Formula boat porpoising

LIforrelaxin · 10-02-2019, 10:48 AM

I think that test report says it all.

While you could try new props, I don't believe you will find it that rewarding. I have reproped a few boats, and never noticed, and effect on the effectness of trim. Gain a better hole shot, or faster speeds is really what re-proping a boat does for you.

My personal opinion, is don't get caught up with the trim guage. the are known to be problematic. I really believe the most economical solution to your problem is as I stated before... Put the tabs up, and spend time understanding the boat, with just the drive time. Figure out where you want it, and then leave it stationary and let the tabs help you with everything else.....

Now if you are interested in spending money to get to a better situation, I suggest looking into bigger trim tabs.... the with lengthen the running surface, you should be able to trim up on the drive some more, and then use the tabs to settle down the porposing...

Good advice there.

I don't use a lot of trim with my 260. In certain circumstances I will trim up and use the tabs to settle it down, typically when it's really rough. There is a sweet spot that gets the drive line running nice and smooth, that's what I seek mostly.

Generally I think the Sun Sports are heavy in the butt end, trim tabs are a must for sure. I had one of the switches fail once and I wasted no time replacing it.

Agreed Jason, even though that Formula measures as a 27, the hull really is not as long as it appears with the boat sitting in the water when you look at the image posted by the OP.

Isn't that like all boats today? A modern "210" is actually a "190" with 2 feet of swim platform. It bugs me so much how brands do that today with their naming conventions.

I'm glad some still try to avoid it though for the most part. Formula is one. Like this "270" actually has close to 27 feet of fiberglass underneath. I think it's listed as 28.5 on the spec sheet with the extended platform you have here.

My 2008 Sea Ray 240 Sundeck is 26'4" or so.

The newer ones are about 2' smaller.

Good catch!

Thought the end to end measurement of the boat is well over 28' the running surface of the bottom ends well before the end of the swim platform, maybe 4'

The layout makes for an interesting balance and centerpoint for weight.

It had a great ride in Winnipesaukee water conditions.

We just moved up from a 23' Caravelle Interceptor with a good size swim platform pushing its end to end length to 25', but for the few feet difference the Formula is a totally different boat.

Much heaver, better rough water ride, more interior space, but MUCH slower overall and doesnt really loosen up like smaller boats at higher speed and higher trim levels.

Not complaining at all, just observing its a very different experience than all my other previous boats.

So far we LOVE it!

Its always good to end up being happy with a purchase of this level
