Pearson 365 and 367

Due to an unfortunate mistake, there is a crack in our mizzen at the port spreader attachment point.  I would like to attempt TIG welding a doubler as a fix.  Can anybody a) confirm that the alloy is 6061 and b) provide the thickness of the mast material?  Thank you in advance.

Yes, it would be in the same location.  I was just kvetching a bit about it not being ideal.  Thank you for the picture, that is a nice setup.  I will most likely go for the risers, I will let you know in a couple days.  What would the best form of payment be?
If you have a second, what do you recommend as a method for nice sealed holes through the coach roof?  One method I can think of would be to oversize the hole, fill with epoxy, then drill the appropriate size through the epoxy leaving the core unexposed.  I am new to all this so bear with me.  Thanks.

Good morning.  We have had our '76 365 for a few months now and are enjoying it.  I was considering upgrading(?) from the weird triangular block main sheet arrangement (is this original?) and these would seem to do the trick.  The coach roof is not an ideal location for mechanical advantage...are there other downsides I am not realizing?  Thanks in advance and also thank you for a kind response to another post of mine re: engine removal this coming winter.  Take care.

New 365 owner, so I apologize if this idea is asinine.  Thinking ahead to the '25/'26 winter, I am trying to think of ways to get the engine out without fabricating that cool u-shaped bracket I have seen others do.  Here it goes:
With an engine hoist attached near the end of the boom and the chain dangling forward of the engine, use a long 2x4/pipe as a lever with the fulcrum being the point of contact with the hoist chain and the long portion going forward in the cabin.  It seems that I could get huge mechanical advantage and simply repeatedly lift the engine a bit, scoot it forward a couple inches, set down, slide connection between engine and lever, repeat.
Thanks in advance.

Greetings everyone.  I have been the recipient (and once or twice provider) of priceless knowledge on mirafiori.com while working on my father's '81 Fiat Turbo Spider--looking at this site I am anticipating the same kind of helpful jovial experience.
S/V Cetus (#22) is a 365 that just joined the family and seems to be in great shape.  My father and I are hoping to get quite a bit of use out of Cetus this summer in SF bay, with a haul-out next winter to do usual bottom preventive maintenance, pull/rebuild engine, replace fuel tank, possibly re-step main and re-rig (I would really like to go synthetic or swageless to make it as DIY-reparable as possible).
I have read a fair amount of posts already and appreciate the help.
