How much of a difference is the DV compared to the SDV on the 18'6?

SDV = 16,5degrees deadrise in the stern
DV = 21 degrees

thanks BFC. So would i be correct that the DV is a better ride in rough water but the SDV would roll less?

For me I prefer the SDV / Modified V. And the trick is the boat must be lekker heavy. SDV does roll less.

one Shortfall some of these older mono's have is the lack of a big enough sprayrail, compared to the American boats they have huge Sprayrails, and that creates a lot of secondary stability also making a softer ride.

Attached is a picture of a newer monohull design from Fusion Yachts in Knysna and from a design perspective they are following the newest IMPROVEMENTS on a mono, big sprayrails and deep V and widest portion of the beam is aft instead of the shoulder of the hull,that is good for stability, plains easy, less power needed.

Yas!

Nice to see you okes have been so busy here!


BFC,

"Improvements" is a relative term in this case

The stability and easier planing comes at the expense of seakeeping/worthiness, i.e. on the ocean the hull of a boat crests, and then falls into the troughs behind every swell

What makes a boat seaworthy and safe is the ability of the bow to resist and rise without swamping. Which is why the flare and beam (displacement) at the shoulder is so important

The fusion hull you posted is not going to cut it offshore

Especially not in a short period swell (5-6 sec) as we get with the NW in the Cape. My boat, which I consider really seaworthy, has had green water halfway up the windscreen under such conditions

That is a fairweather boat at best

wara wara wara ,

You are preaching to the converted, info was just a FYI.

A opportunity came along and we are 4 mates that bought this boat yesterday, its a AceCraft 660 SDV with 2x115hp Mariners and built like a brick shithouse !!

wrt the 18,6 DV, I consider it still to be a modified DV

I will take a pic of my hull tomorrow and post it...you will see it is much "deeper" than the 18,6 DV, in other words a true deep vee hull

wrt to surflaunching and turning between sets, this should seldom be necessary if you are experienced and your timing is right

But yes, a deep V was designed to sit in it's groove and not slip, but track straight, which is why it is superior in seakeeping, at the expense of a wider turning circle

Here is about the sharpest I can turn my boat on the plane...I guess at least 40m is needed!

 

[thika]

Congrats!

I know the boat..from Witsand and used to punching waves

 

[benniejordaan]

The length of the boat and the speed will determine the turning circle. FYI..

If I was going to choose, I would have a deep V for a better ride.

18,6' DV :

 

[thika]

660 full DV hull as compared to the modified DV of the 18,6 above:

Difficult to keep on level keel and falls very deep into turns, but eats rough water and is completely dry

18,6' DV :

Is this your boat?

BTW, the triangle is on the wrong side. Supposed to be on the right.

No Doris

I don't live in GP...Lodie is my Boat

Point I made is that the 18,6DV is still a modified deep vee and should therefore still have reasonable manners

The 660DV is a "true-er" DV

Here's another pic:

Yes chop, I know but you moved to where you are now, who really cares where you came from.

Cat owners smoke too much DP.

Then the zol packs in their brainfat and then they are induced
into a permanent deurmekaargyt

Thats why they cannot remember Thika has a 660DV and hails
from the Lowveld!

 

[Craig.fish]

At last......Ready for trials and fishing!

 

[HelloC]

Bliksem that is a nice rig...

What was the build cost of the boat at the end of the day if I may ask ?

 

[Fishfun]

Toooo much of beautiful....enjoy the trials, she will be great

 

[thika]

Congratulations Craig.fish!

That boat of yours is very capable in rough water

Eaaaasy to tow

Easy to launch and retrieve

May you have many fish and see beautiful places in her

 

[sakn]

Great looking boat.

I see the boat is night rated. Where is the 112.5 degree port light located? Also the masthead light?

 

[Craig.fish]

Thanks all.

Nav lights mounted on the CC. White lights are plug in's.

 

[thika]

Why the wording "NIGHT RATED" on the boat?

Think it is more important to have that wording on your skippers ticket than on a boat
