OUTBOARD Accessories?

Hello all,

We have a 2006 22' Cruiser with trim tabs now powered by a new Yamaha 100 (great motor BTW) and have always had issues with "sliding or skidding" off the crest or slope of a wave so I'm looking at ADD-ON accessories to improve its performance...

1. Has anyone added a PERMATRIM to their outboard motor and is it helpful?
2. Has anyone added a HYDRO-SHIELD to their outboard motor and is it helpful?
3. Does anyone have a better fix, solution or suggestion?

Thanks!

I don't know about the sliding or skidding, but I have put Permatrims on both my earlier 22, and now on my 25. And it does make a big difference in boat trim and with cavitation. I don't know if I've ever experienced the sliding that you are talking about. I was in a lot of 2-4' waves in the PNW earlier this summer, and routinely see those kind of square waves in the Great Lakes. Colby

I have run Permatrim and trim tabs on most of my C Dorys. On the 22 with a 90 hp, it lowers the planing speed, It gives a little more stability.

Driving on the back of waves (don’t do the front--too much chance of uncontroled broach.) I find having the Permatrim, allows you to pick your speed lower than without it, and continue to ride the back of a wave.

If you were to come down the face (depends on the size and steepness (period) of the wave, the Permatrim would help. But again, skill in driving and using tabs are important here.

Not sure what you mean by "sliding or skidding". C-Dorys can bow steer if you get the bow too deep going down a wave. In rough water, you have balance getting the bow down for better penetration of the waves against the bow steering when you get to the trough. The biggest help is to slow down. A C-Dory rides like a cork, it wants to go up and over a wave rather than through it. There can be some corkscrew motion as the wave lifts the bow and then the stern when taking waves at an angle.
Trim tabs or a Permatrim are a good addition to any C-Dory. Trim tabs add lateral control along with pitch control that a Permatrim cannot. Permatrim mounts farther aft so it has a mechanical advantage over trim tabs.

I too, don’t know about the sliding or skidding, as I’ve only experienced something that might be described as that a few times. Once, when in SE Alaska going out to unprotected waters to check conditions, when the radio was saying 7 feet. I found just out of the passage, washing machine-type waves with them coming from all directions and the boat seemed to be sorta sliding or skidding off one just to be hit from the opposite directions from another. I quickly got back to the inside waters. Other times possibly when crossing channels & running parallel to short-spaced, fairly big steep wind waves. But in this instance most likely just the wave pushing the boat around some as they went under. Another, when improperly trimmed, and that’s the scariest as the bow digs in, the boat heels, and the stern starts around, but, never anything like described, other than as Ssobol said “the corkscrew motion when taking the waves at a angle”.

For the first 8 years, I ran with trip tabs & then added the Permatrims to our twins & they made for a huge improvement, especially where I run frequently heavy. Like others who have added them to their CD22, I wouldn’t want to run without them now. Along with the major added ability to trim & keep away from cavitation, I’ve found steering improved at slow speeds in tight places. Before the Permatrims, when making tight turns at higher speeds, I would get cavitation from the twin motor on the outside of the turn.

Being new to outboards this season, Iwas open to other’s experience and decided to add permatrim to my 25 cruiser honda 150 based on other cbrat’s experiences and wow what a difference in planing and as mentioned above control in lower speeds. Makes docking more manageable. It was an inexpensive improvement in my experience

I REALLY appreciate everyone's input. Thank you!
Has any one added BOTH a hydrofoil and a hydroshield?
I'm thinking of adding both but wondering if it's "overkill" -or- if one negates the need for the other....

Following seas trim tabs & motor trimmed up. If sliding back down into the ditch? Add throttle until over the crest.

I was not impressed with the Permatrim!

I have a 25' and have been considering getting permatrim to add on and want to know as much about them as I can before making the making the purchase. It seems that every comment I've read about them are positive. May I inquire as to what you don't like about them. Thanks

I'm a big fan of Permatrims. I have them on my 24' Tomcat, a 14' Livingston with a 40hp and also a 14' TrueKit Discovery with a 20hp. These are all catamarans. The permatrims came with my Tomcat so I don't have any reference without, but on the other boats they significantly reduced cavitation, kept the boat on plane at slower speeds, and reduced pitching especially when overtaking waves. I learned that on the smaller motors no drilling is required as the Sikaflex bond is enough to keep it in place.

I've never tried the permashield, but had some less than desirable results putting hydrofoil stabilizers on an outboard of another RIB and it rode super squirrely with them attached. I think of the Permatrim as something that can act as a counterbalance to give lift behind the outboard to help keep the nose down, and it also seems to magnify the trim control of the outboard. I don't have separate trim tabs on the Tomcat.
