Iím interested to learn more about the Quick units. Seems to be less overall cost associated with them. Iím going to get a gyro just not sure which one yet. Thanks for all who have contributed to the conversation.

I did the glass work on 54 Bertram. I had to glass in 2 laminated pieces 1.5 in coosa board to existing stringers, then put 1/2 in. glass over existing stringers and coosa, then I glassed in 3/4 in. steel plates that had been drilled and tapped to fit the seakeeper 9.
I then put 1/2" glass over the whole new stringer system and original stringers as well. 875 hrs on the seakeeper and all is well.

I am probably going to install one end of the year. Waiting to hear some feedback from a few boats I know getting them now. Hard to find info on them but basically from what Iíve gathered they were commercial applications and quick bought the company. The price is less by a good bit and the install is easier because of not raw water plumbing hookups. In theory the reliability is/should be better with these units but they do not claim or try to advertise the same roll reduction as seakeeper. Seakeeper in the right application likes to claim say 90% reduction for example but quick would only say 60% in the same application (not firm numbers). Thatís not to say you couldnít install one and get 80% but they just donít seem to be going after that market. Thereís are more commercial in application and switching to the recreational market now from what I gather. Seakeepers are problematic. When they work they are great but before you drop $100k on one ask around. Not uncommon to talk to captains around here who will tell you they work only half the time.

We strongly considered one on a upcoming build of a similar sized CC. Primary use is running out ~50 miles off GOM West Coat. Reasons we did not.

1) came to the realization that the seas we would really love to dampen when fishing are the same seas we still donít love riding out in.

2) given the spool up and spool down/cool down time it could be a bit inconvienient. Albeit I believe they have made some improvements in those times since we looked.

3) if you look at the cost of the units, maintenace and increase fuel usage over the use of your boat, a larger boat which addresses some of the issues, becomes a realistic consideration.

4) we dont love running the genset, which you need to on the larger units.

5) this one may not be logical, but feel a bit uncomfortable with the concept of 600 lb ball spinning at 7000 rpm while offshore, should something go wrong.

If we were running a slower sportfish, cruiser, downeast, etc. or had a shorter run to fishing grounds I would see more value

power draw is about the same. Spool up times a few minutes less. Some claimed benefits are air cooled, ease of installation and overall smaller and compact. Supposedly they are maintance free. If and when they break they can be completely repaired in place. Very few boats have them in the states so far. I have talked w most of the captains running them. Roll reduction is good to great. Some of the early issues are not enough air flow in compartment leading to overheat.
Hopefully in a few weeks I will give a full report on quicks.

they will retrofit them on cats, but was told cats use the next size up due to multi hull. I tried to get one on mine, but could never get a quote from a few dealers I tried. Ended up with another boat anyway.

Did you feel the cat would benefit from one ?

is is exactly what I wonder about from the perspective of a false sense of security and people ending up in over their heads so to speak.
Iím interpreting this as Ďtoo rough because on gets sickí As opposed to unsafe.

Default Careful!

My seakeeper came loose, nightmare! Took out the generator. Lucky that it did not hole hull.

I own the original Seakeeper boat. Not 1 issue with stringers or structural integrity and its had a Seakeeper in it longer than any boat out there. I invite anyone to inspect my boat anytime.

Definitely makes a difference drifting, sitting and even running.

35' MJM, amazing difference. It eliminates a huge amount of rolling, but not as much "bow up and down". Why? leverage. MJM's are narrow, and the seakeeper does a fantastic job.

The seakeeper does nothing for pitch ( bow to stern movement) . no anti roll device does.
It is the natural physics of a gyroscope. As it processes for and aft it produces forces 90 degrees to the swinging axis. Swing for and aft you get side to side forces,. thus reducing the roll.
It may sound great to stop the rise and fall of the bow, but think about it. Stop the rise of the bow and you plow through everything. Especially in the ocean, you would not ride up and over the waves. Just crash into every one of them.

This cannot be repeated enough. I donít understand why thatís so hard to figure out by some. Never seen such pettiness. Itís like a compulsion.
