Cabin Height

 I'm very concerned with having a cabin that I can at least sit fully upright in.  I don't want to be crawling around on my hands and knees like some sailboat cuddy's appear to be.

The plans include a note of putting a hinge at the front of the cabin and having it tilt up so at least the back end is higher.  Filling the open gap with a cloth like a pop-up tent.  Many years ago I saw one at a boat show.

I've pondered on various methods of having a roof that raises and lowers, but any scheme is either awkward or complicated. 

There's a guy in Australia who built a Redwing-18 and raised the cabin roof a mere 2 inches.  Enough for him and his wife to sit upright on the bunks.  I'm thinking this is what I'll do, just make the roof higher.

I wanted to also see how this would change the appearance.  Here's the original drawings modified to show the changes.  (the pictures are animated gifs)

Drawing 1:  Raising the cabin 5 inches.  Not a terribly bad change, but makes the overall shape odd somehow.

 Drawing 2:  To diminish the effect, I decided to also raise the motor-well and the anchor-box.  The plans call for an 'anchor box' to be built on the fore deck just in front of the cabin.  A place for the anchors, ropes, etc.  Raising the anchor-box 2 inches and the motor well slightly less, helps to even the overall proportions, to balance out the cabin change.

 Drawing 3:  The plans call for a large wooden cleat in the middle of the fore deck.  I doubt I'll do this type of cleat.  Removing it changes the look of the sheer line forward.  Also, the plans place the ship's wheel on the front of the motor well, where I intend to place it on the rear of the cabin.  

Drawing 4:  This covers the underwater portion of the boat's profile.  This makes the original appear as a fairly low profile.  Part of the original design has the pilot sitting on the benches of the cockpit near the motor well and being able to see out over the top of the cabin.  With the raised cabin will I still be able to see over it from the bench, or will I need a higher seat or chair than the standard cockpit benches?
