in Feb of 2007 I bought a "Permatrim" from Shipyard Island Marina, Inc.
for my 19ft 2004 C-Dory Angler; equipped with a Honda BF90. I spent
hours researching a solution on this web-site and others, on how to
correct some handling (porposing) problems I was having. Please keep in
mind, I knew when I bought this boat, it was not-nor-never was designed
to be a "speed-boat" by far, but I ave had allot of boating experience
in my years, and I knew it could operate safely at a much high speed
then C-Dory claimed it would.
I promised, I would give all you some feedback on the results after
installing this product to inform you if it helped correct the situation
I was experiencing.
-My feedback to you is as follows; The
Permatrim product I installed on my boat, not only corrected the awkward
rear slide action in less than ideal water situations, it has changed
the handle on the vessel completely. I could swear I would never have
known it was the same boat. I still do not fully understand how
something so simple in design and size could make such a huge
difference. I have been a boat owner/operator for 25 plus years, have
owned several different boat types, never have I made such a simple
upgrade that would make such a huge difference. The installation
instructions provided (.pdf format) by Shipyard Island Marina, Inc. were
spot-on, easy to read and easy to do. Total install time was about 15
minutes. A special Thank you to Mr. Andrew J. Munao, Jr. (Shipyard
Island Marina, Inc.) for his help and advice on the entire subject.
boat now handles like it is supposed to, it planes quickly and responds
to steering like a sports car. I even got into some very nasty water
conditions (4-5 ft swells, cross wind and confused current), these
conditions occur at times in Prince William Sound Alaska around heavy
island structure. In the past, before the Permatrim, I would have to
slow roll the boat down to about 10 kts, and lumber through it for
safety and comfort. With the Permatrim installed, the boat tracked true
and safe, and I was able to operate at a safe speed of 20-22 kts.
other note to pass along, the boat came equipped with two Bennet Hyd
Trim Tabs, before the Permatrim was installed, I had to keep them in the
FULL down position at all times, now I can run them in a neutral
position and use them for their intended purpose.
-It is worth
twice the price I paid. Please use this testament to any other C-Dory
customers, that this product will improve their boat handling, even if
they don't have a real problem to speak of.
- One Last note:
prior to the Permatrim I ran a 3-Blade; 15 pitch prop, I kept a 3-Blade
17 pitch prop as a spare. The Permatrim's new balance allowed almost a
300 RPM gain on the top end with the 15 pitch prop. I swapped over to a
4-blade; 15 pitch prop and now I tach-out 5900/6100 RPM (WOT) which gave
me a 7 knot gain on the top end (thatís a BIG gain in this little
boat). Last weekend I bought a 17 pitch-4 Blade prop to tone it down a
bit, I can't wait to try it out. I am overly pleased with this product.

andy, ust a follow up to let you
know how the Permatrim I purchased back in Jan for my 19' Sea Swirl Striper
Honda 130 hp performed...I just got around to testing it and it worked
out perfectly! i did remove the Honda kicker motor (for fishing) to do away
with added weight and with the Permatrim installed the RPM's went up to
6000-6100 WOT and the boat planes right out of the hole in about 50' !! It
looks like a factory Honda part on the motor and was fairly easy to install
with detailed instructions..very satisfied customer and appreciated the advice.
