Thinking About Cabin Construction

Wednesday, March 16, 2016

Now that the boat is ready to be flipped, Im thinking again about the cabin.  Heres the plan, in general, for the completed shantyboat.


Id been giving some thought earlier to the cabin layout, but finally sat down and planned everything out using real measurement.


In clockwise order from top left:
  1. Small galley with 2-burner stove and sink
  2. Couch with resident dog and cat
  3. Bucket shitter (entered from the aft deck)
  4. Aft stairs
  5. Lounge chair
  6. Woodburning stove
  7. Table / chairs
  8. Fore stairs
Now lets get down to brass tacks:  Looking at wall construction.


This is the side wall, first a sketchy sketch, then a more accurate one.  Pretty simple really.

It took some thought to place the windows in a vertical position that felt right. The expected window position of the inside and the outside are kind of at odds since the floor of the cabin is dropped nearly two feet below the level of the deck. From the inside, I want the windows to be more or less at eye level and not too high. And from the outside, where the cabin appears to sit on the deck, I want the windows to be a little above the midpoint of the cabin.

I decided on slightly tall windows at 3 ft which resolves the issue to some degree.  Three foot or so from the floor inside and just above the midpoint of the cabin outside.


The original cabin plans call for 2x3 structural members turned parallel to the wall. I originally considered using perpendicular 2x4s in standard frame construction so Id have natural nooks and crannies between the studs that would be easy to turn into storage.

So Im kinda confounded on which method I should choose.  Im trying to measure the pros and cons of each.

2x2 Wall Construction
Pro:
Lighter
Takes less space
Less material
Easy to connect
Con:
Harder to diagonal brace
No nooks between studs
Note:
Recommended by pretty much everyone in the boat community, but feels flimsy to me.
2x4s Parallel with Wall
Pro:
Takes up less space
Con:
Heavier
Harder to connect
No nooks between studs
Harder to diagonal brace
Note:
Makes thinner walls and weirder window openings.
2x4s Perpendicular with Wall (standard framing)
Pro:
Natural Nooks between studs
Conventional technique
Easy to connect
Con:
Heavier
Takes more space
Note:
Standard construction, typical window framing, including sills.
2x3s Perpendicular with Wall (compromise)
Pro:
Natural (smaller) Nooks
Like conventional technique
Easy to connect
Lighter than full studs
Con:
A little heaver than 2x2
Note:
This might be a good compromise. Solid framing with reduced weight.

Hopefully, youll weigh in with your expert and experienced opinion. Or maybe youll weigh in with your totally inexperienced pet theory, thats fine too.

After we flip the boat and add the front and rear decks, well be coming up on building the cabin pretty quick here.

Boat Construction Using an Existing Design

Boats can be and are regularly built using an existing design. This is a cost effective way to obtain plans for a proven boat. Click here for an example project. To build a boat from one of our existing plan sets a royalty must be paid. Please contact us for a quote.

In many cases existing plans are modified or updated. For example a classic sailing yacht originally designed and built using carvel planking will often be re-engineered and updated for cold molded epoxy construction. Another common example may be modifying an interior arrangement to suit ones particular needs. Please contact us for further information.

Didi 950 Construction Starts

Tuesday, March 1, 2016

Michael Vermeersch has started building his Didi 950 prototype in Ravenna, Ohio. This is the prototype of a very new design. Micheal is building from a pre-cut kit that we supplied and reports that the quality and fit have been excellent thus far.

 Yesterday Michael and a friend set up the bulkheads on the building stocks and he is now preparing to fit the backbone components to tie the bulkheads together.

This design has been drawn to comply with the Class 950 Class Rules. Watch this space for progress reports on this boat and the other Didi 950s being built in Australia, Latvia and Greece.

Please note that precut kits for our plywood designs supplied in USA must be ordered from Dudley Dix Yacht Design and not from the company that cuts them, Chesapeake Light Craft. For more info and pricing go to our plywood kits page.

Composite Construction for one of our Plywood Favourites

Wednesday, February 24, 2016

Here is some teaser information.

One of our popular plywood designs that has been around for a few years is about to be elevated in status. Tooling is soon to start in Australia for it to become a production boat. I will tell more about it in the next few weeks. For the moment, suffice to say that it is one of our most popular plywood designs and it will be available both as complete boats and as hull/deck/bulkhead kits for owner completion.

It is to be produced by a boatbuilder who has a depth of experience and knowledge spanning many years that will ensure quality products, strong and well-finished.

Watch this blog for more information in coming weeks. The design is being built in plywood by many amateur boatbuilders around the world, so I am sure that it will be popular as a GRP boat as well. Two boats are on order before the mould construction starts.
