Thread: The Cruise Control 520

G'day Everyone,
Here's a basic overview of the build process of the Cruise Control 5.2. Since I last posted pictures of the design, I've done a few small changes but one of the major one's was to change the deadrise angle from 15 degrees to now 20 degrees at the transom.
I rang Tony and after much discussion, he decided to go with it. In order to do this though, this also meant that I had to widen up the chine flats at the stern. Overall I was happy to do this as this also increases stability while at rest but also, it provides greater lift when getting up on the plane. While increasing the deadrise, this also meant that I could increase the deadrise angle at the bow giving a finer entry point. It also meant that in constructing the boat, the bottom panel was also easier to construct. Overall, I was pretty happy with the result.

Here's the process of building.
If you have any questions, please feel free to ask.



Frame Construction



All the stringer and longitudinals are constructed from laminated plywood



Bottom panel now on



Chine flat and topsides now stitched in position



The cockpit and cabin sole now in



The side decks now on.

Here the next upload

Mark



The cabin sides are now constructed and stitched and tabbed into place



Constructing the internals using the bulkheads as the starting fixture



Constructing the dashboard



Finishing the transom section



Constructing the cabin roof



Seats and bases now in along with the perspex cabin windows and windscreen and the rear quarter rail

Here's the last 3 pictures. Naturally there will be more, but these one's I won't bother posting here otherwise it will get this whole sequence out of order ha ha . So, I'll finally post them up on our website.

Hope you enjoy these pictures

Mark,

Whats the onerall size of the 520, and have you an idea at what the cost of plans will be.

Ken

G'day Ken,
The LOD is 17ft 1in (5.21m)

Including the bowsprit for securing the anchor, the LOA = 18ft 3in (5.57 m)

Cost of plans? I'm looking between $300 to $400 AUS

Gday Mark, Yep looks great with 20 degrees

It's a funny old world isn't it? I've been spending hours and hours looking for a centre console around the 5.6M mark which has a "true" deep V. Something around 20 to 22 degrees deadrise at the transom. Then coming forward to an even finer entry. For some reason I believe it would be a great way to smooth out the metre plus chop we get around here every afternoon when the sea breeze gets up. I've always loved consoles, in fact I own a Haines Hunter 5.2 Prowler at the moment. But what I really want to do is sell the Haines and make a ply over timber frame boat of around the same size to just a bit bigger.

There are plenty of moderate vee designs out there, though most of them are stitch and tape or composites. Not many real timber designs where the frames are timber and the skin is ply. I'd even settle for a ply frame set of plans with a ply skin. Narrow this down even more by looking for a deep vee and it's pretty lean pickings.

Perhaps I'm still living in a past era, but that's what I want to build for my next project. I've even toyed with taking one of the old free plans and redesigning the frames with more vee. There is one on Svensons (sea King) which is based on a South African Ski Boat, made into an offshore centre console(ish) design. Would build a scale model first to see what its lines were like and make any adjustments necessary, but it does seem like an enormous amount of brain work.

Might also be a lot of fun! And should be sturdy enough by using the original plans sections and beefing up in high load areas just a tad. Might think about this a little more before I put the Haines on the market.

G'day CQ,
Yep I am from the same ilk when it comes to deadrise, I have some very well know relatives that build a well known F/Glass range of boats and was raised on a diet of these, Haines Hunters and our own Hartleys which consisted of a 19' 15 degree hull and a 17' 20 degree hull (the original Vixen). For me I have not seen a design that even comes close to Richard Hartleys designs that are now most likely some 35 years or more in age, they still can hold themselves against any modern design in glass or other methods of construction, which is why I have plans for two, now I say all that with the greatest respect to other designers and until Mark released both the Sportzmaster and Cruise Control my mind was set. Well the Cruise Control has the design elements that the Hartleys don't, mainly increased freeboard and swept sheer line, (and Mark, it does look sweet) an also now incorparates 20 deg at the transom so i am now busy hitting the overtime and fast considering putting the Hartley plans away. It was only a matter of time I guess before someone came up with offerings like these.

Cheers,
Kev

Thanks Kev,
Actually I'm spending a lot of time on these plans (actually I do on all of them), but in regards to this design and being that 98% of it is plywood construction, I'm really pulling the boat apart. This way as you build, the plans are all in sequence as far as construction is concerned. Right down to playing dot to dot when marking out the longitudinals and then dropping them into position. It's all there. The frames themselves are plotted out FULL SIZE" on mylar.
So far I'm up to 15 2ft x 3ft sheets and still going. I reckon in the end we'll be around 22 sheets not including the full size patterns.

The SportzMaster 19 plans were the same in layout and detail and they weighed 1.7 kg postal weight all up, but I reckon the Cruise Control plans will go slightly more
So glad I own a plotter !!! If only I could own the postal service ha ha

G'day Everyone,
Just thought I'd post what's happening in regards to the Cruise Controls plans to date.
The plans are drawn on large "D" size or 2ft by 3ft sheets except for full size templates which are plotted on mylar (6ft by 2ft sheets)
Plan sheets drawn to date:
1/ Profile & Plan sheet
2/ Arrangement Plan & Profile
3/ Lines Plan
4/ Cradle setup
5/Stringer/longitudinals and CVK setup
6/ Lamination Schedule
7/ Hull panel Measurements
8/ Hull plywood layout sheet
9/ Bulkhead 1 & 2 construction sheet
10/ web 1 & Bulkhead 3 construction sheet
11/ Bulkhead 4 construction sheet
12 Bulkhead 5 Consruction sheet
13 Bulkhead & Transom Construction sheet
14/ Full size Mylar Bulkhead Templates
14 Full size Mylar Bulkhead Templates
15/ Arrangement Construction Plan & Profile
16...
And we're still going.
It will probably end up to around 21 sheets so we're not to far away now!

If anyone is interested, I posted examples of the plans on our website under the "Drafting Table" page
regards
Mark

looking good Mark

Mark,

Havnt seem any updates of late was wondering how long till the plans are out.

Cheers

G'day Koala,
I planning on having them finished by the end of next week. I was hoping to have them finished a few weeks back, but we've had so many interuptions etc, that it's set us back.
Once they're finished, I'll notify here if you like.
regards
Mark

G'day all,
Well after a few delays and other boating projects, the Cruise Control Plans are now finally finished. Whew!
So, here's the final renderings of the design that a few of you may be interested in.
regards
Mark
