    Magazine 88 is not due out for another seven years, although the Editor is doing her best!  I think Brian means issue 18.

    Martin, 

    I have made a shear legs for my Corribee 21, and it has made launch day a lot easier. I use an icicle hitch to grip the tapered mast.

    I used some old carbon fibre windsurfing masts, which worked brilliantly and are very light. Recently, I added a couple of feet of steel tubing - it just so happened that tubing from my local agricultural co-op (as used for cattle crushes) slid nicely into the masts. 

    I don't stow the legs on board, but it would be easy to do so. 

    I found the following links very useful: Freedom 21 shear legs, Freedom 21 notes

    For a small boat like mine (I can float her off the trailer) I highly recommend making up a set of legs.

    Declan.

    Hi,

     

    After difficulties in arranging to get the mast up this year,  not to mention the expense, I'm wondering about the shear leg arrangement mentioned in PJR.

     

    I love to hear from anyone who has tried this. Ideally the legs would be stored on board so Ive been thinking of sectional tubes that would slot together. Sectional aerial poles can be had online for a small cost but would they be strong enough? I guess the mast weighs in around 30kg,  what might the loads be on the legs be? Then theres the more expensive carbon tubes.

     

    Any thoughts would be much appreciated.

    Regards

    Martin
