The prod itself is an aluminum tube and (it could have been built in Carbon )and the stainless strut is extremely thick walled. I could estimate the weight of the prod at 12-15 kg and the strut at an additional 5-6 kg. The design is straight from the plans built exactly to Ian Farriers drawings for the prod and is original to the boats year 2001 build. 1 Quote Link to post Share on other sites
Young Entertainer 59 Posted June 24, 2021 Author Share Posted June 24, 2021 so i am ready to get an end made now, an i have a bit of an idea of what i need, going to be single tack line that exits the fitting and clips back to a mounting point, and a bobstay that loops over the top and connects back to the boat So i am needing to now find someone who can make it if there are any recommendations, preferably in carbon, or on acetal if that is strong enough Quote Link to post Share on other sites
Kick Ass 47 Posted June 24, 2021 Share Posted June 24, 2021 We did one in alloy and is ok but I think the norm is acetal? Need to find someone with a lathe. Quote Link to post Share on other sites
Young Entertainer 59 Posted June 24, 2021 Author Share Posted June 24, 2021 a lathe i have, what i dont have at the moment is the knowledge of the materials, but acetal seems to be the go to product for this sort of thing 1 Quote Link to post Share on other sites

Making up a custom bobstay out of carbon and aramid wound between 2 points. Cow hitching the bottom through the hole and lashing the top. This will be retractable so the bobstay cant have any stretch as you need to be able to tension the bobstay with the prod out line. On motorboat we had a D ring through the bow and the bobstay went to half prod as the angle was too tight to go to the end and added too much compression into the prod. This worked well as it was also the code zero point. On the sunfast we had a dogbone inside the boat for the bobstay as it was in the anchor locker so didnt need to be sealed as well. That was the tidiest way as the bobstay just disappeared into the bow. Are you running a fixed or retractable prod? What’s that you used for the hole in the bow ? I’ve been trying to source suitable strong tube that’s not carbon ($$) can’t find small diameter fibreglass or G10 Quote Link to post Share on other sites
