tá an treocht sách ard, gan a bheith níos measa ná cruach ardchaighdeáin, gan trácht ar chomparáid FRP. Smaoineamh ar a lán daoine dhearmad gur cineál cruach é FRP, ach níl sé. Is é ainm iomlán FRP GRP ná GlassFiberReinforcedplastics. Ón ainm iomlán, is féidir linn a fheiceáil gur plaisteach treisithe snáithín gloine é FRP. Is ábhar ilchodach é comhdhéanta de roisín sintéiseach agus snáithín gloine. .
If the hull is hit by the same force, the fiberglass yacht will have holes, and the aluminum alloy yacht may just be recessed. This is why most voyage ships use aluminum and steel ships. When you are sailing in an iceberg, aluminum yachts are more secure. In fact, it is not only icebergs, but other obstacles that may collide, from underwater reefs to wood and containers floating on the sea.
We have heard stories from time to time that the aluminum yacht hit the reef. Although the people were trapped on the yacht for several days, they were still rescued safely. This is due to the fact that aluminum yachts are not easy to break and sink into water even if they are impacted and dented, and aluminum yachts are relatively easy to repair. If the same reef hits a FRP yacht, you won't be so lucky.
