Permatrim Hydrofoils

Greetings! I haven't read back through all 8 pages of this topic so I may have missed it, but does anyone have feedback on installation of Permatrims on twin engines on a CD22? I have an angler on order at EQ and have opted for twin Honda 40's. Part of my decision was that I didn't want to have regular trim tabs installed. I had a set fail on my old Glasply and I never felt I needed them on the 22 Cruiser I just sold. Les indicated that twin engines, because they can be trimmed differently, provide (limited) side to side trim ability. I am very intrigued by the permatrim, however, because of its simplicity and downturned sides. My 22' cruiser had a doel-fin and the lighter 70Johnson, and I never felt like I wanted to add much more weight to the stern. The boat handled best in rough water with the nose down. I would appreciate anyone's thoughts, particularly those who may be familiar with the 22' Angler. Thanks a bunch! Mike.
 
I too am interested if someone likes them on the cd25. Even with trim tabs all the way down I slow to speeds under 6 or 7 mph in chop.
I also want to know how they effect backing into a slip. Do you lose any control backing?
 
Hello Mike, We have a 2001 22' crusier twin 40 HP Hondas. about two years ago I installed the Permatrims. I am very happy with them, it improves the ability of side to side trim greatly. It takes just the slightest trim on one or the other engines to level out the boat. I thought long and hard about trim tabs and decided to try the Permatims first. Since I installed them, I have been very happy with the results. They are a first class product and add to the overall handling of the boat. As you can tell I am a big fan of Permatrims. Hope this helps, Big Mac.
 
Jeff,

I have twin F80's which add a little more weight to the stern than a single. The main purpose that I'd have to add the Permatrims are to assist raising the stern with less angle on the trim tabs. The more angle you have on the trim tabs, the more it cuts your efficiency through the water, and thus, your gas mileage, but some of this is offset by the better hull attitude overall allowing it to slip through the water easier.

Someone told me years ago, you can't have too big of trim tabs on most boats, but there is a physical limit of course. This idea seems to fit logically to provide more lateral surface area to spread the load even more with less of an abrupt angle of the trim tabs. Plus they would be even further aft of the stern as I mentioned which means more leverage with less angle. I'm going to continue to pursue this, it's looking pretty good.
 
On the Tom Cat it does not make any difference in backing. I am holding my opinion on the 25 until I have a chance to run it with the trim tabs working. The engine trim alone did not get the bow down enough. I personally prefer trim tabs for getting the bow down.
 
I got a permatrim for my Honda 90 this winter and after 2 trips totaling 18 days on the water I am completely satisfied with it. With 80 gals of fuel and 200# of fish along with everything else in the cockpit I could get the bow of my 22' down into the seas. Money well spent
 
Even set level, the trim tabs seem to help hold the bow down. I think this is somewhat like a longer hull length effect.

If all they did was allow me to take the pounding out of driving home into steep waves after a long day at sea, they'd be worth it and they are. We were routinely heading home after 12-14 hours in 3-6 foot seas and it's hard to tell you how wonderfull it felt to just tip those Permatrims down a touch and smoothly cruise on home! Yes, I know I probably used a gallon more gas...

As said before, most of the time they give a good effect just set level.

I made a post on what did you do with your C Dory about the Permatrims a couple of days ago. We had some very nasty wakes to deal with in close quarters--Three 64 foot Sea Rays all in a row (probably a delivary run)--in a congested part of the ICW. Of all of the boats around us, we did the best, including a 35 foot Pursuit. We were going about 32 knots in the Tom Cat 255. We brought the throttles down and hit the very steep 5 foot wakes at about 11 knots--just whished over them--no significant slam, or pounding--and definately an improvement over what it was before the tabs. Hit the throttles back on up before we were completely clear of all of the wash and climbed back up on top.
 
Hi Folks,

Has any body put Permatrim on a pre 1986 (flat bottom) 22' C-Dory? If so, how do they work. I have no trouble getting the bow down at speed. What I have to do is raise the engine a little because the boat feels that it is going to dive in to the water to starboard from the twist of the prop.

Hi Fred
I have a 83 classic and 90 Ficht on her.
I installed the permatrim and I like it a lot.
it realy helps at lower speeds to give more control.
it does help to bring the bow down at higher speeds faster
 
I just finished a weekend using C-Horse with my newly installed permatrim on a Honda 90 (no trim tabs). We had heavy winds in the afternoon and calm conditions in the morning. The permatrim helped the boat's attitude tremendously in getting the nose down. Now I can finally see over the bow without stretching upwards. Great product!

We have twin Honda 40's on our 22. We have both trim tabs and permatrims and are very satisfied. We use the trim tabs for lateral trim and the permatrims for fore and aft. We are very happy with them and have used them for over five years.
