Paravanes on a Sailboat

[ViribusUnitis]

It has been long commented that a monohull vessel tends to roll badly when running wing to wing downwind.

What of putting something similar to a paravane on a monohull sailing vessel?

I havn't seen it done, but it seems like such a no-brainer to me there must be a reason not to do it.

Para vanes could be used, however they require to be boomed out, the ends of the boom also requires stays forward and downward. They exert a lot of force to counter the roll of a power boat and therefore one would have take great care that the sailboat's rigging was capable of handling the additional loads imposed up it.
In an anchorage 'flopper stopper type' para vanes do work in preventing as much as 75% of the roll of a sail boat

I have used the wing on wing a number of times, I love it a very nice ride. I never felt any rolling.

Now I must ask what do you mean by rolling?

It's a long standing multi-hull complaint about mono-hull vessels. I have experenced something similar on a power vessel.

If you didn't experence it, my hats off to you. However, it does seem to be a common complaint.

It has always been in mild winds or low winds. My friend Billy freaked out when I first did it on his boat.

I started sailing around 3 years ago and was very lucky a few people here would let me sail their boats and I would sail mine.

The way I learned to sail was by reading and watching Utube then I would get out there and try it. some how I did learn alot and I know of two people think I am a very good sailor.

Trust me I had a big learning creve been hurt a few times. but have always return to the dock. and been on a number of trips off shore.

I would imagine that a paravane would add far too much drag to be practical on a sailboat. Commercial fishing boats that use them have much more thrust with their engines to overcome the drag of the paravane than the sailboat could generate with sails alone in anything below a near gale.

Errr...NO...excuse me for shouting...just to many reasons, one
that comes to mind if able to deploy from a sailboat is the picture a vane, referred to a a bird in the fishing fleet, becoming
airborne with such force that it might...kill someone...put a hole
in the side of vessel...take out some standing rigging or the mast...but you probably won't have to worry about any of those
hazards because any booms capable of deploying birds would
capsize the boat and keep her there after the first knockdown
caused by said booms.
Sorry for tone of post...I truly like thinking which is outside the box...but could we start with some thing with a little less hazardous..say like...otterboards at least they might just slow you down!

Guess it would stop the rolling - but probably only because it would stop the boat!

A simple towed generator will knock 1 knot off most boats speed, goodness knows what effect such a contraption would have.

Methinks easier solutions are there - like just sailing better angles.

Why would they do that on a sailboat if they don't on powerboats? I think properly deployed they are deep enough to stay put. Still probably not a good idea but I can't see why they would be any more dangerous then on a power boat.

If my boat rolls, we just change course a little so we are not sailing directly downwind. Keep the wind on the aft quarter and throw in a jibe after a suitable time to regain your course - much more comfortable way to go!

On my boat, a 62ft motor cruiser, paravanes cost me around 0.4 of a knot. I've never seen nor thought about them on a sail boat but I imagine the gear, which would have to be a fixed instillation, would preclude efficient sail management. The booms, when stowed inboard are a big bit of kit and deployed they more than triple the effective beam of the boat. The stress imposed on the gear are very high when mounted on a motor cruiser. I think that on a yacht with a decent amount of sail set, the stress would be another order of magnitude higher. It's probably doable but that would be at the cost of most of your sailing ability.

just my 2c
