[C320-list] Garhauer Davits

[Robert Seastream]

One thing I discovered this weekend about the Garhauer davits:  The 
crossmember is only secured by setscrews, which can vibrate loose.  I  
had to tighten them this weekend.  It would have been bad if the 
crossmember fell off.  The 'T' endcaps that hold the lifting line 
assemblies have both setscrews and predrilled, pretapped holes for 
included screws.  I'll be making modifications to provide the same 
support for the crossmember ASAP.  Other than that, it's a great 
product.

Another thing:  Just outside Portsmouth harbor, we almost lost (at 
minimum) our gas tank due to catching a heavy wake from a passerby off 
our starboard quarter.  The dink (Avon Bombard 240) tipped inward 
towards the stern of our 320.  Fortunately, our 8 hp Honda was well 
secured to the dink transom, and I'd padlocked the gas tank to the seat 
with a cable and lock.  While the tank did go in the drink, we were 
able to recover it.  Afterward, we tied a short line from the dinks' 
aft lifting handle to the lower end of the davits vertical support so 
as to limit this sort of travel.  I don't want to carry the 80 pound 
Honda on a stern rail mount.

The way we lift our dink is via lines with rings centered and secured 
in the middle.  The line is secured with bowline knots to the D rings 
at the bow, and to aftermarket U bolts installed near floor level at a 
45 angle.
