lets say it is mounted perfectly vertical . when you are on an incline and sideslope together it would never be vertical . these marine ones will give a reading that should be within 5 degrees of true . when sailing you are pitching and yawing at the same time so should still be accurate +/- 5 degrees . i just want it to calm me down win the seat is up my a$$
but thanks for all the tips
i will not go by gauge alone but is just another tool for having a rough idea of side slope degree . thanx again
