Some do, some don't. It's horses for courses really.
The boats I've helmed that have them don't feel as 'planted' at large throttle openings as a full length V, but they've tended to be rather quick.

one reason why the RNLI have them on the atlantics is that it also gives less draught at shallow depths and that when beaching it keeps the boat stood upright for ease of recovery .

Planing pad on Eco XR24

We have a long pad on the rear of the hull of the Eco XR24. It's mainly to reduce the draft aft, but it also helps with dynamic stability. It increases the lift aft and has a similar effect to moving the cg forwards - preventing porpoising at higher speeds. It also helps the hull to get onto the plane more quickly. You can just see it in the CAD images on our website: http://www.eco-marine.co.uk

RIBase
Their is a plaining pad on My valiant Dr 490. I feel that this can lead to a solid landing if the boat leaves the water. I am expermenting at the moment by placing ballast to the front of the boat to move the center of bouyancy forward and away from the plaing pad. I have not been out enough to make a final decision if this has worked. My concern is that in a following sea that I may have too much weight in the front of the boat.

I feel that the boat would handle better if the pad was not in place.

I am looking to achive a comfortable 20kn in a head sea. I can achieve 18kn but it tends to get uncomfortable at 20 kn. Am I looking for too much speed and comfort from sush a short hull ??

Can you tell by the way the vessel moves that it is of any advantage.?
