It was shown that there was a positive correlation between the hullweight and the last grain weight.
相关分析表明，谷壳的重量与最终粒重呈极显著正相关关系。

But if the size is too large, that will cause hullweight and ship resistance increase. Fatherly, that will affect the fast of ship.
但尺寸的过大，又会导致船体重量增加，引起船舶阻力的增加，影响其快速性。

The goal of ship optimization design is to obtain the lightest hullweight and the largest cabin capacity, while on the condition that satisfies the requests of strength and general arrangement.
