Re: trim tabs
There are many threads around about trim-tabs, so for more info you should try the search function.<br /><br />Anyway, I am familiar with those and they are usually installed to correct a porpoising problem. Many boats are their fastest right before the point of porpoising, so manufacturers often set their boats up with that type of balance from the factory. If an owner either transfers weight unevenly to the stern, or battery options etc. change the originallly intended balance, they can actually porpoise at all loads and speeds and become very frustrating. Correctly setup trim-tabs (even those that are not adjustable from inside the boat) can make just enough difference to make a boat liveable.
