Boat complete. Next step motors!

Amazing to witness how much labour and hands on effort goes into building a boat, and even more surprising that when you do the sums the actual hull is a small portion of the build cost compared to motors and electronics.

Who is the builder? Is it Jentan Marine?

 

[CBass]

Bennie, looks like the builder is top secret......unanswered for a while...haha

Looks like natal powerboats perhaps?

The 15,6ft Moulds are in the hands of Tri-boating Isipingo.

I assume it is also they who are doing the Build.

BFC did you not own them at a stage? Did you sell them?

No secret....just been out the country for a week. Tri-boating owns the 15'6 mould.

Touchy bunch

I own the 16,6ft Moulds

Here is where all the known AceCraft Moulds are:

I only know of 6 original AceCraft Moulds in existence.

15,6 = 4,65m L and 1,9m Beam (Tri boating)
16,6 = 5.1m L and 2.2m Beam (Myself)
18,6 = 5,65m L and 2,4m Beam (DV-Triboating/ SDV -Natal Sharksboard)
21,6 = 6,6m L and 2,6M Beam ( DV- Anchor boatshop)

555- AceCat ( Magsons Marine)

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

DV to SDV has different Chine pattern.

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

Main differences...
Deep V will bag less.

Semi Deep V planes easier.

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
