It All Adds Up!

It always amazing to me just how the combined weights of the little things add up! It was about a year ago that I last weighed all the individual components as they were then. Weighing them again now I'm finding that much like many of us as we celebrate Christmas, they've all put on weight! The completely rigged Shan Skailyn is 35.9 kgs heavier than what Gary Dierking specifies in his book. I'm not sure how I feel about that. As I ask where the weight comes from, it's not peanut butter truffles and candy canes, though that may be what did it to me. A great deal of it comes from the accumulated weight of contingencies and other little accoutrements deemed necessary, along with the fact that many of those were made from the only kinds of wood available to me, the heavier, more dense stuff. Wherever I could, I went with the lightest material I could find. But I think now I'm seeing just how much all that adds up. And of course those stainless steel crossbeam hinges didn't help, though the additional weight is a small expense to pay for the added benefit. Over time, as I find the urge to replace certain parts, I'll definitely be doing what I can to get materials that are lighter weight. I can see remaking the leeboard, stub mast, and maybe even ditching the steering oar (or remaking it if I find myself using it enough. And then there are some little pieces that would be easy enough to remake using lighter material with little consequence to my time. For now, for me, it matters not. I'm super pleased with my boat and can't wait to get it out and sail it! Just a couple months till the maiden voyage!

Fore hull section 23.0 kgs (50.7 lbs)
Mid hull section 23.7 kgs (52.2 lbs)
Aft hull section 23.5 kgs (51.8 lbs)
Aft iako 9.8 kgs (21.6 lbs)
Fore iako 9.8 kgs (21.6 lbs)
Ama 14.2 kgs (31.3 lbs)
Sail + spars + rigging 15.0 kgs (33.0 lbs)
Stub mast 5.5 kgs (12.1 lbs)
Steering oar 3.6 kgs (7.9 lbs)
Rudder + tiller + hardware 3.6 kgs (7.9 lbs)
Leeboard + hardware 6.5 kgs (14.3 lbs)
Motor mount 3.0 kgs (6.6 lbs)
2 seats + support pola 7.5 kgs (16.5 lbs)
2 seats + support pola 7 kgs (15.4 lbs)
2 small polas 5.2 kgs (11.5 lbs)
----------------------------------------------------------------------
TOTAL WEIGHT (fully rigged) 160.9 kgs (354.7 lbs)

I'm not sure how Shan Skailyn's weight holds up to others' builds. Anyone care to comment? What kinds of total rigged weights are we seeing out there?

Total weight so far

OK, so yesterday afternoon on a whim, I decided I'd weigh everything up that I have done so far... or nearly complete. Right now is probably a great point to weigh a bunch of these things since all the fiberglass is done and the first coats of paint are on and dry already. Very little weight will be added later with the exception of some little bits of hardware here and there. So without further adieu here are the weights of individual parts:
Hull fore section 22 kg
Hull mid section 24 kg
Hull aft section 21 kg
Both crossbeams 15 kg (7.5 kg/ea)
Assembled ama 14 kg
Leeboard 6.5 kg
Rudder assembly 2.5 kg
Roughed out stub mast 7 kg
----------------------------------------------
TOTAL 112 kg (246.9 lbs)

Hull weight... so far

OK, took a few minutes today during lunch to weigh up the individual hull sections as they are right now. Other than the mast step, glass and paint, there really isn't much that will add significant weight at this point. So these numbers are probably pretty close to what she'll end up weighing.
Fore section - 19.5 kgs (~ 43 lbs)
Mid section - 21.5 kgs (~ 47.5 lbs)
Aft section - 19 kgs (~ 41.5 lbs)
TOTAL 60 kgs (~ 132.5 lbs)
That's not too bad, is it? Considering what's left (sail, rigging, ama, hollow beam iakos, etc) I would guess loosely that I'll easily tack on another 40 kgs. That would put the completed Shan Skailyn at around 100kgs (~ 220 lbs). But that's just guessing there.
