Installing a Selden or Trogear Adjustable Bowsprit?

I have a 2005 Hunter 33 with furlex100s jib furling system tied into the second of the four holes for this purpose on the anchor roller assembly. I'd like to fly a spinnaker, and I am looking for a relatively simple, lowcoast upgrade. There is no intent to race this boat, rather for allpurpose downwind cruising mostly SE USA Atlantic. Does anyone have positive/negative feedback from installation of a Selden extendable gennaker bowsprit [ Gennaker bowsprits – Seldén Mast AB ] on a Hunter? The forward end of the bowsprit bolts to [the presumably, two forward-most of four holes in) the anchor roller assembly, while the aft end is secured with a padeye affixed with screws through the deck. Is there a strut or similar under the deck far enough aft of the anchor locker to provide the purchase necessary to withstand the downward force from sail load? I don’t like the idea of screwing the padeye into deck, only… They seem much more invasive of the deck and hull, but what about Trogear [ Trogear Adjustable Bowsprits ] kits?

The Trogear looks like nice kit. Definitely not low cost. I'd go with the Selden but I don't have enough room without major surgery.

I am also inclined to Selden ... but I am oping someone in this forum has experience and knowledge in identifying a suitable place on the deck for the padeye screws ... I have never seen a manual that shows the location of such struts ...

It's field-fit. Start with a cardboard tube of approximate length and see where the ends fall. There could be many possible solutions for your particular boat or none at all. The ring needs to be anchored against the lifting force, and the padeye end needs to resist downward and lateral forces.

On your size of boat, I would look at the designed (purchased unit). Either will work.

I looked hard at the Selden. I decided too build a similar rig using an aluminum pipe tube (2" diameter, thick walled) and the stainless bow fitting with a welded tube that let the pipe slip through it. I kept the length to about 4 ft. This put the sprit out in front of the bow and maintained most of the sprit on the foredeck which I secured to the hard point in the foredeck.
Here is a look at the assym I had made on my Montgomery 15.

The Trogear sprits look really good. Drilling through the bow for a mounting tube is scary, but it'll be solid forever.

I couldn't justify the price tag on our C-22, and did a similar design myself (link is to the first post - several more follow). If I did it again, I'd probably use carbon instead of aluminum.

Also think about how it will impact anchoring for you; we have a system that's working for us, but in an ideal world, I might have a Vulcan (non roll-bar) anchor on a roller just under the sprit (instead of just above it), and a retractable bobstay, so we could anchor without removing the sprit. Food for your thought process.

I really like the look of the Trogear bowsprit. I would be worried that fastening a cantilever to the anchor roller would impart much more substantial upward load than the roller was designed for. The Torgear has a bob stay that takes the load. You may be able to add a bob stay to the Selden sprit as well to take the vertical load but it does not look like it was designed with that in mind.

Good point. My understanding is that it's pretty standard to add a bobstay to the Selden for a code zero (higher load than a downwind asym). But that's just gleaned from Internet research - I haven't seen it in practice.

Beautiful!
Do you have any pics of the build?

It is nice to get the spin tack out in front of the headstay, but I have acceptable performance flying an asymmetric using a block on the anchor roller held with a soft shackle. It's removable and quick to set up. The block lets me adjust the tack height and a set of parrel beads keeps the tack in close to the headstay. I dont have any pics of my set up, but it's similar to this:

I'm actually wondering now if I even need to add a bowsprit ... so long as I get a block on a soft shackle tied to the anchor roller as you are showing in your pic ... what value would that bowsprit add? maybe necessary for a very large gennaker only?

Yeah I wound not want to sink screws into deck unless I can find purchase in something more solid beneath it....

That looks great. I wonder where that hard point on the Hunter 33 would be ... need to get schematics .... I wonder if I am overthinking this and tacking the gennaker to the anchor roller is not the most practical and yet still functional KISS solution ...

I recently added a selden bow sprit to my hunter 340. Like you I tried to do a lot of research but finally deceived on the selden. Actually it was very easy to install. It has worked perfectly so far. I use it for my asymmetrical as well as for a code zero with a top down furler. It is also very easy to move it so that I can get to the anchor locker. you need to be sure that you use seldens charts for correct placement. I mean if you are using code zero you can only have the end of the sprit so many inches past the mounting ring. On th pad eye I only installed one that I leave it on. it is basically right over/bulk head. If I can be of any help pics or whatever just let me know. Good luck

Thank you for your feedback ... now lots of questions! :) What do you mean about the pad eye, "... only installed one that I leave on"? How did you locate the bulkhead under the deck? How did you reinforce/seal the core under and immediately around the screws from the padeye? (epoxy?) How many double fairleads did you use on each side? 3,4? Did you attach the twin cam lock to one of the metal lifeline stanchions, or affix it some other way? I'd love to see whatever pix you might have, but would not want to put you to any trouble.

The sprit attaches in the back to a type padeye. the sprit comes with 2 of these padeye. The forward one is the one that attaches the back of the sprit at the point that you want the forward part of the sprit to extend out In front of the boat. the Other padeye is placed aft of the first padeye. The spirt has a small spring type that allows you to unlock it from the padeye it is attached and moved to the other. In other words to can store it on the aft padeye and slide the sprit out and attach it on bow padeye for use. The max distance out that the sprit can go is determined by I believe the righting reaction of your boat. This is factored by a chart that selden puts out. i just looked at the boat and put the forward padeye just aft of the anchor locker where I knew the was a bulkhead. I just did this so I knew it would support. The forces on the sprit are upward at the forward ring and down at the back of the sprit at the padeye. Like you I was pretty worried about the whole thing but it was one of easiest things I have done to my boat. I love it
