Another small boat design, by Jay Bliss. http://ftp.ij.net/wc.../photos103.html



I know many people view small boat design as boring and B.P. wrote that they are even crude.

Fair comment, I thought. Perhaps that's why I don't see some lovely Perry mini 6.5 design, dinghy or trailer sailer on the interweb when I got curious and looked.

I have always been a fan of crude boats, boats with hard chines on, to be even more crude. :)

Dad had the chined Wayfarer copy in FG, called the CL16 and he built me an El Toro I sailed the snot out of.

The hard chines on the whitewater kayaks I have had, changed the sport. Wavesport's market share success is carried by it's wonderful chined design of the '90's. It is a different boat with a different job, but that's how chine fondness grows.



Yes, small boats are fun, you don't get the same connection to wind and water on a big boat even a racing one.


I saw this boat up close several years ago in Maryland while at a woodenboat regatta.  It was a great example of a lot of ideas executed without much in the way of knowledge both from a design standpoint, and also from a practical sailors standpoint.  The fellow that designed and built the boat was super nice, but definitely disappointed in how dreadful the performance was.  My friend of mine and I were not!.... so many things wrong with this boat.  That picture is probably the best possible angle.  A transom view would demonstrate what I'm talking about clearly.



What is so wrong with it? Is it slow, dangerous, badly mannered, impractical?




I would guess that it looks like a triangle in plan view.  Not enough volume forward to get it to plane easily, and the deep forefoot, low volume forward and the LCF way aft probably makes it dig the bow in and difficult to steer.

In Topic: How long Can A Fiberglass Sailboat Last?

I think there is a better question than will an ancient fibreglass sailboat that had 10 times as much resin and glass required when new.


Why the fuck can't somebody design a carbon mast that doesn't blowup if you look at it too long?


Boeing and the other aerospace companies manage to build a plane that lasts for at least 30 yrs in real service in more or less their original build. EB designs and builds subs that last forever.


NASA can design and build two rovers that drive around Mars for 10 yrs.


You've named things that cost hundred of millions to billions of dollars.


You could build a more durable carbon fiber mast, but it would cost more and probably weigh more.

Slight thread drift, but on the topic of bulges, etc....


I went to the boatyard to see if the winter cover had held up in the windy weather, and discovered they had put a late model, pre-Marlow,  Hunter near my boat. I was interested in the stern.




I had seen this boat in the water several times, and had never noticed the chine shape aft. It's mostly underwater, and it's slightly rounded (radius chine?) but it's a chine none-the-less. And then there is the acre of almost perfectly flat wetted surface. I didn't take a picture of the keel. It looks pretty crude to me, but what do I know about keels. 

Fragile looking rudder.Narrow keel, which puts a bending load on the keel bolts.  A friend ,who used to charter them, says Hunters are as slow as a bureaucrats brain ,compared to  his brentboat ( Prairie Made).


Had a great  sail up the Strait ,SE 20 knots and dry. Been in Comox for over two weeks, far too long for any port. Blew like hell the following day ,up to 54 knots. Glad I left when I did. Pefect day for a sail up the Strait


Tell me Brent, do you like cold pizza for breakfast?  Are you a Coke or Pepsi guy?  To me there isn't any choice, it's Coke or nothing.



Pepsi MAX or GTFO - Twice the caffeine.

A quick summary:


On various forums, Brent has argued with:


Naval architects

Yacht designers

Mechanical engineers

Other types of engineers

Professional boatbuilders




And they are always wrong.

And he is always right.

Because he is a "full time" cruiser living on a crudely welded steel boat that he built himself.

A classic Dunning-Kruger type.

If Bob had not existed, others would have done the same ,as many have.  He has done nothing  as innovative as what I have done, but simply followed what others were doing. He is a follower, not a leader.


The Dunning–Kruger effect is a cognitive bias in which relatively unskilled individuals suffer from illusory superiority, mistakenly assessing their ability to be much higher than it really is. Dunning and Kruger attributed this bias to a metacognitive inability of the unskilled to recognize their own ineptitude and evaluate their own ability accurately.
