    Beefing up the insides for JSD

    My understanding: the filler doesn't add much strength, it is to allow the cloth fibers to bend around that inside corner without crimping or forming too tight a bend. Is there any guide for fillet size vs laminate thickness?

    Beefing up the insides for JSD

    Yes - I thought the original spec nylon main line was to absorb shock loading? Anyhow, the brief vid of the stern taking breaking waves & the rudder flailing about do not look like a modern (fat butt) boat wants to use one.

    Beefing up the insides for JSD

    Yes, I noticed that. Have to check on sheer strength of bolts AND know how thick the laminate is around them. I have seen race boat deck hardware that was migrating along a deck by ripping thru the laminate - not a pretty sight. And are the bolts threaded where they go thru the lam or are they...

    Beefing up the insides for JSD

    I've installed two JSD anchor systems, so I can appreciate what you're going thru. You don't want failure. But short of having the build sced for the stern laminates and the a qualified laminate engineer, how do you satisfy (and pacify) the boat owner? Neither of the install's I did ever got...

    Beefing up the insides for JSD

    In the OP's pic up top, the bridle has a very narrow angle, so not much added compression across the transom. If one did want to allow for that, reinforcement would need to run across the transom a bit, not just filling in the corner. A fillet would ease the cloth around the corner, keeping more...

    Beefing up the insides for JSD

    Why? Loads are forwards, no need to re-enforce the transom

    Beefing up the insides for JSD

    I don't think you want to use any basic level cloth. You have conflicting forces to deal with: sheer load from the bolts will want the threads running vertically (normal to the load) and to carry the loads out across the hull will want fore/aft thread lines radiating out from bolts. I'd be...

    Beefing up the insides for JSD

    The possible max loads for a JSD (as per JSD) are the weight of the boat. There is nothing stock mounted on any boat (ex maybe a metal build) that comes anywhere near those numbers. Add in the need for a fair lead for the highly loaded bridle and you can usually eliminate anything not mounted to...

    Beefing up the insides for JSD

    These padeyes are to be mounted on the hull (not the transom) correct?? Then your 4 (each side) bolts are holding the load in sheer. Have you looked at how the bridles will attach to the padeyes? What happens when the hull slews to one side & the bridle has to wrap around the transom corner...
