Subject: baidarka re - speedy outriggers
James Wharram catamarans have had lots of experience with
lashing outriggers :
Quote from one of Wharram www sites:
"9. Why do you lash the beams of your recent
designs, and is it safe?
For 35 years, the majority of Wharram designs have been
designed in the two hull deck assembly as controlled flexible
structures. In the early years I used rubber blocks on steel
bolt mountings. In recent years, I have been using the high
tensile strength and modern stretch characteristics of modern
ropes.
Using this method of lashing beams to the hull, fixed high
stress points are reduced, the lashings show visible signs under
stress and act as replaceable stress members and stress gauges.
Under actual working conditions the rope lashings have been
shown to act precisely in this way,and have proven to be easy to
maintain and replace when required."
