The second feature of the site, a 100-foot by 20-foot fragment of the Nilsson's side, rests in 12 feet of water, roughly 2,000 feet southeast of the main wreckage. This sizable piece consists of 55 sets of frame timbers and long, intact spans of inner and outer hull planking. Most frames are paired together with 1-inch diameter iron fasteners, the heads of which were peened (flattened out) over a large washer to prevent the fastener from slipping through the wood.

A fragment of the Nilsson's centerboard can be found at the wreck site.

Interestingly, several frame sets near the aft portion of the centerboard trunk are tripled, suggesting the need for additional strength in that area. Aside from a few of these loose fasteners, no artifacts were found on the site, save a single iron pig (small block of iron). This was illegally removed from the site sometime after 1997.
