[Alberg30] backing plate

[Philip Bartlett]

A picture circulated a while back of #499 "One Less Travelled" that shows a
bow platform similar to what you describe. You can still view the photo at
http://www.alberg30.org/pictures/contributed/sailing499a.jpg.

Does anyone have any closeup photos of this platform or others?

Philip

of not having a bow-mounted anchor roller. I looked at other designs, and
talked to a lot of people, but couldn't find a plan that I liked. The front
of a late model A30 is a bit "busy". Finally, I came up with the one I am
currently building.

> The goal was to have a bow platform carrying an anchor roller. The roller
should handle several anchor types, including Fortress, Delta, and Spade,
and hold them securely. It must be usable without interfering with my roller
furling drum. It must be strong enough to hold the forces generated in a 60
knot blow. It must not detract from the looks of the A30.

both for it's strength and for it's versatility in handling different
anchors.

> The platform to hold the anchor roller is made of white oak which is
finished with multiple coats of Sikkens Cetol. The dimensions are: 11" wide
by 24" long by 1½" thick. There is a slot in the middle of the platform to
hold Revolution's stem fitting.

> The stainless anchor roller is bolted to the right of the slot, and to the
far right side of the oak platform. The furling drum overhangs half the
roller's width. This means that maneuvering the anchor shaft in and out of
the roller shouldn't be difficult. Also, much of the strength of the steel
roller is imparted to the wooden platform it is bolted to.

> Oak shims were cut (the shape is strange) to enable the platform to sit
fair on the lip of the cast stem fitting. When cutting these shims, as well
as the original wooden platform, I first used rigid pink insulating foam
board, (which is 1 1/2" thick., and is easy to work with), to make dummies.

>
> >From the back end of the anchor roller to the back end of the wooden
platform, I have covered the top of the platform with 1/8" stainless plate,
which then continues aft and rolls over the back edge of the anchor platform
& goes down to the deck. This will protect the wood from the effects of the
anchor rode dragging on top of it.
>
>
>
> To let me pull the anchor up from any place on the foredeck (and avoid
interference between the rode and the furling drum), I have put an inverted
roller with a removable shaft on the steel plate behind the anchor roller.
This keeps the rode horizontal while it is passing under the furling drum.

> Under the back end of the wooden platform is a white oak block which is 5"
wide, 2.5" fore & aft, and 4" high. The affair is secured to the boat by ½"
by 7" stainless bolts which go through the 1/8" stainless plate, the 1.5"
platform, the 4" block, and the ½" deck. There is a 1/8" stainless backing
plate (6.5" x 8") epoxied under the deck.
>

>
> An additional stainless securing strap holds the front of the platform
down. It is 1" by 1/8" by 14", and runs from one of the front horizontal
stem screws under the front of the platform, and up to the platform.

> If you have any further questions about this installation, let me know.
Keep in mind that the installation is not yet complete, so I can't evaluate
it's performance or it's success in meeting my goals yet.
