I didn't have trim tabs on Blue Ice & Richard B hasn't fitted them either since he's had her. (7.5m Scorp). I can't say that I ever found any real problem with leaning into the wind that couldn't be corrected by trimming in or out or rearranging the crew seating. The 7.5M Scorp works well trimmed quite a way out out in most sea states, particularly when going 'downhill' in a following sea. She does need trimming in when punching into a head sea like most boats.

30ktsish is a good most sea state cruising speed. Any slower and she doesn't 'fly' so well. She will go a lot faster capably but 30-35kts feels like a comfortable cruising speed you can keep up for an extended period without banging the crap out of yourself and spending a fortune on fuel.

As with any boat, time and experience will enable you to get the most out of her. Beam seas or large washes are uncomfortable, perhaps because the tubes are a long way out of the water compared to other ribs. (my previous rib was a BWM DS21 where the tubes are still kissing the water when on the plane. Stable, but not so efficient!) A Scorp is a world of difference from a DS21 believe me!

Slow speed handling should be as good as any other similarly sized RIB. Certainly more susceptable to being blown around than a hard boat. Particularly if its an older model with the more bulbous bow toobs!

Anyway, I had the good fortune to relive the glory days on the solent recently during a flying visit. Happy days!

Having driven Blue Ice across the Solent to Cowes from Lymington last year (during Ribex), I found that it does "nod" quite a bit - is this usual with this hull or was it because I had her "trimmed for speed?" I have noticed it in Richards videos quite a bit as well, so I know it isn't just me!

Agreed! and im sure quite a justifiable reason to most people. IMHO The deeper the v or more warped the shape of the hull the more angle they have to lean onto(such as a scorpion) a dory dont lean much does it?!?. I found in general it could be steered out but tabs seem a almost standard thing on scorps with one particular bennett model even being aliased "the jelley tab". I presume in some instances especially the i/b boats it could be to help with planning times.

It was impossible to move the crew around in this circumstnace as there was none and im not sure who would have driven if i sat in the aft seat.

Looking back on it i think the sideways lean was accentuated in my mind for me as im not used to the whole open boat scenario and really dont like high set jockey seats...

Cheers

I've noticed it several times. I think it's just part of the Scorpion's hull characteristics!

Technically they're probably the same thing but to different degrees.

"Porpoising" is usually used to describe a problem, but the Scorpion "nodding" doesn't appear to be significant enough to bother anyone.

When I purchased my Scorpion the tabs were allready fitted. It took me a while to get used to the boat, the motor trim and the tabs.
Now, after allmost three years, I use the tabs all the time. She drives beautifully in all types of waters.
"Nodding" occurs at times and I easily get rid of it by using the trimtabs.
At slow speed, say 10 km/hr, I put the tabs all the way down and she goes in one straight line. Even with no hands on the stearing wheel.

Scorpion trim tabs

I have a 7.5 metre Scorpion and I use the tabs all the time to ensure the boat is upright and we also have a single engine. For trim we move the motor. Oddly, I find the slow speed handling better than I had expected. I find the long and relatively narrow hull steers quite well at slow speeds - even when gliding along with the engine in neutral. I personally wouldn't consider one without trim tabs as I think all narrow ribs will heel one way or another due to engine torque, passenger weight or a crosswind. Gavin

Why do some of you persist in referring to these boats as "Scorps"?

The correct name is Scorpion.

I don't see other Ribs being called Avs, Sols, Osps, Parks, Zods or Bananas.
