Fore spar flop per stoppers

We use the Forespar flopped stoppers, depending upon the roll in the anchorage we sometimes use 1 , if needed we deploy the other. We use 8mm non stretch lines on the system. We weigh 36 tonne and 57 foot long with a 5.2 metre beam. The poles are 4.2 metres long, so we take up about 15 metres in width. The Forespar system comes as a kit , with poles, fittings for each end and connection to the vessels, it also includes the stainless hinged flopped stoppers. They work extremely well stopping probably 80 % of the roll and really slows the motion up. They are fairly easy to install. The higher the rope attachments to the vessel above the outward poles the more effective they are, giving them greater leverage.
Happy we have them as part of our kit when needed.

Cheers Chris D LIberty 2015

Using a second anchor to slew the boat into the swells frequently works and is little effort and no cost.

I was looking at the forspar ones and was wondering did you have to put any reinforcing in where they were fitted. What sort of strain do they put on the boat where fittings are.
I am concerned that the strain maybe to much for my fiberglass flybridge.

If the underwater inspection on the new 60fter goes well I will look at doing a pre-emptive strike and make up a set.
Thinking a setup like pictured earlier,

but from 50mm ally tube.

The actual unit I was thinking of this type

as I have a selection of Aluminium Amplimesh security screens in the back shed that are marginally larger than the magma ones.
I also have several sheets of acrylic as used in kitchen splashbacks, so thinking that, the frames and some nylon but hinges will be an easy and affordable DIY arrangement.

Hey Simi 60,

An amusing follow up to my posting of my setup above-

I was told by the previous owner that he had designed and had fabricated the system himself.

Funnily enough, I found a photo of my boat's system in the real manufacturer's brochure.

Boat Stabilisers | Boat Stabilizers by Ocean Torque

They are well built and work well.

One of the nice things about the Magma plates is that the fold up, slip into a bag and are easy to store.

One of the bad things about them is they cost close to $1000 here vs a few dollars for my DIY given I have it all laying around anyway.

As for storage, on those arms shown above its easy enough during fabrication stage to make a bracket on the arm that the flopper stopper can be stored in.

They are $320. But I was talking about their style, which is easy enough for someone to knock on their own, rather than suggesting that you buy them.

As to storage, personally I think all that heavy duty permanent rigging makes a pleasure boat look rather junky. And few rigged that way seemed to be used for any real passage making away.

But as always, YMMV.

Like I said, here they are near $1000.
$798 to be exact

As for your comment on heavy duty permanent rigging, logic says that they are being used, hence the need for it.
Those tied to a marina berth have no need for it therefore, would have no need to have it installed.

I am also thinking about roll stabilisers for my GB46, as we anchor out a lot and some nights roll can be annoying. Have any of the other Grand Banks owners here installed them and, if so, any thoughts/tips/suggestions for Grand Banks specific installation would be gratefully received. Thanks, Hamish.

I didn't catch you were in OZ.

Logic doesn't really apply to much of how people rig their boats and really use them from what I've seen. But in OZ, it could be a different story.

On my old 42' GB I used both the Davis cones and the Magma plates at different times with great success.

While I used them both with and with out poles and the worked in either case, the added leverage of the poles of course really helps make them more effective.

capt bill11,
Did you use two (2) ? as in one on each side of the boat ?.
I cannot imagine how only one would be very effective as in the Magma illustration.

I know some Sailboats in the Caribbean use only one connected to the boom and it seems to be very effective.

Yes, one on a boom or arm ie effective. But two on arms are even more effective.

Because we suspend our dinghy out of the water each night on the port side (security) we only use our starboard side flopper stopper. Still quite effective.

If conditions are rough we may either lift the dinghy to the boat deck or trust because of the rough weather the thieves won't touch it locked to the stern. In either case we then use both flopper stoppers.
