Dancow: Did a Lagoon 380 earlier this year out of Antigua. Not sure I would call them challenges just differences. I'll go in your order
1) Dagger Boards - not on the 380.....stubby mini-keels...just under 4' draft
2) Windward Sailing - about 50 degrees or so if my memory is right...depending on sail quality......play with traveler to help
3) Lateral Drift?.....not sure what you mean here, two hulls help it track pretty straight
What to watch out for:
1) Windage - Between freeboard & Cabin shape....you can get surprised
2) Beam -Don't forget in close spaces.....crew communications help alot
3) Conditions - You will not get the same "feedback" as a monohull when the
winds climb...especially with Winter winds....don't get overpowered
4) Draft - don't get over-confident with images of being 2' from the beach, you can still damage the hulls, rudders & props hitting rocks, coral, etc if you get too greedy on that shallow spot ...and no it did not happen to me but I've been a spectator to it in Belize on another Cat charter....you can get close but your chart & even more important eye sight better be good
5) Traveler - that thin adjustment
line is really loaded up....so wear gloves while adjusting......that did happen to me
6) Docking (side tie for water, etc) - try to arrange on Port side (
wheel & controls) as it is easier to judge your distances & assist with
lines if necessary but even more important do it upwind.....especially with any breeze, as windage will not help.
7) MOVING ABOUT - the cockpit especially has many levels/steps to it including a step down then OVER to get into the Saloon ....easy for crew to feel like you cannot slip or have to hold on while on the Cat.....wrong. Watch out for
hatches near rear hull steps, areas that do not have non-skid on them and interior cabin sole when wet
8)
Hatches - don't forget to clase before getting underway...as waves/spray will still get that high
9) Tramps - cushions add comfort for happy hour.....drinks sit nicely on fiberglass divider
Good News:
1) Two engines - Helps manuvering alot - yes, it will spin on its "axis"....
2) Space - for comfort & entertaining - no comparison to mono
3) Anchoring & Mooring - easier to see / access
Ask away if You have other questions
P.S. Forgot One - Watch the headroom as you move from deck or helm into / across cockpit as it is easy to bump head on Bimini frame
