C-Trial-
There are two differences between the Sprint 400 and Sprint 600 windlass models from Simpson Lawrence of which I'm aware.
One is the motor, which is the 400 versus the 600 watt difference that accounts for the name differential. This translates into more pulling power and speed for the larger unit, as well as amperage draw.
The second is the gypsy. The 400 has a plastic gypsy and the 600 is metal, chromed brass, I believe. Here the difference is in how long it works before replacement is needed. The metal one is probably good for the life of the motor and the overall unit's life expectancy. The plastic one is shorter. I know of one person who had to replace the gypsy on the 400, but he was using all chain for the rode.
If you plan on keeping your C-Dory indefinitely, as most of us do, you might check into the cost of a replacement gypsy and add it to the cost of the 400 and see how that compares to the up front cost of the 600. I looked this up once and can't be sure of the exact figure, but I think it was about $260 (!). Then you get the bigger motor up front with the 600. HMMMMMMMM?????
Tyboo has noted before that 300 ft of 1/2" will fit in the locker of the C-D 22. Research it out in our library to be sure. You'll find discussion of the enlargement baffle (rear wall) of the locker there, as well as how to install a suitable, good looking drain.
This topic more than others is worthy of careful consideration, because every component of the system-
anchor,chain, rope, bow roller, windlass, locker, etc.,
must work in unison for the system to function. The whole thing works no better than the weakest link in a fully helm-operated system.
Hope this helps! Joe.[/i][/b]
