There will be lots of thoughts and comments. This is just one.
Love the boat... but I'm biased.
You can master the chop with the rig mentioned but it will require limiting speed. Bigger trim tabs are not required but they will help you master the chop.
I could go on and on......but first some questions:
Where on the bay are you?
Will you be going offshore?
What boats are you familiar with?

I live on Tilghman Island and just had a Sea Ray 230 BR blown off of my lift last week and totaled. That boat pounded alot when I got into the bay
with even moderate chop. So when I replace it I would like to be able to make some speed.. I am not talking 30 kph but perhaps 20.
Would the deep v ride that much better ?? What do you think is a reasonable speed with moderate chop .. say wind 15 mph..(some whitecaps) ?
Thanks

The only way to know for sure "how much better" the DV is will be to compare the two. There is no doubt it will be noticeable.
It would be safe to say that the 2520XL in a 15 mph wind with the water just starting to white cap you will not want to go over 20. (now the boat will fly through that stuff if you had to make time.. you would just incur the "pounding") The larger trim tabs will really keep the bow down and allow for an increase in speed compared to the stock tabs.
The 2520 XL will be fine with the F225.... I would not want less than 250 on a DV.
With my rig.... and mine is definitely on the heavy side... I tend to cruise at 25 mph at 4500 RPM and get 2.5 mpg. I've got a 4 blade prop that one day I'd like to get worked on and have another inch of pitch thrown in to bring down my cruising RPMs just a bit (while retaining a good hole shot ...for shooting troublesome inlets with a full load of gas and 4 people on board is what I want the hole shot for..)
I'm off the next 8 days straight if you want to go for a ride!

Tabs -a must IMHO.
Installed a set of bennett 24x9's this winter and it's a whole different boat. Boats an 89 25 Sportcabin (2520 predecessor) mod Vee, same hull as current mod vee. Would pound in a medium chop at anything over 15-20 mph.
With the tabs I can get the bow down to where it's cutting the water instead of pounding on the flat of the hull.
Can run comfortably 25-30 now in typical Chessie chop without beating her. even quartering into the waves is smoothed out.
Tabs also allow you to adjust for windage and heavy passengers making the boat list.
Guys I know with the deep vee report a much better ride with tabs too.

Thanks for the response
Bow down means no slap or pounding.
I ride with NO SLAP!!!!! No pounding unless I'm caught going too fast or without enough tabs.
I had a 2520XL for nearly five seasons on the Bay and enjoyed the boat but...
...in a pilothouse like the Parker you are sitting far forward in the cabin and unless you have the tabs set so you are burying the bow, you are going to feel every bump in the highway on the hard chop at anything over 18 knots.
If you steer from the cockpit position, the hull of the boat at that point hardly ever leaves the water and the ride is pretty much silky smooth, or at least feels that way.
I have a 210CC now with the deep vee, and to me it rides smoother over the chop than the 25-footer did. I think it is a function of the sharper deadrise, the sternward control position, and the narrower hull of the 21-footers. The 25-footer is an ultrawide for its length...

The XL will also be more economical to run. Something to consider these days :?

I think you ought to come for a no obligation test ride on this boat for comparision's sake!

Because of the forward position of the helm in a pilot house, you are always going to get that "slap" your were referring to. Tabs will help, but it's not like riding in a center console boat...
Modified Vee -
More fuel efficient as it takes less power to get on plane and keep it there.
Will plane at a lower speed (as low as 9 kts with proper tabs and trim).
Less roll on the drift and at the troll.
Must slow down and trim properly to keep from pounding in short chop.
Deep Vee -
More horsepower required to get on plane and keep it there.
Speed to plane (and keep it there) is higher than a mod-vee.
Tends to roll on the drift or on the troll in a beam sea.
Can make for faster overall speed in choppy seas.
No one but you can say which is better for your purpose.
If you want to go fast(er), get a deep vee.
If you want better economy and are willing to slow down and trim properly when it gets bumpy, get a mod-vee.
There is no free lunch, and you can't have it both ways.
A Parker (even a DV model) is not a Contender, Regulator, or SeeVee, and we are all fine with that. :wink:
If you want to do 40 kts on the Ches Bay in a 2' chop, look for another boat.
If you are OK cruising those conditions at 20 kts in an MV, you came to the right place.

With the price of fuel, I'm happy I got the MV...I just slow down a bit when it gets rough.

You also have to figure how far you run on a regular basis. What is the sense in getting a deep v if you run less than 20 or so miles at a time. You arent spending a lot of time running anyhow. .. why spend the extra money on fuel and cost in the boat for the same top side layout.
Absolutely correct Greg. It is all about your particular needs, and what you want the boat to do. Everyones expectations are different.
Both models... the MV and DV, are great hulls and one is not necessarily 'better' than the other (which is the point I was trying to make).
I believe I would be happy owning either model, but with fuel prices what they are right now I'm glad I have a single motor on an MV hull. 8)

Acutally, it's not. I have the MV :shock: and he's right.

The bracket can increase your efficiency by 15%. So, if the DV had a bracket and the MV did not, you may need to add another 15%.
The bottom line is there are no straight formulas. It's a compromise no matter how you slice it. If you're happy most of the time, you are ahead of the game. Remember, we buy these things to enjoy them.
