I am not sure, will 8hp or 9.8hp Tohatsu be enough to move 3,2 sib much better than 4hp? I am begginer - I don't know. Will it plane at weight of 200kg (two people + gear) + 27kg (engine) + 30-60kg (additional gas)? If yes, what in case of calm wind and waves. Will not it stop a sib from planning?
It is true that my sib weights 42kg (a hull only 30kg) but I have a luggage trolley. And I even modified it to be possible to use it on stairs. However I have to make some additional test. And note that I lift only one side of package to place it on a trolley. So I lift only half of weight. I also have some idea how to get it to the car - I try to use a line and blocks. But I haven't tested the idea yet. Transom wheels are also good idea.
6 knots is not very bad. This year I made short trip on river and estuary waters. One day we swim over 10h on small sib and without any engine. Only our hands. And we made almost 24km. The average speed was about 2,4km/h. So about 1,3knots! However I realize that a river and a lake is not a sea. A small wind is enough to make a trip impossible.
A sens of humour is very good
. Yes, there are no tides on south Baltic but it has an opinion of sea which has short waves. So, we know what waves are
I live on south of Poland so I have similar way both to Baltic and Adriatic. A bit further are Black Sea, Aegean Sea, North Sea and others.
