Pocket cruisers

Hello Brian,
Thanks for bringing back to life again this old thread.
These times I have very little activity at BD forums, due to some other "entertainments" I have to take care of.
Presently I am recovering from a heart surgery last week and I hope I will soon be able to take up normal activity again soon.
Warm wishes to you and all my BD friends.

 

Holla Guillermo!

Sorry to know about your surgery but I'm sure you will feel your usual self in no time.

Here's wishing for your speedy and successful recovery. And GET BACK TO WORK!....just kidding.

This subject thread had some VERY interesting discussions that I thought might be applicable for this 'coastal cruiser' trawler design I'm working on resurrecting. ...even though at 40 feet it might be a little bigger than a pocket cruiser. ....all in definitions, ha...ha.

I'm not really interested in the technicalities as to whether it is a displacement vessel or a semi-one by word definition, I'm just trying to determine the best underwater hull shape to use for this vessel to travel at her best displacement speed, AND possible to exceed that hull speed at times without too much extra HP.

 

Sorry to read your condition Guillermo. I wish you well and take very good care of yourself.
I love this boat you posted

 

Estar ben pronto.

 

Get better quick!

 

Guillermo, Hope you recovery is going well. I've been there too and am now mostly stable. One thing is certain, we will forever look at what is important in life differently than before.

 

Best wishes for a speedy recovery, my friend.

 

Guillermo,

It has been 2 months since your post, would you update us?

¿Cómo está? ¿Está mejor? ¿Más o menos?

Thank you, friends.
Surgery was perfect and I'm recovering well, although now experiencing some anemia as a collateral consequence. But nothing serious. I hope to be able to come back to my usual life in a couple of weeks at its most.
Warmest wishes to all of you.

 

I hope your Mrs. is cooking with cast iron pan. I brought my iron up quick with one.

 

The cooking where Guillermo lives it's to die for. The best you can have.
Guillermo glad you are recovering well and very soon resuming your normal activities.

 

Thankfully I live in an area rich with Spanish cuisine.

"According to Paul, even at a casual cruising speed Cindy Lou should rock back on her haunches and lift her nose a bit. He took that into consideration when he laid out the rocker in her bottom. But of course, she isn't designed to ever plane. Instead she'll slip along at a dignified pace, quietly and majestically, while sipping on fuel instead of sucking it down."

This aspect of rocker intrigues me. One can have symmetrical rocker or skew the curve fwd or aft. If the rocker curve is mostly aft I would think the boat would be more efficient at low speeds, make very little bow wave and be best for a rowboat or at least running less than hull speed. A completely symmetrical rocker line could be most efficient. But rocker mostly fwd (as w Cindy Lou) the rocker aft is only slight. One could put all the rocker fwd and the aft run would be perfectly straight. On such a boat w her bow above the water the hull presented to the water would be basically a planing hull. There may be a lack of stability but I imagine planing speeds could be reached.
I assume PAR chose to put most of the rocker fwd for flexibility. He has no control over how big of an engine a builder would put on Cindy Lou. Most people are inclined to more power than less.
I'm interested to hear what others know and think about this subtle difference in flat bottomed boats.

 

Looking at one aspect or only one part of that aspect will usually lead to wrong conclusions. Looking at only the profile view of the "rocker" may not even show the actual rocker. for instance, looking at the immersed volume distribution forward to aft will almost always offer a different view of rocker. Only in a completely symmetrical hull will these be the same and that is still only part of the story.
