[Public-List] Alberg without an engine?

[Mike Lehman]

Clayton,

Racing one design is the best way to test the performance of any boat. I 
used to race my Alberg quite often and with a two-blade prop aligned with 
the keel. I switched to a 3-blade prop so therefore could not 'hide' the 
prop and noticed about 1/4 knot difference in performance while sailing. 
There was a significant performance improvement in motoring and maneuvering. 
I have always had an engine, first 20 years the Atomic 4 and for the past 15 
years a Universal M4-30 diesel (about 50 lbs lighter than the Atomic 4)...I 
have not noticed and performance differences due to the differences in the 
weight of the engine...now let a crew member sit on the stern 
pulpit...that's a different story! That's unsupported weight!

Subject: [Public-List] Alberg without an engine?


Hello all, I've been sailing my new Alberg 30, Hull #349, around British 
Columbia for the past month and loving every second of it. Hoping to draw 
from everyone's knowledge in this forum..............I'm wondering if anyone 
has or know of anyone who has sailed their Alberg 30 without an engine for a 
significant period of time? I've read that the stern sort of "squats" with 
the engine in her and mine definitely does. A previous owner installed a 
Yanmar 3HM35F (35hp, 350 lbs dry weight). The biggest question is does 
removing the engine and larger 3 blade prop, significantly improve the 
performance? I know Yves Gelina sailed around without one, but have not 
found anything where he argues the point one way or another.
Thanks everyone,ClaytonS/V "Tanager"Port Townsend, WA
