As the hosts of Car Talk used to say: When faced with a choice between inconvenience and possible death, people choose ... possible death. /Martin

What about watertight compartments? /Martin

Not there yet in Sweden. Mostly, I think, because many marinas are either club run or run by the local government. There are commercial marinas and the trend towards 'streamlining business' instead of serving customers is glaringly obvious. /Martin

I would assume so but I really don't know. I haven't considered that alternative myself. All my dagger boards and rudders, except the latest pair which are 100% carbon, have low density wood cores and so far none have failed me. By low density I mean just north of 300 kg / m³. Western red cedar, redwood, obeche... I think Ian Farrier saw this as the heavy but durable option. /Martin

Since the Young's modulus of the uni carbon laminate is way higher than for any of the other materials you must assume the carbon takes the load alone. The curvature of the carbon in your figure is not a problem. https://www.reflectometrist.eu/pages/daggers/index.html /Martin

Balmy 12 C where I am (N59.2, E18). Time to switch to winter tyres anyway as this will not last. Early November another year: And then you have people with inland climate in Canada and Russia who are already at -20 C or worse. /Martin

If you wait long enough even an old wreck can become an asset: https://www.vasamuseet.se/en /Martin

My battery, all 7.2 Ah: /Martin

According to a friend working as a marine engineer for commercial shipping there is only one difference in the anti fouling laws for pleasure boats and ships: The law acknowledges the fact that ships are not repainted every season. Hence, longer transition time for new bans. This is in Europe as far as I know so your mileage may differ. /Martin

On average every four weeks but it varies between years and during season. I use either a scrubber brush or a home made appliance based on a Scotch-Brite like cleaning pad sized 30 by 15 cm. Hull depth is a mere 25 cm so no diving needed. Hard to say. If memory serves I had these alternatives: Finding a source of illegal anti-fouling -- still needs cleaning but less often and only during second half of sailing season. Hempaspeed TF Hempel's Silic One which is more complex to convert to and softer. I was told it would not work on an a boat that lives on

Hempaspeed follow-up now that I have a few seasons worth of experience with this product. How often I have to clean and how easy it is varies from season to season. I don't know why marine life sticks better to Hempaspeed some years. Still not hard to remove though but if I wait too long removing barnacles will result in cratering the surface. Hempaspeed flakes as it ages. A little bit during the sailing season and then mostly at the water line. Then more and anywhere during the winter. The flakes separate mid-Hempaspeed, not at the interface to the primer. This year I had to do

The place is called Saltsjöbaden and is located SW of central Stockholm: https://www.openstreetmap.org/search?query=Saltsjöbaden#map=14/59.27928/18.30493 The main marina is located in the bay named Hotellviken. /Martin

Lives in the same marina as my boat: /Martin

Should work. Very few things thrive in both sea water and fresh water. The only thing I can come to think of right now is the eel and they don't foul boat bottoms. /Martin

Interesting. Based on what? /Martin
