You write this chapter with an offshore boat. Outside, redundancy, range and a deck on which you can still work safely in the weather are what count. Deep-V, self-draining cockpit, high freeboards and a protective hardtop form the basis.
Offshore boats combine range, reserves and redundancy. They are safer in waves, hold their course when drifting and offer a working area for heavy natural bait and jig rigs. If you want to use weather windows, you need: CE category at least C for significant waves/wind, protection (hardtop/bulkhead), freeboard and a self-draining cockpit. Storage space and organisation (emergency/tools/spare parts) are not optional, but mandatory. Offshore fishing is freedom with responsibility. The right boat provides protection, range and redundancy, modern technology extends your strike window, and clear routines turn a weather window into a safe fishing day. With planning, crew discipline and the right set-up, the big sea becomes the best fishing ground in the world.
Motor dimensioning: Take the licence, weight, typical crew and desired range into account. Maximum motorisation usually provides reserves (at a lower continuous speed), but is not a must.
Fuel management is more important: Separate lines/filters for twins, water separator, range planning with 30 per cent reserve as a "rule of thumb"
