I assume they are suggesting this as using a trim tab all the time to counteract torque effect will cause extra drag?

Absolutely minimal. It just needs to be skiffing on the water. When using my tabs for counteracting listing, I notice no change of speed.

I'd listen to Scorpion, they'll know their boats best.

You can come out with us and see for your self.

If Scorpion say you need it then you do!. They know an awful lot more about building and rigging Scorpions than anybody else on this forum.

Call me old fashioned but I dont think think they are gonna fkk up their enviable reputation by rigging a boat wrong.

One thing I will say about tabs. Remember to lift them when you moore up. Last season I forgot to do this on a number of occasions. One notable time was after using one tab, well down, in a beam sea. We stopped in a harbour for lunch and afterwards we left at its side entrance, turned along the harbour wall, opened the throttle and met the sea side on with the wrong side tab well down. That wakes you up. They don't half seem slow to move when you need them in a rush!

I've bought an auto tab retractor but it's not yet fitted so can't comment on performance.

Quick / slow?

What tabs are they fitting? They normally fit twin ram Bennett tabs. These are painfully slow.

Some manufacturers (cruisers mainly) are fitting Lenco tabs. These are quick acting and the standard switch panel has built in position indicators. Not sure how robust they are though.

Thanks Roy for your kind offer!

The hull does actually have trim tabs attached (Bennett). I had these on my last boat (only single rams) and they made a significant difference, especially in cross winds or just to counter-balance excessive weight on one side. The new boat will have dual cylinders so may be slower to respond but should be considerably more robust.

On this basis, I should think that a limited list to starboard plus use of trim tabs, as required, should be a good compromise - and keep the tubes out of the water, while in the marina.

Regards,

Chris.
