Originally posted by nautiJohn:<br /> We manufacture Smart Tabs just so you understand and can weigh the comments we make. <br /><br />First it depends on the size and use of the craft. <br />However lets make some assumptions: The boat is 26 feet long, deep V hull, cuddy cabin, a 9 ft beam, with a 240 HP I/O, and weighs 4500 lbs. wet without passengers or gear. The boat is used for longer cruising and over night trips, off Shore. Our recommendation is use helm controlled Trim Tabs at least 18" wide by 9" deep. We do not make Trim Tabs for this market.<br /><br />Let's make the second assumption: <br />The boat is 20 feet long, 7.5" wide, with a 210HP I/O, open bow, weighing in at 2700 Lbs. It is used for cruising the lakes, pulling skiers and tubes, and some fishing. We would recommend Smart Tabs ST1290-80. They should handle the average load balance issues in any boat this size. If the list was permanent, such as a torque list or Kicker motor installation, the Smart Tabs can be adjusted independently to compensate for the list. If you have more radical correction needs we would need to know the details before recommending either type.<br /><br />What you give up in a smaller boat situation when moving to helm controlled tabs is the following:<br />1) convenience and safety on an automatic system<br />2) an active system that not only provided an improved ride and better handling, but unmatched tracking at both low and high speeds. <br /><br />We will leave price out of the picture at this time as it was not part of the question which is related to peformance only.
I'm 100% with Tabman on this one. <br /><br />bpOriginally posted by Tabman:<br /> rboat99,<br /><br />Of course like John I am biased since I work for Bennett Marine. We feel that remotely adjustable Trim Tabs give much more control over passenger and gear loading in all size boats, particularly smaller boats where the weight of passengers, coolers and gear make up a much larger percentage of weight and have a much more profound impact on boat trim then on a larger boat. I am a big guy, but when I walk aground on a Viking 65 my weight does not really impact the boats trim. However when I run a 16 foot flats skiff my weigh has a big impact on the boats trim. And the way I load the boat is never the same, even on the same short trip. My wife and daughters like to move around depending on the sun spray, and or view. I might have a cooler full of ice on one side one day, and my equally heavy buddy fishing with me the next day. Yes they do cost more and take a bit more time to install, but for me on a small boat the ability to correct for weight distribution on the boat on the fly is the best way to meet the changing conditions and get the best out of the boat. Remotely adjustable Trim Tabs do not take constant adjustment and trimming both the fore and aft and side to side adjustment to meet the current conditions is invaluable. If the boat is stern heavy I can dial in lots of Tab for a great hole shot and running with my daughters riding up in the bow I can keep the bow where I want it in a following sea or at any speed. Just like aircraft have remotely adjustable flaps for different conditions so should boats.
