We are new to cruising and will only attempt local coastline to begin with. On board are some basic Plastimo 'Storm' Lifejackets which don't have crutch straps. They are also a bit uncomfortable to wear all the time. Hardly anyone seems to wear lifejackets. Is it sensible to buy better lifejackets such as 'Typhoon' style or go for inflatable style? Also manual or automatic? Better to be safe than sorry I think!
