Slowboat,
interesting to read. Yes, „Temptress“ seems to have been a well and boldly sailed boat, then the modern Californian ULDB Sleds came in the game ...
No comment about furling mainsails at all, and not a single word regarding this feature aboard a Swede 55. In the late 70ties, when Swede 55 was displayed at the Hamburg boatshow, I had the pleasure listining to a conversation about a mizzen mast on the aft deck ...
Regarding the logo, it would cost something and perhaps the best and reasonable way would be several Swede 55 owners ordering it. I would then ask my sailmaker plotting it etc. pp. I made a fairly detailed 1:1 (german style) drawing ...
Swept back spreader, this is a common question and I know of another owner considering it. I would not do it for the following reason: The main bulkhead takes the mast compression (down) and the pull (up) of the upper and intermediate shrouds as one unit.
The existing chainplate for the lower aft shroud is definetely not made to hold the pull of the upper and intermediate shroud.
Perhaps, after consultation of a naval architect or structural engineer, you could laminate an extra knee to the hull and deck at the desired position, but I would not do it, because the entire rig relies on the bonding of the knee to the hull. And it adds weight to the construction, this being a critical point at Swede 55.
Should you have a possibiliy to check the weight of the boat, please do so and let me know (with a remark what was in the boat when weight checking was done, fuel, water in the tanks, gear, sails ...) I have heard horrible numbers. The design was planned for net 7,75 metric tons.
A selftailing 28 Winch for the runners with 1:2 tackle to tighten, few more seasons with your boat and you will be used to the runner handling (no big deal). You can sail the boat with two, the helmsman doing the runners, your companion doing the jib sheet. Should you have friends you want to make familiar with sailing and your boat, doing the runners is a nice job to introduce them to the pleasures offshore ...
And the backstay is holding the mast anyhow. The boat has a conservative mast design, which means you need the runner to tighten the headstay in a fresh breeze. It is more a matter of nicely tuning the boat.
If I were in your position, I would keep the boat as it is, repair it where necessary and go on sailing for seasons. There will be enough to do to get it back in shape and have everything working. Plus there can be surprises (electrical issues, systems, refrigerator, pumps, engine, leaking windows), and then there is a life ashore, women (keep the portside nut!), family, the necessity to make the money before drowning it in such a nice hole like „Rosina“ ex „Javelin“ is.
I would remove those heavy bow rollers, which seem practical but don’t really fit to the design. Saving weight is good, but wouldn’t it be nice to mount all stanchions for the lifelines? How about your pushpit. I have mine at home right now, might make a good template to have a new one made if you really want one (should there be kids playing, guests or girls sunbathing on the aft deck).
Cheers, Zebra
