Modifications > Bowsprit 

 

The bowsprit is sheathed in 1/4" s/s around the outer edges and with structural cross bands across the top. The sheathing is screwed into the wood with 1/4" wood screws and thru-bolted down through the cross bands with 3/8" bolts.

You can see the attachments here and the tangs built to receive the pullpit stanchions. The turnbuckle is Hasselfors from Sweden, 316 stainless still almost new looking after 17 years of constant exposure to sail water. The bobstay is 5/16" diameter, one size larger than the forestay, which is the rule with gauging bobstay size.

The bobstay attaches to a welded tang that that also received the forestay. The bends in the tang means that even if the welds should fail, the tang will lock the bowsprit in place and the rig will still have continuity. Note that the anchor platform is welded to the bowsprit as well.

At the inboard end, the s/s surround is thru-bolted to the hull on each side.

The bobstay attaches to the hull using part of the old tang from the stem head fitting. It is thru-bolted with two 3/8" bolts to a reinforced glassed-in backing plate. Note the caulking is 5200, applied in 1995 during the last refit. It is hardened and cracked. I will use 3-M silicone this time around.

From the Top, you can see how it attaches to the foredeck. The bowsprit is made up of three planks, the center plank taking all the directed stress of the rig, the two side planks providing width to walk on, and as a platform for the pullpit and ground tackle. Notice how the pullpit mounts to the side rails of the s/s surround.

 

The s/s cross support secures the center plank with a 1/2" thru-bolt.

You can see the rot clearly in this shot. I broke my own rule here: Never, never NEVER paint a wood spar. Awlgrip as you can see is not protecting the spar as much as it is hiding the damage from me. The rot started at the glue joint and traveled under the paint. The new bowsprit will either be natural or coated with a clear coating. Note the Wichard eyebolt for the staysail stay. It helps tie down the sprit to the foredeck and it attaches down through the anchor locker to the backing plate for the bobstay chain plate with its own turnbuckle.
