If so what angle degree would we need to achieve to lower our overall height to 40 ft to be safe.
Can you sketch anything
Really appreciate the advice
Thanks j
This is a very viable option if you do something like my suggestion or Atoll's. The closer the mast is to vertical the less the strain there is.

A couple quick notes on the boom method. I thought a picture would be worth a thousand words but it is only if you know what you are looking for. Never use the topping lift to the end of the boom, use the main halyard well secured both ends. It has to be cleated to the mast because the whole thing moves eh?

For a dedicated tabernacle mast the side stays do need to be in line with the mast step with the turnbuckles on a parallel plane.. But.....

If not you need to use side stays with adjustment. In my case I use the running backs led to tackle to adjust the varying stay length. like I said move it a bit and adjust everything.

While I agree a Prout boom is a bit short for a partial lower it wouldn't matter as much. What I would suggest is making a temp longer gin pole instead of 2 at a angle. In my case I found a suitable section tree and went logging but I live in the sticks. Remember that boom end is secured to each side with tackle to keep it in column and adjustable.

As I said yes you will have to lower your mast forward, just like a Searunner actually but you are in luck as the mast is set up for it. Look on line for videos.

If you can get that photograph or link to the manual, it might help here for my single handed mast raising and lowering. Thanks in any event for your post!

I'm plotting a plan to raise and lower my mast on a SeaRunner 25. I'm hunting for that manual you mention. Thanks for your post!..https://goo.gl/photos/2fDFocTY6UjToF6S8

The searunner construction manual is a free download off outrig.org. Download the Searunner Construction Manual … | OutRig Media
Remember a Searunner mast tilts forward letting you use the mainsheet for a tackle but the boom needs to be secured by a halyard to the end and side to side lines. There are pictures of a 31 in the manual. The loads aren't big for a 25 which helps but take all the precautions.
