{ "type":"Feature", "properties":{ "id":"209af2e6-8411-4c86-8bcb-4a493b87f0b9", "date_updated":"2025-07-07T07:02:03.319000", "title_en":"Asmalsund", "title_no":"Asmalsund", "description_en":"

The southern part of Asmaløy is light, gray stone. As the strait narrows northward, the land becomes slightly wooded. The east side of Spjærøy is generally more fertile. It is also steeper towards the sea. There are scattered buildings on both sides of the strait.

\n

A surface layer of fresh water generally flows southward, but the current is usually of little significance for navigation.

\n

The strait is shallow and quite unclean in both the southern and northern parts, but with a draft of up to 4.5 m, one can pass both east and west of Kobbernaglen (low, dark reef) and Siverlaks (iron rod northwest of Pikesten).

\n

Coming from the east, the best route is between Kobbernaglen and Pikesten, where there is an even sandy bottom.

\n

A bridge crosses the strait at Rød.

\n

Coming from the west, one can pass between the shallows southwest of Spjærodden with Vikervarden directly over Kobbernaglen. When the iron rod on Spjærflu aligns with the point of Trelltangen, one can set course into the strait north or south of Siverlaks (iron rod). The strait is clearest along the western shore.

\n

Once Asmalsund is passed, one can continue northward on the west side of Tjeldholmen and Gåseskjær or south of Tjeldholmen and out into the main approach. In the latter case, one shouldn't turn eastward until the north point of Møren is aligned with the north point of Stamholmene. This course is maintained until one has passed the 3.3 m and 1 m shallows south of Tjeldholmen.

Den søndre delen av Asmaløy er lys, grå stein. Ettersom sundet smalner N-over, blir landet litt skogkledd. E-siden av Spjærøy er gjennomgående mer frodig. Den er også brattere mot sjøen. Det er spredt bebyggelse på begge sider av sundet.

\n

Et overflatelag av ferskvann flyter i alminnelighet S-over, men strømmen er som regel uten særlig betydning for navigeringen.

\n

Sundet er grunt og temmelig urent så vel i søndre som i nordre del, men med inntil 4,5 m dypgående kan man passere både E og W om Kobbernaglen (lavt, mørkt skjær) og Siverlaks (jernstang NW for Pikesten). 

\n

Kommer man fra E er det beste løpet mellom Kobbernaglen og Pikesten, hvor det er jevn sandbunn.

\n

Bru krysser sundet ved Rød.

\n

Kommer man fra W, kan man passere mellom grunnene SW for Spjærodden med Vikervarden midt over Kobbernaglen. Når jernstangen på Spjærflu fås i pynten av Trelltangen, kan kursen settes inn sundet N eller S for Siverlaks (jernstang). Sundet er renest langs vestre land.

\n

Når Asmalsund er passert, kan man fortsette N-over på W-siden av Tjeldholmen og Gåseskjær eller S om Tjeldholmen og ut i hovedleia. I det siste tilfellet svinges ikke E-over før N-pynten av Møren er overett med Npynten av Stamholmene. Dette medet holdes til man har passert 3,3 m- og 1 m-grunnen S av Tjeldholmen.
