With good charts
, as up to date as possible, guide books
with good sketch charts
, and an experienced eye to discern the relationship of water
color versus depth
- it is rarely necessary to actually take the dinghy
out and "stick" the area.
- - But in areas where there is a lot of doubt and/or the depths on the charts, etc., do not match very closely your depth sounder
readings (corrected for instrument position) then "sticking" the area using the dinghy
is proof positive of what the depths are currently. I keep the collapsible or extendable 12ft or 14 ft boat hooks on board and have marked them at 1 foot increments with a laundry
marker. The boat hook make a great solid "stick" to read the real water
- - For instance, the channel from Marigot, St Martin
inside the Lagoon
south from the bridge has been reported to be silted in and although it was rumored to have been dredged, nobody knew for sure. What with the huge variations in boats draft
relying on previous boat's success is not all that reassuring. So I anchored in Marigot Bay and took the dinghy under the bridge and down the channel with my boat hook "stick" and measured the actual depths and where the deepest parts
of the channel were in relationship to the channel markers.
- - Additionally, I noticed boats anchoring
south of the channel in an area on the chart where the depth
was shown as less than 5 feet. "Sticking" the area showed an actual depth of 8 to 10 feet so I had a good uncrowded area to anchor
as others avoided the area due to the charted depths.
