I'm looking at purchasing a 23 Whaler and
I'm sold on adding trim tabs.
Are they difficult to install,and would
single pistons do the job?
Backlash had mention trim tabs,How close
are tabs mounted to the sides of the boat?
Thanks,Ed Stone

Ed might check out http://www.bennetttrimtabs.com/ for the information your looking for.
Also another alternative to hydraulic tabs is the Electro-mechanical trim tabs there are a couple of companies which offer them one come to mind is Lenco which Shoreway Marine offers up here in NJ. http://www.lencomarine.com/TrimTabs.htm

Hey BigZ,
Thanks for the Info,I would imagine there is
trim tabs on Amy's Whaler.
Now Thats a serious Whaler.I've enjoyed
looking at all the pictures of your 27.
Did you replace or add thru hull fittings
to your 27.In the latest photo are you
doing thru hulls or repainting the hull.
Thanks again.

Actually Ed we had just finished putting "Amy's Whaler" decals on that day --- two person job so the "chairman of the board" was enlisted to help -- she had the camera with her --
At that point I had finished painting the bottom for the second time, had a shop in FL do it early in the spring their stuff had worn off by the time we got it up to NJ -- and the through hull which was in the transom sump was the only one replaced --- it had been pulled out and we were letting the water which had gotten in the foam core slowly drain out --- later I took more drastic measures removing the water and then finally had the drain fiberglass/epoxied back in place --- there are 4 more below water line which will be re-done this winter (none were leaking though) with a different type of fitting which should last ---

Hey BigZ,
Thru hulls thats like open heart surgery on
a Whaler.I seen pictures of a test they did
with the whaler foam to see how much water was absorbed.They said it only absorbed
fluids in a small portion of the surface.
And that was free exspansion foam.

Ed,
Forgot to mention, yes we do have the original Bennett trim tabs on A's-Whaler. However one hangs, lets see think the starboard, not cool so I didn't bother when we had her out to get it fixed or replaced -- chuckle had spent to much $$$ as it was on the other priority problems!
Not sure what BW showed you but if you have a 2" hole cut through the foam between inter and outer hulls let me tell you it just don't absorb "fluids" in a small portion of the surface --- the fitting is about a foot up from the keel there was saturation around the hole all the way to the keel! When I finally used suction with a vacuum pump pulled about 2 gallons out and god knows how much by capillary action dripped out over the 2 months she was high and dry --- every time I was down there in bone dry weather a large wet spot was present in the sand---

Hey BigZ,
I did not see or hear this first hand it
was through a dealer.So we can take it for
what it is worth.He did have pictures.
It showed a container with a tall plastic
tube with various lines drawn on the tube.
The liquid foam was added to the container
and without being under pressure rose to
a free expansion level.They cross sectioned
that into pieces and compared it side by
side to a piece of compressed foam.Both
pieces only absorbed fluids in the outer
layers of the foam.
Now I was wondering If a dealer would be
competant enough to do a thru-hull fitting
with enough care to seal in and around the
gel coat,glass,foam and fitting.I'm still
skeptical about how much water the foam
will absorb.
