Thanks Aaron. If Brent real project's experience is that welding hours for 36
footer are about 100 hours, then 140-150 hours for 38-39 footer looks reasonable
(still probably need to double it for first time builder).

Travel speed for SMAW (stick welding) using mix of E6011, E7024, E7018 will be
similar (may be even faster compare to GMAW-S in previous example. Let assume it
is the same).

So, we have estimate for 38-39 footer:

Hull 3/16" = 46.3 Hr
Deck, Cabin, PilotHouse, FootWell 1/8" = 39.4 Hr
Tween Keels (both) 1/4", ½" = 30.9 Hr
Tank top 3/16" = 7.7 Hr
Skeg, Rudder 1/8" = 13.1 Hr

Which gives us about ~ 140-150 welding hours.

P.S. Correction for formula: RealisticTime = Time_in_Hr / 0.1
P.S.S Next step to find the cost of consumables (for SMAW and FCAW-SS).
