Geocache Description:

Kätkö sijaitsee Reposaaren linnakepuistossa. Koordinaatit vievät linnakepuiston portille.
Cache is located in Fortress park of Reposaari. Coordinates lead you to the gate of park.

Reposaaren rannikkopatteri rakennettiin sataman ja kaupungin puolustamiseksi 1935. Patteri laajennettiin linnakkeeksi vuonna 1939. Linnake on entisöity 1990-luvulla ja uudelleen keväällä 2008. Linnakepuistossa voit nähdä 60 vuoden takaiset tykkiasemat, korsut, tornit ja bunkkerit.

Voit etsiä kätkön joko annetun N-koordinaatin avulla tai kiertämällä puiston ja keräämällä tarpeelliset tiedot E-koordinaattia varten.

Ilkivallan vuoksi osa tarvittavista tiedoista ei ole löydettävissä, siksi D ja I kohdat on annettu!

Lopullisen kätkön N-koordinaatit ovat N61.36.432

E-koordinaatit E021.YY.YYY saat laskettua seuraavalla laskukaavalla:

A = englantilaisen laivapatruunan tyypissä oleva luku ???/41-AL
B = ammuksen lähtönopeus (m/s)
C = tykkiasemien valmistumisvuosi
D = tähystysetäisyys tornista kirkkaalla säällä (km) (22m)
E = tykin kantama (m)
F = Canet-tykin mallissa oleva numero ???/45-C
G = tykin ammuksen paino (kg)
H = rannikkopatterin valmistumispäivämäärän kuukausi
I = tornin korkeus maanpinnasta (m) (12m)
J = rannikkopatterin valmistumispäivämäärän päivä

(A * B) – (C*D) – E + F + (G * H) + (I*J) + 416 = YY.YYY

Coastline battery of Reposaari was found to defend a harbour and a city in 1935. Battery was expanded into fortress in 1939. It was restored in 20th century and again at spring 2008. In fortress park you can see 60 years old cannon stations, dugouts, tower and bunkers.

One choise is to find a cache by using just given N-coordinate. The other choise is to go around in the park and collect all information needed to calculate E-coordinate.

Part of the needed information is missing, so correct answers to D and I is given.

Final N-coordinate of the cache is N61.36.432

You can count E-coordinate E021.YY.YYY with following formula:

A = the number in english cartrdge ???/41-AL
B = starting speed of shell (m/s)
C = completion year of cannon stations (same as battery was found)
D = lookout distance from tower in clear weather (km) (22km)
E = firing range of cannon (m)
F = the number in the Canet-cannon ???/45-C
G = weight of shell (kg)
H = the month when coastline battery was completed
I = heigh of tower (m) (Height of tower from sealevel is 17 m) (12m)
J = the day when coastline battery was completed

(A * B) – (C*D) – E + F + (G * H) + (I*J) + 416 = YY.YYY

Since all signs are in Finnish, it might be littele bit difficult to find all information needed. Therefore there are some hints added in English version compared to Finnish one. With hints and some guessing it is possible to find a cache.

Additional Hints (No hints available.)
