I have a 2000 18 Dauntless and would like to know if the place ment of the tabs, either lenco or bennet will interfere with the boat ladder.
Would appreciate a pic or two if anyone has them on their boat.
I hope I posted this in the right place, maybe it should be in performance or repairs and modifications?

The brand of trim tabs being used could possibly affect their placement because of concerns for routing the actuating lines to the tabs. Trim tabs made by Bennett are actuated by hydraulic lines, while trim tabs made by Lenco are actuated by electrical wiring. There may be differences in the placement of these two products that result from this difference in wiring.

With a small boat, space on the transom is limited and it may be impossible to locate all the devices that you want without having to make some compromise about their locations and interaction.

Fixed boarding ladders on the transom are handy, but you might consider how often you plan to use the ladder versus how often you plan to use the trim tabs. Make your decision about which device has the highest priority. A fixed transom mounted boarding ladder can always be replaced by a temporary over-the-gunwale style ladder.

All depends on the ladder. A ladder that drops straight down the transom will be a problem. it will also be just about impossible to use - with tabs or without due to the angle of the transom.

I put Lenco 12x9 trim tabs on my D15 - great addition by the way!

I also added a ladder from after i had the tabs in place.

The ladder flips down right over the tabs. Because of the angle of the transom (top is farther aft than the bottom) and because of the angle of the ladder, there isn't any interference - in point of fact, it isn't even close.

I put on the ladder that has the little platform. This also moves it out another 8-9 inches or so. However, I don't think there would be a problem either way.

Another plug for the tabs and ladder. The Tabs have given me wonderful adjustability over the boat's ride and performance - a great addition. I preferred the Lencos because the installation was simpler. The ladder that I chose is really great. It is the most solid and substantial ladder I have ever had on any boat ever. Highly recommended and a nice clean installation.

I put 12X12 lenco tabs on our 1998 OR-20 and had the same concerns regarding the swim platform/ladder. They clear just fine for horizontal access to the swim platforn BUT I had to order a shorter "angle mount" style so the actuator could be mounted under the platform (for proper vertical clearance). So you will need to measure the distance from where the tab mounts(edge of transom) to the most superior point of where the actuator mounts to the transom. This measurement is to be compared to lenco or bennett mounting diagram so you will be sure there is enough room for the actuator to be placed under your swim platform. Ours was pretty tight but the numbers worked! Also check with BW as they may have some suggestions too. Note: our 1998 OR-20 swim platform was stock from BW-if I can find a picture of it I will send it along.

Good Luck,

Thanks for the replys. The Dauntless has the,quote, euro transom and the boat ladder is part of it, I guess I should say it is just bolted through the last flat area on the stearn. Place ment and distance from the transom, may be enough, have not measured it, do not know exactly how far back the tabs will set. Also the distance from the keel may also be a problem the ladder is almost dead center of the right side of transom. Also this boat has the notch in the transom so positioning the tabs could be difficult and had hoped some one else had advice or experience with putting the tabs on.

I'll try that again;

I got real close to putting some bennett sport tabs on my 18' dauntless. I may still do it this summer. I did some measuring, and it doesn't look like they'd interfere with the ladder. The ladder goes out at an angle, and there's plenty of room between the ladder and the bottom of the transom for the trim tabs. I don't know about where the actuator goes, as I didn't consider then when I was looking into it.

If you put trim tabs on, let me know how much of an improvement you get!

Call the tab manufacturer and ask them. In my case, they were very familiar with the boat and had experience with a number of others. Bet they have looked at this with the Dauntless 18 more than once already.
