is compared to length the more potential there is for bow rise and the more power you throw at is the worse this can be. It's a case of powering through transition very quickly... if you linger the bow up attitude can be substantial and puts you off adding more power.

Edit: Of course Donny has a 6hp on his 275 Frib so he might offer an opinion... I think he gets on the plane OK all the time unless he adds anything above his standard/minimum weight. Have you noticed in his videos how far forward he sits... almost knees in the bow canopy? Where are you sitting?

Having owned an Frib your problem is lack of power to overcome the ‘hump’ to gain planning.
ALL the weight including yourself needs to be in the bow as Donny’s video demonstrated with his mates 6hp on a honwave 3.8 to plane.
I had a 360 with 20hp and planeing was instantly with the power.
Bow rise-max throttle- all weight forward.

This is true! I already have a Honwave T38, which given the extra space and deeper V I find more comfortable and more suitable to fishing from. it doesn't seem to suffer with the ride position as much as the F-Rib.

To be honest, the F-Rib was a bit of an impulse buy a year or so ago after looking at them for a while. Given the cost of living at the moment, I don't use either enough to justify having both.

Shame as I thought id get on with the F-Rib a lot better than I do.
