Hope everyone is keeping safe. We are proud new owners of a Northshore 38 ( Novice sailors and our first yacht).
It's been very frustrating as new owners since start of covid restrictions with this new strain and would like to get bulkhead repairs done up at Pittwater before bring her down to the harbour.
We are considering to do further repair/ remove a bigger section of the port side bulkhead, old leak through chainplate, knew this from owners survey we did before buying. Has anyone has done this kind of repairs on single spreader, single chainplate fixing amidships without dropping the mast?
Trying to avoid extra costs as the mast was re-steeped and standing rigging replaced in 2017. Shipwright will only do repairs if mast is down. Our boat is 1985 vintage and only has one set of midships chainplates, and no structural point amidships to tie down with halyards?
If we do this work and drop the mast now, we can not attend site and do any other upgrades and painting on mast myself, due to Covid restrictions. We have to move boat in the next few weeks to new mooring in Rose Bay.
Any advice would be greatly appreciated. David
I'd be calling in a rigger to be sure but I'd have thought you could brace the mast to a couple of strong points.
I would certainly get new chainplates made and replace all the bolts pretty quickly.

Unfortunately not much use just replacing chain plates and bolts if the surrounding bulkhead is compromised mush.

Does the boat have aluminum toe rails?
No unfortunately these were not features of the North Shore design and nor was a midships cleat. Some sort of temporary chainplate would need to be rigged on the hull or deck. Personally I would perhaps go with fixing something to the top sides of the solid glass hull with a couple of holes drilled through which could be easily patched later rather than drilling the deck which is balsa core and therefore harder to patch and could result in wetting the core whilst the work is in progress.

You are sailing so use headtrack at two points or stanchion bases
I would seriously review the whole boat and any other work that is required, then look at pulling it out of the water, drop the mast and have everything repaired in a yard. You need to make it as easy as possible for the shipwright to carry out the work. The shipwright I use would generally be working on 3-4 boats at the same time. So while he is waiting for something to dry on your boat he moves to the next boat and does another job, with all his tools readily available. I you want to work on the boat yourself at rhe same time delay everything for 2-4 months and have it done after the COVID restrictions are listed. On a new boat there are bound to be jobs you have not identified.

Yeah much better idea. Lockdown has had me off my boat for way too long full stop forgotten what she looks like :-(
As posted before if I recall right, Edcon cut 316 ss flatbar to length for the chainplate straps.

For the bolts suggest Bumax 88 from here; an excellent company - get their advice of a nickel based thread lubricant / sealant to use also, to avoid nut to bolt thread galling.

Bumax 88 is the high strength 316 stainless grade far stronger than the standard 316 grade bolts.

Hi all
Thank you for your advice, some great insights from the collective responses. I've decided to delay bulkhead work, sail boat to Rose Bay in the next couple of weeks, once established mooring. The photos make it seem worse than it is, as repairs using hole saw repairs in 2017 weren't finished aesthetically: not even sanded the excess epoxy, no veneer or stained to match. All the bolts were upsized to metric and replaced.
The boat has a Lowrance 9 chart plotter. Any advice what are the best paper charts of the Sydney/ Pittwater east coast.
