Re: Storm Jib

You’re absolutely right Peter. My main interest in that very small jib in the picture (I don’t have one like that) is that with the second reef in the main and my #2 jib in about 18+ knots with both sails as flat as possible, I found a lot of lee helm which is scary in a blow. But you are right that...

Re: Storm Jib

Thanks Peter! The part at 26. minutes into the video I hadn't thought about (always something to learn). The other thing that's not mentioned in the video is asymmetrical the hull shape when heeled which causes the boat to round up. These two things together should compensate for the unbalanced sail...

Re: Storm Jib

I've been doing some time wasting thinking about sail balance. The drawing below shows a rough estimate of centre of effort vs centre of lateral resistance. The CLR is VERY rough - I cut out a cardboard template of the below waterline parts of the boat and balanced it on a pencil. Actually I think m...

Re: Showcase your Investigator

PS. you MUST wear gloves when battling barnacles underwater! I got a scratch on a finger that never really healed. Finally got the doctor to cut a chunk out of the finger before it came good.

Re: Showcase your Investigator

I first used an old bread knife but I found that an old fibreglass batten around 500mm in length works much better and is less likely to cause damage. Plus, it fits nicely up the front edge of the centreboard which is where I found most of the barnacles stopping it from coming down were living. Now ...

Re: Hawkesbury and tiller pilot

Hi Andrew, "glue extra wood block inside coaming for brass bush" I found that the GRP laminate at the top of the coaming was about 1/2" thick (or more) so I just drilled and press-fit the bronze socket fitting with some polyurethane to seal. Not sure if this is best practice but it's ...
