The cache is not located at the posted coordinates, you do not need to get a boat!
The cache can be found at the following location:
N61 A.BCD W149 EF.GHI
A = [C]
B = [KAlSi3O8]
C = [Mg3Si4O10(OH)2] minus 1
D = [Al2SiO4(OH−,F−)2]
E = [Ca5(PO4)3(OH−,Cl−,F−)]
F = [SiO2]
G = [CaSO4·2H2O] + [CaCO3]
H = [CaF2] x 2
I = [Al2O3]
