Default Seakeeper

anyone have an experience with them? Thinking about putting one on a 360 Grady white express. Looking forward to the feedback.

dont want to sound like an ass but did you search: https://www.thehulltruth.com/search.php ? tons of threads on it.

what are you trying to accomplish? there was just a thread with someone with a spouse that gets seasick and they were looking at one to solve the problem which most agreed it would not

please share some more details

Fished on a boat with one for the first time last November. It doesn’t work miracles, but it comes damn close. 39 CV. If you don’t want to spend the coin, don’t get on a boat with one. Once you try it, you’ll never own another boat without it.

I've been on Seakeeper's Contender. I think its a 32. It's pretty phenomenal how it dampens the roll. Retrofitting for me was prohibitively expensive.

Don't get me wrong, I thinks its great technology and has the ability to turn a real uncomfortable experience into a pleasant one , however there is a possible negative consequence that I am thinking about. I wonder if the technology will lead into people with insufficient experience overextending there confidence and getting themselves into real trouble.
Without Seakeeper there is a recognition of "it's to rough to go go out because It just won't be fun". Add Seakeeper to the mix and I wonder how many people will take the attitude of " hey I have Seakeeper, I can go out today and get in a day of fishing!" when they and their boat should damn well be sitting at the pier, because either they or their boat, or both are not capable given the conditions, but the presence of Seakeep gives them a false sense of capability and experience. The technology doesn't extend or increase the weather conditions one should be out in.

A somewhat similar scenario took place in inboard power boat racing about 30 years ago. The Jersey speed skiff class of raceboats mandated the use of 'cages' in the 1990's. Up until that time the drive and mechanic were just sitting in bucket seats and holding on. Driver experience was critical for not running the skiff in such a way that they ended up being thrown out of the boat (tragically over the decades there were some accidents where there were deaths due to people being thrown out, or one boat running over the top of another. .... In the 1990's "cages" (look like roll bars) were mandated to keep the driver and mechanic strapped into the boat. This was definitely a safety improvement, but there is also an openly acknowledged recognition that the level of driver ability and talent on the racecourse has noticeably gone down.

I know first hand 100% fact that several boats that had Seakeepers installed AFTER they left the factory without the factory having knowledge that one would be installed had their stringers ripped form the hull! No I won't list my sources. Just choose to believe it or not but do your own research before you put one in. A boat that was engineered for one will absolutely ride, particularly drift much better than one with out one no doubt. We have come this far with the "need" for one. To me its just another expensive "accessory" for the rich and famous.

I had the pleasure to ride in a new 34 Regulator with a factory installed Seakeeper at the FLIBS. It was amazing, especially in a beam sea. They repeatedly switched it on and off, and the difference was highly pronounced.

I believe they run about $50K, and come in various sizes depending on the length and mass of the boat. The gyro spins at some astronomical speed, and takes 20 minutes to warm up.

I know that if I were in the market for a boat in that class, this would be installed.

They also said they are working on a smaller unit for smaller-sized boats.

Good luck!

I have fished on a 43 Everglades with a Seakeeper. It is pretty cool tech and it does work. The first few times your body feels a little weird for lack of a better term because you think you should be rolling but you aren't but you get used to it. Its pretty cool the best I can liken it to is that boat seems to hunker down or hug the earth.

I also would believe a boat should be made for it . Just think of your 15k of boat falling off a lift and now it gets stopped by a cable bonded to a stringer. Now do that over 1000 times in every direction. And that’s for 1 fishing trip. I know this is a simple example but the lifting forced [ the force that actually stops the roll ] is almost equal to the force that started it. No free lunch when it come to action and reaction.

Actually, ............. the force that Seakeeper puts on the mounting frame MUST be EXACTLY the same as the forces trying to roll the boat around, or it wouldn't work. ----- That basic law of physics for every action there is an opposite and equal reaction.

All other points correct and well taken.

Our boat came with one. It’s a new boat (50 Cantius) and we have only been on one cruise so far. We went from Seattle up to Vancouver Island and had it on. In the straits there where 3+ waves and we where taking the waves from a beam and it did a great job minimizing the roll. We have a Seakeeper 6 and it takes about 45min to spin up to full RPM.

I wouldn’t want to miss it.

I am up to date on gyros. Installing three now. Location and space are the biggest problem. Have you measured or do you have a place to put one?

I have installed a seakeeper 5 in my Chris craft 42' tournament fisherman. Simply put Amazing tec! I will never own another boat with out one. Everyone seems to have something to say about them, focusing on drawbacks. Does the boat still rock? Yes it does, but mine 85% less. The biggest change is when it does rock, it does not rock back. The rock never get out of control. Look at it this way . Take a great day make it perfect. Take and ok day and make it great. Take a day you would not go , and go. These units do one thing extremely well. They make boating more fun. No more yelling at boats for buzzing too close, no more rocking on the hook from rouge channel wakes. No more spilled drinks in a 4' chop in the ocean. With all the money we spend on gadgets, fuel, mooring, the boat itself; these units give us what we all want MORE time on the water!

This,....... “Take a great day make it perfect. Take an ok day and make it great. Take a day you would not go, and go”

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.

That's an installation problem, I installed one of the big ones on deck of a 40 year-old commercial fishing boat who's deck was built with construction grade 2 by 4s, plywood and fiberglass, many thousands of operating hours later it's doing fine.

Then don't sound like an ass, every time a subject like this resurfaces new information is provided, just because it was spoken about a week ago doesn't mean everybody with pertinent information responded to the previous thread.

Well wonder no more. It is not a false sense of security. it is 100% real. You will have a safer experience with these units.

I quite disagree,
Yes, you will certainly have a more comfortable experience, ..... up to a point.


However, a Seakeeper will NOT turn a boat into something that it is not. If a certain boat is considered as ‘safe’ to be out in 4 foot seas when handled competently a Seakeeper will Not turn that same boat into one that is equally ‘safe’ to be out in 5-7 foot seas.
A Seakeeper will not prevent you from burying the nose in a short 5 foot chop or from being pooped. (yes a real term)
In a bad beam sea I would rather have my boat roll with the seas than to have it held level, you hold a hull level in a bad beam sea and it will be much easier to take green water over the gunwale.

Comfort and safety are two completely different things

It is exactly your thought and comment that concerns me. (See my earlier post farther up this thread).
