  1. This is very good reading of Slocum's book: https://librivox.org/sailing-alone-around-the-world-by-joshua-slocum/ /Martin
  2. Reminds me of the loss of Drum's keel during the Fastnet Race in 1985. /Martin
  3. Here in the Northern hemisphere it is time for maintenance. One of the items on my list is to re-sleeve the main halyard. It has an 8 mm Dyneema core and the sleeve is busted where it sits in the halyard clutch. The current sleeve extends 1.5 m above the clutch for reasons that do not apply any longer. Hence the question: How much sleeve is needed above the clutch? /Martin
  4. Does this help even if it is not the article you are looking for? http://www.boat-links.com/foils.html Added 11 h later: Why do you need flat-sided foils? Class rule? Beating my own drum (yes, about dagger boards but still true for rudder blades): http://hem.bredband.net/b262106/pages/daggers/index.html /Martin
  5. I know you live in a sunnier place than I do but still I think it should have lasted longer. What type of wood? Oak and epoxy for instance is non-trivial to make work in my experience. Then we have tho option of KISS. If swelling/shrinking with variations in humidity is not an issue for this tiller I would consider good old one-pot varnish. Yes, it will need to be re-done on a regular basis but it is not hard work. A cover will extend the service interval considerably. /Martin

    Kelp harvesting? /Martin
  7. Only going dead down-wind so far. /Martin
  8. Yes, the Baltic Sea is known for not destroying old wrecks. The same goes for the Black Sea I understand which means there is a real possibility of finding ancient Greek mercant ships, Bysantine vessels... If you ever visit Stockholm this museum is a mandatory thing on yout to-do list: https://www.vasamuseet.se/en /Martin
  9. So what strings did you recommend to hold his rig up? /Martin
  10. A comparison I did when the Seacart 26 was new and my Tennant cat was almost 30 years old: There is not much difference in weight according to rating certs I have seen. The new boat is the heavier one... There was a Seacart 26 moored in my marina briefly but I never saw it sail and had no chance to compare pace. /Martin
  11. Depends on what you think /Martin

    Window sealant

    Buthyl rubber sealant has work fine for me. Applied in 1986, still no leaks in 2019. I don't know what brand name but this looks right: https://www.ebay.com/sch/i.html?LH_CAds=&_ex_kw=&_fpos=&_fspt=1&_mPrRngCbx=1&_nkw=butyl+rubber+sealant&_sacat=&_sadis=&_sop=12&_udhi=&_udlo=&_fosrp=1 This stuff neither cures nor dries out. It is still soft and sticky. /Martin
  13. Teflon bonding anecdote from my distant past: Some electronic boards are made from Teflon and back in the late 1980s I needed to create a multilayer Tefon board. I used a product from 3M for this. It was thermoplastic bond film: Put a piece of it between the two Teflon bits you want to joint. Add pressure and increase temperature (no, I dont remember how much) and wait for a while (no, I don't remember for how long). It was pure magic. I did a test run and trying to pry the teflon parts apart I broke the teflon but not the bond. 3M sold this product and anything related to printed circuit boards to someone many years ago so there is no point in approaching them about this line of products. /Martin
