and massive backing block. Similar require-

ments should be met on FRP construction.

On aluminum boats (like Imagine), the

details are similar, but the rollers are fabri-

cated from heavy aluminum plate welded in

place.

Another common problem with anchor

rollers is installing double anchor rollers so

close side-by-side that only one anchor can fit

at a time. See the narrow double roller in

Figure 24-9, then look at the bow-on view of

this same double roller in Figure 24-10.

Notice how the second roller is completely

hidden by the one anchor in use. You cannot

handle two anchors at the same time in twin

rollers such as this.
