40hp Enough for Skiing?

Anyone got any thoughts on a 40hp being enough to pull up a skier on combo skis? Its a Honda 4 Stroke on a 4.2 Rib.

Want to get some ski's having tried it and now being addicted to it, but dont want to waste money if the engine / boat wont cope.

I had a 4m commercial searider with a 40hp mercury - it did struggle a little to pull up a big lad on two skis BUT amazingly if he dropped one ski once up it could provide a really good monoskiing expereince, one of the best he had experienced apparently - lovely wake pattern. It's all about weight distribution and I would recommend a longer than usual bridle which seems to lower the centre of the line. Only problem is remembering where the other ski is but a few inches of orange dayglo paint on the tip of the drop ski and a small piece of lead to induce a "tip up" floating position and we never lost it!!!!

With the same power, an SR4 will take longer to plane than a 4.2 Zodiac due to the deeper vee hull and flooding chamber which bogs the boat down.

we used to ski with a 3 cylinder volvo-penta 35hp o/b on a heavy 5m Morebas hard boat and it managed everyone thru their learning stages except for a particularly corpulent mate-but we did a lot of dragging him around in a sort of attempted drowning/colonic irrigation mode. Good entertainment for the boat crew.
After that a 40hp 2 stroke Mariner was a vast improvement, and then a 50 Yam. So you should be ok....except that Honda o/bs are not noted for their get up and go, they tend to be the engines that you go and check the hp number on the hood cos its seems to be missing some hosses! You may need to shove the observer up into the bow to aid getting onto the plane.

My Avon Adventure 4.0 with a 40 Yamaha 4 Stroke could pull skiers up easily and drag a couple of ringos as well (Not at the same time!). So you should be fine.

That brings back memories of getting towed behind an small Avon R.I.B with a 15hp on the back. It wasn't much fun getting up, but it could be done!
