Monohull vs cat on extended passage?
Spend some time cruising and living aboard and you will hear the same info from multihull cruisers.
The boats don''t go to windward well so plan your route accordingly. They don''t tolerate loads...that makes them slow like monohulls but without windward performance. 40''cat = 2 people lightly cruise loaded. The motion while anchored is sharp and uncomfortable...swells lift one hull and it falls, then they do the same with the other hull...double motion and fast. Chose your anchorage carefully. Running with storms can take you along as fast as the storm moves so don''t run. Windvanes are tough to keep adjusted due to rapid ap wind changes. Finding slips can be a chore or you have to pay for two. Your inflatable can be kept under the hulls so it stays out of UV rays and lasts longer. Shallow draft a plus. Cost a negative. Nice sunning platform when capsized.
