You are lucky it does not cooperate in reverse! Thant means it is docile going forward! I have owned Alberg's and now have a Tahitiana 32 with a full keel
. These large keel boats are a dream sailing forward. The Alberg
is also more comfortable in rough seas than almost all modern boats of comparable size. Spend some time finding the sail balance that will allow you to sail for hours with just a bungee on the helm
As for reverse... you usually do not do it for more than a few minutes anyhow. Try not turning the rudder
all the way (only maybe 2/3) because the rudder
will stall easily in reverse and will then have less effect. On our Tahitiana... the rudder is pretty much useless. We have 2 LONG (10 foot) pike poles with big ribber tips. We use these to fend off boats, docks, etc when trying to leave the marina.
As Robert Sailor said spring lines can work wonderfully. You can gracefully pirouette the piling or cleat at the end of the dock
in reverse by looping a fairly long line over it and keeping both ends. Secure it slightly aft of mid ship, and drop one end to retrieve it after you done your reversing and throw her into forward to leave.
It also help to laugh when you are blown up against all the boats opposite your slip and are struggling to get her going in the right direction. This is where the 10 foot poles come in. Other sailors have been curious about our ridiculously long pike poles... until they watch us try to leave in a blow. Others in the marina will get used to you struggling in reverse and after a while more and more will help out. Don't be embarrassed... the "Old Salts" know why you are struggling with her, and who care what the others think anyhow.
She is an absolutely wonderful boat and will serve you well.
