Sea Sled madness. It’s in my brain.

Sure!

 

Okay, it's making sense now.
There's another photo showing the diagonal lap joint.
I'll look. (EDIT: Post #1313, page 88)
Thanks John.
Fiddle-on!

 

Enormously stronger than a lap joint. Can bear huge vertical loads, and the vertical component isn't weakened like in a lap joint. It is susceptible to an impact on the outside edge, because the inside edge is chiseled down to a line. But the beam across prevents failure in that axis because it carries the load away.

 

Windows soon. Hopefully right about when the plague is over, and businesses are throwing out plexiglass by the truckload.

 

As I go through my own version of the design cycle, it occurs to me to wonder, what would I have paid a proper NA to prepare plans for me?

 

How long is a piece of string???

 

I talked to a naval architect in the USA some years ago, re asking him for some design help re a possible project to design and build a 'big' (20 m. long) ally cat here (but it never got off the ground) - his ball park figure for doing all the structure drawings in CAD along with DXF files for plate cutting was approx US$25,000.

 

Interesting thought.
I wonder what it's cost you without a NA...
(Answer may not involve monetary values.)

 

Depends on the SOR. If you want string suitable for tying newspaper around fish, not much. If you want your string to be suitable for use as a stringline, considerably more.

Dave Gerr wanted $15000 to complete the plans for his Al Sea Sled, Interdictor.

 

Probably around a thousand hours of research, design, consultation, and sleep lost while pondering.
About that again in actual labour.
Around 18000 in materials, insurance, yard fees and the like. Much of that wasted through missteps and mistakes.

 

For less than a third of the figures that are being talked about, all the information can be done to build that hull. But that, now, no longer matters.

 

Less than I thought. I would have needed a NA intimately familiar with sea sleds and strip plank composite.

 

But the satisfactions that you have had, the sufferings that you have experienced, that cannot be given to you by any NA. That is something that will stay with you forever.

 

I heartily agree TANSL. And if someone else designed Serenity, I would be building their boat, not our boat.

 

Here's some preliminary jib crane stuff from an old army buddy.
I'm picturing an Al tube half that long, dropped over a heavy wooden post, probably reinforced substantially with carbon tape, or glass. Just because tying that into the existing boat structure be easier.
