I recently purchased a 245DC. It is a beautiful boat and provides everything that the whole family was looking for. My previous boat was a bow rider and I am adjusting to the new hull design. I have read about positive trim and putting the tabs down a few clicks while getting on plane. I've tried it on the water and it translates well. However, I like to know "why" I'm doing something. It works it's way into my brain better to have the understanding behind the method, and it also helps so I can use the techniques to adjust to other situations. So, what exactly is going on? It seems that the motor trim is lifting the bow and the tabs are lifting the stern? Or is it more the resistance from the tabs? Or???

I have a 2360, similar hull but have twins. You should not need to lower the tabs to get on plane. These boats jump on plane pretty quick. I lower the motors all the way down when getting on plane then lift motors up a bit when on plane. I use the tabs to keep the boat running flat, meaning from leaning to one side. I also use the tabs if running into a short chop and want to smooth out the ride some by lowering the bow. In a following ocean sea tabs up always. These hulls are pretty amazing and normally just blast through the chop. Just play with it in different conditions and you will get to understand the characteristics of this hull.
Good luck, great boat.

Lowering tabs does improve hole shot/time to plane and helps to keep the bow down to improve visibility esp if running heavy e.g. full fuel, stern heavy load etc. All of the new automated tabs that are out now automatically deploy to some degree at hole shot for these reasons.
Is it required? No. I dont do it because neither my hole shot or bow rise is an issue for me as far as I'm concerned.
Lowering the tabs creates a lifting force on the stern which helps to keep bow rise down and mitigate the stern/motors from digging deep, this results in a slightly faster time to plane. Retract tabs and trim motor for maximum efficiency.
About the only times I've used my tabs on hole shot is if I'm running heavy and throttling up in shallow water like less than 3' which I tend to find myself in in NC.

I have a 2018 245 DC equipped with a 250 Yamaha, I think most are equipped with the 300. My hole shot is pretty good, i never mess with the tabs to try and get on plane and generally adjust the trim while running and leave the tabs alone unless like lainiej said, if I'm not running flat side to side for one reason or another. Occasionally, if I'm running in some skinny water I may trim the motor up and then use the tabs to put the nose back down, not sure if it realistically helps, but puts my mind at ease...
All in all my family loves the boat, does a lot of things really well, handles rough seas great, I've heard people say "it's a wet boat" but I think that's just something people like to say without any real world experience, I'll get wet occasionally on a windy day in a quartering sea, but no more so than on any other similar sized boat. Good luck with it and if you have any questions specific to the model, there's a few owners here who have been pretty helpful.

When I've got two older grandkids on a towable I use the tabs to get on plane faster and it allows me to see in front of the boat while accelerating. I also use them for load balancing and for lessening the bounce when heading into the wind especially when I've got people in the bow. Tabs should be up when running with the waves.
As far as engine trim I try to set it where I'm getting the best MPH and MPG if I'm going a long way. Otherwise I usually leave it alone while running.

Great replies. Thanks. The trim tabs are new for me, so I'm trying to figure out how best to use them. Right now, I have been using them to balance out the boat and to get the bow down in the chop. I didn't know if there were more situations where it was appropriate to use them. So, when I read that article, I started thinking more about them.
Overall, I am happy with the way the Sailfish handles the chop and wakes from other boats. One of the reasons that we upgraded was because our old boat would pound on the water in a little chop. Since we are only able to go out on weekends, we don't have the luxury of picking our days. So, as long as there is no lightening, we are on the water. We mostly stay on the bay, but I did get to take the SF out in the ocean for a bit and look forward to exploring that more.

2360 with twin 150’s here. There is an rpm zone from about 1900-2600 rpm I can not operate in unless tabs are full down. Boat also steers better in no wake zones with tabs full down.

Mine is at a high speed troll between 18 to 2300 rpms depending on sea conditions.

You're using them the right way, don't overcomplicate things.

Depending on conditions, I’ll use my tabs at cruise like the article describes...it’s the most efficient way to run my 2860.
At my normal 30mph offshore speed, adding a little tab and getting more hull out of the water will usually gain me .1-.2 mpg in fuel burn.
I think the ability to run this way depends a lot on where you boat; I’m in the northern GOM where the wave period is usually only 3-4 seconds so it’s easy to span the waves with a little speed. Obviously it’s also easier with a longer boat.
But just give it a shot...trim the motor up and give it a couple clicks of tab...you should feel the hull slowly rise up...if not, try going a little faster. Make slow, small changes and try to maximize your speed and fuel burn to find the most efficiency.

That article is refering to cruising in a wet boat, getting on top of the waves to dry out the ride. That only works in chop though. When the waves are 3ft and 4-5 seconds its not going to work. Relevant to this post though, that article/ video has nothing to do with getting on plane. You should have the engine trimmed all the way down when getting on plane, then trim up until it porpoises, then bump it back down. Then you adjust the tabs as needed. If you want to use tabs when getting on plane, go ahead and see how that works. Maybe it works well for you. Positive trim while gettign on plane is conter productive and would likely extend the time it takes to get out of the water.
